There is a range of varying wireless communications which exist:

1. Specialized mobile radio and land mobile radio, as used in certain industrial situations and by public safety personnel.

2. Citizens band radio, a two way system established for consumer use.

3. Amateur radio enthusiast bands, also known as ham radio.

4. An increasingly large number of car and trucks use a global positioning system (GPS), a technology that has also been favored by ships captains and aircraft pilots for many years now.

5. Within a home or office environment, numerous cordless peripherals exist. For example, your computer mouse or your printer, linked by wireless means to the main computer.

6. To the benefit of the active mom, the cordless telephone is an excellent example of a limited range wireless gadget.

7. Probably the best-known example of wireless communications technology in action is the cellular telephone which, like a pager, provides active connectivity to billions of people worldwide as an integral part of their active personnel or business life.

There are three different types of wireless communications technology which includes radio, microwave or infrared frequency. To convert these forms of communication, we find point to point, broadcasting or cellular networks.

The last 20 or 30 years have seen a dramatic advancement in the field of wireless communications technology, following on the heels of amazing scientific innovations. Who could imagine that we would be seeing such incredible flexibility in our personal and professional lives?

As of recent times, wireless communications technology is the best example of the cell phone. Telephone sets are connected with nearby service points through radio waves. The service site receives and transmits signal, whilst voice and data are exchanged.

Numerous cell sites or transmitting towers are required and these vary in size and distribution according to the density of population; for example, in rural areas they are normally few and far between. The sites are linked to exchanges and connected to the bigger network.

Cell handsets and sites can continuously change frequencies as per the sophisticated procedures and equipment. Multiple usage and low interference rates are achieved through the use of low-power transmitters.

The current high level of wireless communications technology allows for the existence of a number of different digital cellular options. With stiff competition and constant innovation, we can be assured that consumers will be able to continuously enjoy the technology of tomorrow, in the present.

There can be little doubt that the “wired” world will eventually be replaced almost completely by the freedom of wireless. We will be continuously and fully connected irrespective of what we are doing and where we are.

While you might like the phone, you may not like the provider; in such a situation you need to know how to unlock the phone before you can actually change over to another service.

Whilst a traditional cell phone service works by sending calls to a phone, which retains its own unique serial number, a GSM mobile phone is very different. This phone uses a removable memory card or account card which is also known as a SIM card where SIM stands for “subscriber information module”. It is the card which identifies you to the service provider, as it has its own unique serial number.

Sometimes, you can simply transfer your SIM card to any other compatible GSM mobile phone, enabling that phone as your point of contact. The service provider will simply look for your SIM and find you. So you can continue using the same carrier by transferring your SIM to an appropriate enabled phone which you like or you can keep the phone which you like and change to another provider by inserting the specific SIM.

GSM is simply a type of digital mobile phone service, which is prevalent worldwide. On the other hand, within the USA, only specific carriers feature this particular type of technology, although this group does include a quite a few of the major carriers.

You may well find that your GSM mobile phone is locked and in this case you will have several questions. Is it legal for me to unlock my phone? Will my existing provider know if I unlock my phone? Can my existing service provider relock my phone without telling me?

As far as legality is concerned, unless your specific service contract dictates that the phone remains their property and that you will not modify it, then you are in the clear. It seems unlikely that your carrier will know if you unlock your phone or not, and it appears that they are not actively checking via electronic means.

Most GSM mobile phones can be unlocked. There are a couple of different ways to go about this. Sometimes you will need a secret code and there are a number of websites online that can provide you with a secret code for most models of cell phone.

Some types of phone require that their operating system software be rewritten. Again, there are companies out there who will connect your phone to a special programming unit to facilitate this.

The GSM mobile phone is increasingly popular in the United States and represents the lion’s share of units in Europe and elsewhere. Following a simple procedure you should be able to ensure that you can keep a phone that you particularly like and transfer between certain providers by unlocking its potential.

In the world of wireless cellular phones, there are basically two major and competing networks. These are GSM, which stands for Global System for Mobile Communications and CDMA, or Code Division Multiple Access.

These technologies are used by the various cellular carriers to provide service to the consumer. Each network is distinct, but as time goes by they are changing and acquiring characteristics that make them, in many cases, indistinguishable. Proponents of either architecture claim that theirs is superior, but it is important to understand and compare both technologies.

GSM is the older technology, insofar as it has been around since 1987. CDMA was developed by QUALCOMM in the United States and has become the more dominant of the two networks in North America. Both GSM and CDMA networks continue to make inroads into each other’s territories. It should be noted that GSM still retains the lion’s share of the worldwide market and its very strong presence in Europe has catapulted it to 73 percent globally.

There are a number of things to bear in mind when comparing the two networks. Firstly, of course, you need to check service and coverage in the area that you will be using your phone. As mentioned, GSM is far more widespread in Europe, CDMA not so much, but in many cases, the coverage areas match up.

These days, cell phones are expected to also act as streaming video devices, podcast receivers and e-mail devices, so data transfer speed is becoming very important. Both technologies boast third-generation capabilities or “3G” as it is more commonly known. There is a lot of cutting edge activity here, with GSM and CDMA networks vying for position. Each technology claims stellar downstream transfer rates, but specially enabled phones are often required for compatibility.

For a while, GSM retained the edge with their subscriber identity module card also known as SIM, which can be activated, interchanged, swapped and upgraded without carrier intervention. Now, however, CDMA has an R-UIM card, slated for the United States market, but until then CDMA phones in the United States are carrier specific and may not be enabled through a card. When it comes to roaming, concentration of coverage is fairly well established, although GSM seems to have the edge and CDMA charges are generally higher when it comes to roaming in more rural areas.

