Uhf Versus Vhf - Which Two-Way Radio Frequency is Better?

There are two major formats for two-way radios. They are Ultra High Frequency (Uhf) radio and Very High Frequency (Vhf) radio. Neither frequency band is inherently great than the other. They each have their pluses and minuses. Both formats are efficient ways to chronicle with other person. But how do you resolve which one will fit your needs? Let's go over the key components of both frequencies to help you decide.

Two-way radios chronicle with each other through use of radio waves. Radio waves have separate frequencies, and by tuning a radio receiver to a exact frequency you can pick up a exact signal.

Radio waves are transmitted as a series of cycles, one after the other. You will all the time see the "Hz" abbreviation used to indicate the frequency of a radio. Hertz is equal to one cycle per second.




Radio waves are measured by kilohertz (kHz), which is equal to 1000 cycles per second, or megahertz (Mhz), which is equal to 1,000,000 cycles per second--or 1000 kHz. The connection between these units is like this: 1,000,000 Hertz = 1000 kilohertz = 1 megahertz.

You may also hear the term "wavelength" when you hear about radio waves. This term is from the early days of radio when frequencies were measured in terms of the distance between the peaks of two consecutive cycles of a radio wave instead of the amount of cycles per second. Lower frequencies yield a longer wavelength.

While wavelength measures distance between the peaks of cycles, frequency refers to how long the measured time is between the "crest" and "trough" of a wave arriving at the source. So frequency measures time instead of distance, but they are essentially both saying the same thing.

What is requisite about wavelength for two-way radios is that it affects transmission range under confident conditions. A longer wavelength as a general rule lets a radio signal travel a greater distance.

Lower frequencies or wavelengths have greater penetrating power. That's one of the reasons they are used for communicating with submarines. Vlf radio waves (3-30 kHz) can jab sea water to a depth of practically 20 meters. So a submarine at shallow depth can use these frequencies.

So from what you read above you may think Vhf is all the time the great option for a two-way radio no matter where you are using it. That's not necessarily true. Even though Vhf has great penetrating capabilities, that doesn't necessarily make it the great option for buildings. Remember the conversation about wavelength above? Wavelength has a big impact on transmission.

To elucidate this let's assume we are communicating from one side of a commercial construction to the other. In between these two points is a metal wall with a three foot door in it. Metal is an enemy to radio waves and they typically don't pass through it.

For our example let's assume that the Uhf wavelength the radio uses is about a foot and a half long and a similar Vhf radio is colse to five feet long. These are in the ballpark of their general wavelengths.

When the Uhf transmits its signal the foot and a half long wave will pass through the door since the door is wider than the wavelength. The Vhf signal will be totally reflected since it is wider than the opening to the door.

Your microwave oven is an example of this. The glass front door has a metal mesh with very small holes. Microwaves being a very high frequency have wavelengths that are only some inches long. The mesh keeps the microwaves trapped in the oven but it allows you to see inside because light waves have a slight wavelength.

Just dream walking through the construction carrying a five foot wide pole. You will encounter the same challenges a Vhf signal encounters. Now dream walking through the construction with a pole that's only a foot and a half wide like a Uhf wave. There are lots fewer doorways you couldn't get through.

The one difference is that wireless signals will jab through drywall, masonry, human bodies, furniture, wall paneling, and other solid objects. All these objects will reduce the signal vigor though. The more dense the object, the more it reduces the signal. Vhf will jab these obstacles great than Uhf, but that doesn't necessarily mean that Vhf is great for indoor applications as we will talk about in the Uhf section below.

In our example above we assumed you had a metal wall with an opening. If you reverse this and you have a three foot metal object in front of the transmitting radio, then Vhf would win. Since the object is three foot wide it will totally block the Uhf signal whereas the Vhf signal will get colse to it. Lower frequencies such as Vhf diffract colse to large smooth obstacles more easily, and they also travel more indeed through brick and stone.

For most applications, lower radio frequencies are great for longer range. A broadcasting Tv hub illustrates this. A typical Vhf hub operates at about 100,000 watts and has a coverage radius range of about 60 miles. A Uhf hub with a 60-mile coverage radius requires transmitting at 3,000,000 watts.

So there is no clear option for which is better, Vhf or Uhf. There is a lot of "black magic" to radio technology so it's not all the time easy to tell which will work great for your application. To help you resolve on the best technology for you, more detail about each one is included below.

Uhf Radio

Uhf tool operates between the frequencies of 300 Mhz and 3000 Mhz. Until recently, it wasn't widely used. Now, the Uhf radio frequency is used for Gps, Bluetooth, cordless phones, and WiFi.

There are more ready channels with Uhf so in more populated areas Uhf may be less likely to have interference from other systems. If you are in an area where habitancy is thin, Vhf should work fine for you. Not too long ago the Fcc also opened up a new Vhf frequency called Murs that is so far not heavily used in most areas. There's more about Murs below in the Vhf section. If you are in an area where interference from other radios may be an issue, Uhf transmitters and receivers could be your best option unless you use a Murs Vhf radio. Uhf is great at squeezing through bodily barriers like walls, buildings, and rugged landscape. Anything that obstructs a radio wave, will weaken a radio signal. Uhf lessens that effect. Though it may not travel as far, Uhf radio waves will traverse colse to obstacles great than Vhf.

To highlight the differences in indoor range, below is an citation from a brochure of a prominent two-way radio maker on the startling range of one of their lines of handheld Vhf and Uhf two-way radios:

"Coverage estimates: At full power, line-of-sight, no obstructions the range is practically 4+ miles. Indoor coverage at Vhf is practically 270,000 sq ft and 300,000 sq ft at Uhf. Expect about 20 floors vertical coverage at Vhf and up to 30 floors at Uhf. Note: Range and coverage are estimates and are not guaranteed."

Vhf waves are not very good at seeing their way colse to walls, buildings and rugged landscape. Therefore range will be significantly reduced for Vhf radios in these environments. That may not necessarily be a problem if the range needed is only a few hundred feet. You can also add an external antenna to an indoor Vhf base hub that will reduce or eliminate this problem.

One of the downsides to Uhf is that the Fcc requires you to get a license to control in these frequencies. Although many frequencies in the Vhf business band also wish a license. If you choose a radio in the Vhf Murs frequencies you can control it without a license. Uhf tool is normally more expensive. The components need to be finely tuned and are more expensive to construct. This does not mean it's necessarily better, just more expensive.

One benefit of Uhf transmission is the physically short wave that is produced by the high frequency. That means the antenna on the radio can be shorter than an equivalent Vhf radio.

Vhf Radio

Vhf tool operates between the frequencies of 30 Mhz and 300 Mhz. Fm radio, two-way radios, and television broadcasts control in this range.

Both Uhf and Vhf radios are prone to line of sight factors, but Vhf a slight more so. The waves make it through trees and rugged landscapes, but not as well as Uhf frequencies do. However, if a Vhf wave and a Uhf wave were transmitted over an area without barriers, the Vhf wave would travel practically twice as far. This makes Vhf easier to broadcast over a long range. If you are working mostly outdoors, a Vhf radio is probably the best choice, especially if you are using a base hub radio indoors and you add the external antenna.

Since Vhf has been colse to longer and isn't as involved to make, tool is normally cheaper when compared to similar Uhf equipment. One disadvantage to this tool can be its size. Since the frequency waves are bigger, an antenna must be bigger.

Vhf radios also have a smaller amount of ready frequencies. Interference with other radios could be more likely to be a problem. However, the Fcc recently made this less of a problem when they opened up the Murs frequencies. The 150 Mhz frequency is a Citizens Band radio spectrum that is called the Murs service. Murs stands for Multi-Use Radio Service. This assistance is for use in the United States and Canada. It is a low power, short range assistance in the Vhf 150 Mhz Citizens Band radio spectrum. There are 5 channels in the Murs frequencies with 38 privacy codes under each one that enable you to only pick up conversations on your code. The Fcc does not wish users of products for Murs to be licensed.

With Murs you can add a larger or external antenna to heighten range. If you want to put an antenna on top of your house or business, you can do it with Murs. Some antenna manufacturers claim an external antenna can growth the efficient radiated power of a transmitter by a factor of 4. These Murs intercoms can forward up to four miles, and perhaps more with an external antenna depending on the terrain.

One benefit of Vhf wireless radios is that battery life is practically all the time great than for similar Uhf units. For handheld radios this is a plus.

Vhf tool is normally lower cost for those on a budget. tool can be more prudent than similar Uhf products.

In summary, if you are planning on using your two-way radios mainly inside buildings, then Uhf is likely the best clarification for you. If you are mainly using your two-way radios for transportation outside, then Vhf would be a good choice. Whether radio technology can work for you if you don't indeed have a long range to cover. In that case you may want to choose Vhf for it's lower cost.

newest Generation of WiFi Ip Sip Phones

If you do a crusade on Google for WiFi Ip Sip phones you'll find one of two things. Either the posts contain data about phones that might be advent out soon, with a posting date from 2004, or you'll find posts from citizen that have downloaded applications for their cell phones that allow them through their capped data plan to make VoIp calls using emulation software. With the improve that WiFi VoIp phones have made in the last two years, it's staggering that there is so miniature written about that most recent handheld hardware.

The Locktek Wp04 WiFi Ip Sipphone is a gigantic step send in movable communications. The phone weights nearby 3oz, has a crystal clear color Tft display and provides standby time of nearby 140 Hours with a talk time advent in at 7.5 hours. The most recent firmware along with dimming of the screen and keypad, as well as the well written firmware growth talk and standby time to levels never seen before. With the Multi-Dialing feature, you can dial phone numbers, Ip addresses and Sip accounts directly. If you have 2 or more Wp04 phones on your local intranet, plainly dial the Ip of the other Wp04 to associate without using a Sip account.

With a Sip catalogue from any worldwide Sip provider, you can make and receive local and international calls from any location with an open or authenticated WiFi signal. I use mine at a local well-known chain donut shop - I walk in, turn on my Wp04 and within seconds I'm connected to their WiFi router. I can check my voicemail and make or receive calls at approximately no cost, depending on your Sip plan. Compared to a cell phone each year plan at .95 a month Plus Taxes, my total VoIp bill last year was , for the Year. We'll talk about multiple inbound phone numbers and costs in a later post.




The Wp04 will store up to 4 Sip accounts, so if you use one supplier for Us/Can calls, other for free inbound like Ipkall.com, and an international Sip supplier for unavoidable international calls, you're covered. You also get Caller Id, anonymous call, missed call indicator, selection of ringtones or vibe alert, a built-in hands-free / mute / earphone mode (with the included earphone/mic), g711 / g729 and g722 (Hd Voice), a WiFi site crusade which shows you which access points are reachable in your area with their reception strength and if they're locked or open, as well as menus in 6 languages.

I've found with the amount of open and available WiFi access points in my area together with libraries, coffee shops, fast food locations, book stores and municipal WiFi (available in many cities across the Us, Canada and worldwide), I've found that I can be in touch with my friends, house and workplace wherever I am. I never miss a call thanks to voicemail, and sound potential compared to Am Radio (cell phone) is staggering using g711 (Fm/Cd quality) with the Wp04. citizen on the other end will hear you as if you were on a landline. Since the Wp04 uses programmed dedicated VoIp Sip chips, there is no emulation, so even in crowded Muni-Wifi or airport WiFi locations, call get through and sound great on both ends.

The Wp04 is available now from Yippz.com and includes all you need to be up and running. If you've already got a Sip account, you're ready to roll when the phone arrives.

Compared to the WiFi phones that arrived on the market over last past some years, there is nothing that compares to the Wp04 on price, size, features and reliability.

Cell Phones - Some Considerations of the Cell Phone of the Future

Cell phone technology has been moving forward at break neck speed, and sometimes we may not notice it, but think back to just a few years ago and you can see all the new feature integration and race in the marketplace - a race to "wow" consumers and get them to choose a specific device. But before we talk about the current trends in cell phones and smart phones, let's discuss the past evolution of these devices.

Since, I had one of the first mobile "cell" phones - I'd like to tell you a quick story to start out this discussion.

Wireless Network Repeater

wireless network repeater

My first cell phones were state-of-the-art at the time, but if you saw them today, you'd laugh. One of them I actually kept; a Mitsubishi Transportable. This phone is about the size of a six pack cooler that you might take to your child's soccer game, and it was quite heavy, as I recall it is well over 10 pounds. This of course included the battery pack to power up to 3 Watt phone.

Remember that Ion-lithium batteries at the time were just coming off the assembly lines and were quite expensive - they did not exist in this size for anything but NASA and military usage. These original cell phones I had were nickel hydride powered, quite an inferior battery technology for modern cell phones.

The Mitsubishi Cell Phone has a strap on it so you can carry it like a purse, and I often felt really stupid carrying it, until of course it rang, and I unzipped the top, pulled out the handset on the phone and began talking. I can recall that everyone stared as if I was a secret CIA agent, was working for MI6, and my name wasn't Lance, it was really James Bond. You see, at that time not very many people had the cell phones and they were very expensive.

Another one of my first phones was a Audiovox 1000 model, which was quite large and it was mounted in my car, a car phone - cell phone. The box that ran the Cell Phone was mounted under the seat, and there was a cradle that held the headset. The headset had a cord on it just like a phone at home, before the cordless phones that is. Under the seat the box was about 3 1/2 inches high and the size of a laptop with a 17.1 inch screen.

This Cell Phone or car cell phone was wired directly to the battery with a couple of fuses. When I turned on the vehicle, the Cell Phone would automatically turn on. If I turned off the vehicle, I had to leave it on accessory with the key in the right position, unless I left the phone on which by-passed the ignition. When the phone rang and actually honked the horn, which got me into trouble a couple of times when the horn went off while I was driving behind a police car stopped at an intersection. I have a lot of stories to tell you about all those early days with the first cell phones, and you may e-mail me if you are ever interested in such experiences.

Folks today take all this for granted, as they don't realize how cumbersome the original cell phones were, or how stupid they were compared to modern day smart cell phones. Today they give you a free cell phone when you sign up for service - back then you had to pay 00 for a car cell phone, and as much as a couple hundred dollars to have it installed. It was quite a procedure, if you have a stereo system, and an XM radio put in your car at the same time, that is about how much work it took to do this. Therefore, at today's labor rates you could easily pay three or 0. That's definitely something to think about.

If I was talking to someone on the phone while the engine was running, if I turned off the car and moved the key to the accessory position I would dump the phone call, as I cut it out during that transition. However, having a cell phone in my car helped me increase my business. At the time I was only 17 years old - I had an aircraft brokerage firm and aircraft finder's service and I would work off of fees whenever an aircraft that I represented sold. I also had a small aircraft cleaning service and was able to contact customers from my vehicle on the flight line, and my crews could call me when they were done with the job as they would use the local payphone to call me.

Thus, this mobile technology allowed me to make more money, and remain more efficient than the competition. Remember at the time this was leading edge technology, it was state-of-the-art, and I had it - the competition did not. No longer was I stuck in an office, I could run my business from anywhere and it allowed me much freedom. Often people today do not realize what it was like before mobile cell phones. Anyone who is in business now over the age of 50 certainly realizes, because they remember a time when there were no cell phones.

This was a period in our nation's history where there were pay phones in every shopping center, every gas station, outside of every fast food restaurant, and people used them all the time. Business People who didn't smoke filled their ashtrays with coins so they can stop and use the pay phone. Thus, allowing them to call clients, customers, vendors, and maintain their operations in the office. When cell phones first came into play they displaced the old Motorola technology of push to talk phones, which worked off a mountaintop repeaters, these phones were very big in the military, construction industry, and all the executives with large corporations had them.

Since this was radio technology, they worked farther than the first cell phones which had to be within 10 to 15 miles of a cell tower. Today, the cell phones are less wattage than they were back then, so the average cell tower is 6 miles or less apart. Back then the cell phones worked off three Watts, and now with 3G technology the wattage is under 1 W. This is probably good for the human biosystem, as it is putting less microwave frequency radiation into your brain, there will be fewer brain tumors, brain cancer, and other issues. There have been many studies including several with the Swiss researchers which seemed to indicate that the 3 W phones were quite unacceptable for human health, and they would slowly cook your brain as one researcher said.

Luckily, for the cell phone industry they were able to bury most of these problems and objections, as well as the studies that the Swiss did. Although, there were studies here in the United States, you would be hard-pressed to find those research studies and data on brain tumors, brain cancer, and their relation to the cell phones that people used. In fact, if you go to Google Scholar today you will be hard-pressed to find anything that would suggest that the cell phones could cause such horrible conditions. This of course is all still up for debate, but we try not to talk about it.

Perhaps, by going to 3G wireless, and lower wattage the mobile cell phone industry dodged a bullet of huge class-action lawsuits, and we may never know the damage we had caused. Nevertheless, as we talk about Six Sigma efficiency in corporations, or using modern management techniques in small businesses, no one can deny that increasing communication speed and reliability is by far a factor in the increase productivity in the 80s and 90s due to cell phones.

At the time I was literally running 1000 to 1200 minutes per month and although that service was much cheaper than the other choices such as the Iridium Satellite Phones, non-cell phone mobile units, as they did not use cell towers, rather satellites - you can imagine the costs of the original cells. They did not have an unlimited plan and once over your minutes, you paid the premium for each minute on that cell phone, my bill was usually 0 to 800 or more.

The other mobile phones at the time were not cell tower-based phones, they were push-to-talk and came in a brief case - it was considered quite James Bond at the time. And this was back in the 1970s, and I remember this, because I started my business when I was 12 years old washing airplanes at the local airport. Many of the businessmen who owned corporate jets had these types of phones. They were basically for the rich and famous, and business person. They didn't work everywhere and you had to have pretty much line of sight to the nearest tall mountain, and that mountain had to have a repeater on top of it, which was hardwired into telephone lines, and the rest of the system worked with ground lines.

All this is very interesting, and we must consider that many folks today have never been alive when there were no cell phones. They have no clue how hard it was to run a business back in the days when there really was no mobile communication. The same repeater systems on top of the mountains that Motorola owned or which used Motorola hardware, also controlled the pagers. These pager systems were quite popular with people on call, such as doctors, and service personnel. Two-way radios, which work basically the same as the two-way push to talk briefcase phones, were used through a dispatcher for companies very often.

Later, just as cell phones came into play, someone came up with the idea of 1.5 way and two-way pagers. Instead of a one-way pager, someone who had what they call an "alpha mate" device could page someone and ask them a question (using a text message) on that page and the recipient could press a button for yes or no, Y. or N. and that information would be relayed to the dispatcher. People actually got pretty good at communicating this way. And you could send text type messages for the user of the pager to read. In reality these were the first text type messages, so the concept of having a mobile device and using text messaging is not all that new.

Two-way text messaging via cell phones is merely a re-introduction of that similar technology. Once people had cell phones they didn't need to use the text pagers anymore, and that technology was leapfrogged as the price of the cell phone services was lower, as competition increased between companies like Sprint and AT&T. There were many other regional smaller players, but they eventually got bought up by the big boys.

The cell phone industry grew so fast in the late 80s and early 90s, that eventually there was coverage everywhere. Then something really weird happened, the promise of 3G wireless came into play, and folks started switching to that new system. I can tell you this - my first cell phones were much more powerful and worked much better than the cell phones of today.

Occasionally, I had a call dropped and there were not as many service areas, yes there were more dead zones, but the signal was much more powerful because it was 3 W, and since it ran off my car battery or a large battery pack in a small carry case, it had ample power to maintain that strong signal.

Today, when I use my AT&T cell phone, I am often cursing because the service is so bad, I wonder why I am even paying for it. In fact, the loss of productivity from dead zones, and the cell phone calls dropping, I feel as if AT&T should be paying me. Apparently, I am not alone many people feel the same way. Nevertheless, the 4G wireless is on the way and everyone will be switching to that so that they will have Internet access allowing them to do e-mails, twitter, video, and real-time text messaging without the use of ground lines

A good many folks do not know of a time when there was no email or internet. And most people who are in business today, who are under 50 years old do not remember a time when we didn't have fax machines, the reality is that fax machines came into play about the time of the first cell phones. Mind you, there was still no Internet, no e-mail, and although ARPANET was being used by the military, and by think tanks, research centers, and top universities, it wasn't really available to the public in the way we have it now.

Fast forward to today and now no one goes anywhere without a cell phone. Social researchers have noted fewer people wearing wrist watches. They don't need a wristwatch because that is a standard feature on all cell phones now. Of course, this doesn't help companies like Rolex who are catering to the young up-and-coming BMW crowd, if you look around you will see that most young executives don't even wear a watch and most of our younger generation doesn't wear a watch either.

It seems that the wrist-watch replaced the pocket watch, and the cell phones seem to be replacing just about everything. These days people use their cell phone or smart phones to do their e-mails, and these same phones act like a PDA, no one carries day planners anymore, although a few people do, myself included perhaps out of habit from using a day planner from the time I was 12 years old in my business until I was in my mid-40s. Perhaps, I am giving away my age, but sometimes old habits die hard.

Today with many laptop notebooks, PDAs, and smart phones, it seems none of that other stuff is needed. Including your human memory say many psychologists, who argue that this technology is causing the human brain to rewire itself differently because there are different needs to get along in the world. After all, all your best friends are on the speed dial and you don't have to remember phone numbers anymore. And all your contacts and information is on your smart phone, in your e-mail program, or on your laptop.

Cyber security analysts worry that if the system crashes or God forbid an electro-magnetic pulse, neutron bomb, or nuclear device is set off high in the atmosphere it could destroy all the electronic equipment, including all the cell towers, your laptop, your television, your refrigerator, and your smart phone. Where will you be then, and can you rely on your memory and the brain you are born with to carry on your daily endeavors - scary thinking, but perhaps we need to address this as we consider the evolution of cell phones.

Today, our cell phones have changed the entire dynamics of our society. There are unspoken etiquette issues of cell phone use in public. There are rules when we can use our cell phones and when we can't. Issues such as driving with a cell phone and the number of auto deaths which occur while people are driving and talking on the phone at the same time. There have been major disasters caused by texting while driving a bus or conducting a train.

The reality is that as our technology has evolved, it is evolving much faster than the human brain can to take it all in. Due to the multitasking required in our society to get along and the high pace and productivity that jobs require, many brains cannot cope or adapt fast enough. And this seems to be a problem, if some people are not able to make the switch, but they attempt to, sometimes while driving with disastrous results.

Our smart phones are becoming super cell phones that have more and more features, such as the ability to store music like the iPod, and vast amounts of data like our electronic PDAs. These devices are getting more high-tech each and every year and they are feature rich. Many have five to ten gigabytes of information storage now. One recent study in the cell phone industry noted that 90% of the people who own cell phones have never used all the features, and do not know how to program them, or even that they exist on their cell phone. Most people don't even care, they use the features they want and none of the others.

This is a common problem with new technologies, and it is something that happened with that Beta and VHS recorders. What's that old joke, there are tons of features on your video recorder at home, but no one knows how to use them, and before we all learned that we need to learn to use these features, the VHS video recorder is out in the new DVDs are here. Now cable companies offer boxes which can record multiple shows so you can watch later or pause a live TV program while you go to the bathroom, or go to the kitchen to get something to eat. Some allow you to use your cell phone to do remote programming too.

These are all things common challenges which are encountered and similar problems with any new personal tech devices which become mass consumer products. Cell phones and our current smart phones are no exception. It's hard to say the future what types of new features in our cell phones will have. The sky is the limit, and the imagination and demand for more features and greater technology is readily apparent. The early adopters of such cell phone and smart phone technologies are willing to spend big bucks to have all-in-one devices. Therefore, these trends will continue.

Just to give you an example of some of the crazy ideas people come up with for future smart phones let me tell you a little quick story.

Our on-line Think Tank came up with a plan to produce a PhD or Personal Health Device, which tracks your diet - on your cell phone. How it worked was quite simple, when you are at the grocery store, you would scan all the items that you bought, and they would go into storage inside your smart phone. Each time you ate one of those items you would simply select what you ate, and punch in the number of servings and you would calculate and keep track of your calories, fat content, and recommended daily allowances in the major five food groups.

The smart phone would have a scanner system on it, later subsequent versions of this smart phone and personal health device would be able to scan products via RFID tags. Your phone could tabulate and even recommend what you should eat, how many more miles you should jog, and what you would need to maintain your diet to meet your personal health goals, and weight loss program. Sounds crazy doesn't it, yes, it does, but the venture capitalists like the idea. So too, do companies that produce high tech smart phones today, as everyone is looking to get a jump on the competition.

GPS systems by way of smart phones or cellular high-tech phones is quite possible (now available), and you don't even need satellites to do it. If you are within the realm of several cell towers your location can be triangulated quite quickly, which pinpoints your exact location within 10 feet. Ah ha, you see the problem in this too; What about privacy you ask? That's a good point and that is another issue that people are quite concerned about with all this new high-tech personal smart phone innovations.

Google Phone and social networking connections appear to be on horizon. That is to say, linking your smart phone with all of your social networking friends, but apparently Google got into a little bit of a problem and noted that many people are not ready for that just yet. In fact, many people who are friends on social networks and make connections, have no intention of ever meeting these people in real life, and therefore they aren't really friends. And since you don't really know anything about those connections or friends on your social networking site, the last thing you want them to do is know exactly where you are within 10 feet.

That should appear to be obvious, and in the future it may not be such a big deal, but people are still a little paranoid and they like to have their privacy. Meanwhile, we read more and more articles about social networking gone bad. That is to say people using social networks to stalk other people, and this also concerns parents who have teenagers, who use social networks on a daily basis, and some that use them on an hourly basis, and a good many who seem to be texting every few minutes.

One recent study of cell phone users was able to have a 93% predictability of where a person might be based on the patterns determined by their cell phone, and when it was connected to any given local cell tower. The study found that most people stay within 6 miles of their homes. These patterns of predictability are a reality in our society and how we operate as individuals - nevertheless this brings up all types of issues that have attracted the attention of the Electronic Freedom Foundation, and it also touches on the issue of privacy and paranoia, it catches people off guard.

Then there is the new trend with smart mobs using their smart phones, and having fun with and meeting up in various places all at the same time. Although these schemes are used for fun, entertainment, and socializing, these same types of smart mobs have the power to destabilize a society or civilization. Consider if you will the use of technology in Tiananmen Square - should governments be worried about your smart phone technology, or the future of 4G wireless cell phones? They probably should be concerned with it, especially if it is used by a foreign government to provide mass protests against what would be a normal stabile government.

In other words it has uses in warfare, the CIA, in bringing down corrupt regimes which are enemies to United States. But rest assured - the same thing could happen in the United States where perhaps a communist rogue nation state decided to have protests in the United States in our major cities on Mayday. It could easily happen especially with our own technology being used against us, due to all the interconnectivity that it offers.

Does this mean that our government has to find a way to turn off all the cell phones in case of something like this happening? Do they need a device to turn off certain cell phones from the system, while leaving first responders cell phones activated for communication? And what about hackers, which might be able to send out tens of thousands of bogus text messages, or call masses of people into a trap, or stage a riot?

These are all questions we need to answer and we need to understand that the same technology we create to improve our productivity, our society, and help us in our daily lives with our families and friends can also be used against us.

And what happens when our smart phones become smarter than us? Some believe, as I do, that they already have. Most of the smart phones today have artificial intelligence systems within them, for instance a text messaging program which guesstimates which keys you are going to press next or what you are trying to say and it offers you suggest is so you can fill in the blank. Making your texting very quick. This is very similar technology that Google uses when doing a search and offer suggestions as you are typing to save you time. This is just one form of artificial intelligence in our smart phones and cell phones today.

There are many cell phones that allow you to use speech recognition to dial phone numbers, search your databases, or navigate the screens on your cell phone. The newest smart phones will be able to tell you when you are in proximity to a Starbucks and then give you GPS directions to find that location. This has big implications for retailers, advertisers, and consumers alike. They will begin to know your patterns and habits. All these technologies are available now and we will see them in the near future. Your cell phone will even become a payment device, hooked to your credit card information. All this technology exists today.

But what about the technologies which are just over the horizon?

We've recently seen at Comdex and CES shows the first generations of projection cell phones, that is to say video conference enabled cell phones which allow you to project to the other party onto the nearest wall or onto a table so you can watch. This will obviously be followed by the Holographic cell phones, which were similar to those that we saw in the Star Wars trilogy.

All these things will be available in the next five years, and you will most likely have them if you buy one of the high-tech cell phones in the near future. At first these technologies will cost a lot extra, but those prices will come down as the number of units built goes up and as more Chinese also purchase their first cell phone, adding another billion people who own such devices, therefore bringing the cost down for everyone - significantly!

By the year 2025 your cell phone will be a brain chip inside of your head, and you can think that you'd like to contact someone and it will dial the number and contact them. By 2050 you will be able to do thought transfer via the small devices, brain implant - perhaps smaller than a dime. And people born after that will never know what time were "thought transfer" did not exist, just like right now there are many people who have never known a time when mobile phones didn't exist. And since Moore's law also seems to apply to the cell phone and smart phone industries we can expect a size reduction as well as a power reduction to run this technology.

In other words, your biosystem will be able to power up your brain cell phone chip, just as it does your current human brain which works on about a maximum of 20 W. of energy, and you will be able to have an eyelid screen, so you can close one eye, and surf the Internet. It's hard to say what the Comdex and CES Show in Las Vegas in the year 2025 will look like, it is probably impossible to pinpoint what these shows will look like in the year 2050. In fact, there may not be shows at all, you may be able to experience these trade shows in your holographic living room, video gaming center.

Walking the virtual halls of the trade show using your avatar and talking to other avatars explaining all the new technologies that are available for you might be the new reality albeit an Augmented or fully Virtual Reality. That appears to be where we are going, although it's hard to imagine considering where we are today. Nevertheless, I can assure you people in the 1950s could not really have imagined the way in which our smart cell phones have evolved in the present period.

Currently, there seems to be a very big push in the larger cities like Atlanta and Dallas, Los Angeles and Seattle, Boston and New York, Miami and Houston towards the 4G wireless, obviously this will continue. That is the full broadband Internet surfing on your smart phone, the ability to watch TV while driving in a car on your cell phone. And next comes the ability to project that TV onto any screen or flat surface that is nearby or available. The technology is getting more robust, it's getting smaller, it's getting smarter, and you have to decide how far you want to go with it.

Perhaps, I should write a quick eBook on this topic and explain chapter by chapter, the evolution of this ominous communication technology, and the future of smart phone personal tech devices. Let me know if you know any interested potential co-authors.

At the current pace we are moving, and at the speed in which we are interfacing with the Internet, social networks, e-mail, and television, it's hard to say exactly what you will be carrying around in the future in your purse or pocket, but I daresay it will be something that is truly incredible, and in the next 10 years it will be hardly imaginable from this point in time to know exactly what it will be, or what it might be able to do. I hope you will please consider all this. And contact me if you'd like to discuss this further at the Online Think Tank.