GSM carriers offer an advantage when it comes to international roaming. For example, you can use your GSM cell phone abroad if it is quad-band enabled and you can also purchase a special SIM card allowing you to make calls without incurring international roaming charges.

Even though customers of GSM carriers outnumber those who use the CDMA network by about four to one, the advent of the CDMA SIM-card equivalent and the improvement of roaming contracts between networks means that the difference between GSM and CDMA networks will soon be erased.

Within the United States, the major carriers are pretty evenly split between the GSM and CDMA networks. The good news for the consumer is that as the CDMA evolution gathers speed, we can expect more choices, more flexibility, more cool features and more freedom.

Second-generation advancements emerged in the 1990s when two separate digital voice standards emerged. These competing standards were CDMA – or Code Division Multiple Access – a standard which was able to multiplex up to 64 calls per channel in the 800 MHz band and GSM – Global System for Mobile Communication – which was able to multiplex 8 calls per channel in the 900 and 1800 MHz bands.

Up until very recently, these two technologies existed in parallel. CDMA was mainly adopted in North America, whilst GSM found more of a global adoption. Technological advances within each system continue to narrow the differences between both. For example, CDMA is now introducing a “SIM” card equivalent, catching up to a valued and well-established feature of the GSM network.

3G, third-generation protocols support much higher data rates, measured in Mbps, for non-voice applications. The technology has been under development since its introduction in 2001 in Japan and its arrival now means that 3G cell phones come equipped with full motion video, video conferencing and full Internet access.

As the new 3G technology was quite revolutionary, engineers and developers had to make some evolutionary upgrades to the existing networks to allow for its deployment. Two distinct families emerged – 3GPP and 3GPP2 – and thus 3G cell phones were born.

3GPP and 3GPP2 continue to evolve during 2009. Complex services and standards are being developed and we can be sure that the latest 3G cell phones represent the cutting edge of what is available today. Indeed, some are referring to certain current advances as heralding the emergence of 4G, or fourth generation, but this assertion may be a little premature.

What seems certain is that 3G cell phones represent a quantum leap forward in the science and technology arenas. Your new cell phone will now become a far more useful and versatile tool. These latest advances continue to point towards the development of the cell phone as an essential, all-encompassing and comprehensive communication device for the future.

A mobile phone can be regarded as a very high-tech radio based device. It’s basic structure resembles that of a walkie-talkie and a CB radio. But we must not forget that CB radio or walkie-talkie is device of a simplex system in which one person at a time can talk or listen.

A mobile phone is a dual mode device in that a user and talk and listen simultaneously. A mobile phone in essence and give and go with a signal at the same time. There are two different channels or frequencies that allow information to flow in two directions at once. You can communicate on 1664 channels in a mobile phone but in CB radio only 40 channels are used.

The slang term for a cellular phone is a cell. It’s technical term is actually mobile phone. Its working protocol is based on division of an area. The whole network area of the provider is divided into small cells or areas. In this network each cell or area has an antenna. Whenever a person along with a cell phone enters within the network area, the cell phone tries to keep a contact with the local antenna. Thus it is truly known as a cellular phone.

A cell phone retrieves its unique code from its service provider. This code distinguishes the cell phone from others and helps in identification. A series of events takes place whenever someone tries to make a call from the cell phone.

Whenever you switch on the cell phone it seeks for a system identification code to identify uniquely the provider on the control channel. This control channel can be a special frequency, which is used for the purpose of talking. Whenever the phone can’t find any control frequency it sends out a no service message.

When your cell phone gets the desired frequency it matches it with the system identification code which is programmed in to the phone. Then the GPS system and all of it’s related programs can track down your phone, locate it’s exactly location, and let’s you know where your phone is located. After receiving a call this office searches into the database to locate your phone and identifies the cell you are using.

Voice over IP (VoIP) provides better service because it has greater bandwidth efficiency that allows for a higher quality of voice and data transmission. Rather than the traditional public switched telephone network used with landline phones, VoIP transmits voice, voice messaging, facsimile and other communication services via the Internet.

Unlike traditional copper wire phone systems that use an analog voice signal, Internet Protocol (IP) converts analog to a clearer, faster, digital format. Digital provides better quality and service and, because its signal can be compressed, it can perform a great many more communication functions.

Because voice over IP uses one infrastructure for both voice and data, it can provide better and more enhanced service at a lower cost. A main reason why costs are cheaper is because Internet access is billed per megabyte rather than per minute or per second like regular phone calls. As such, the cost for data transfer is much less than that of time connected.

Telephones that use IP technology are much more economical, with the best deals providing unlimited inbound and outbound telephone calls to anywhere in the world for one low, monthly price that is all inclusive.

This technology also offers many more capabilities than phones using a public switched telephone network. Among them are broadband Internet access, email, texting, video conferencing and faxing. You can even watch TV on your phone.

All the benefits of traditional phone service is available with voice over IP, including call forwarding, call waiting, caller ID, automatic redial, IVR, call blocking, speed dialing and conference calling. However, these services are enhanced with additional convenient features.

For example, voice mail is improved because it can be accessed from your phone, email, or Web browser; incoming calls can be forwarded to as many as five different numbers; telephone conversations can be recorded so you can save important information; and call broadcasting can send information to 30 people at one time.

Voice over IP is available on landlines and mobile phones. Any type of calling can be done, including local, long distance, roaming, international and mobile. VoIP continues to grow in popularity because of the wide range of services it can provide. It’s fast, efficient and reliable. VoIP also taps into wireless technology to provide even greater mobility.

With voice over IP, better capabilities are realized. For instance, the technology can transmit numerous telephone calls over the same broadband connection, so it’s less costly to add additional phone lines to a home or business. In addition, obtaining a secure telephone connection is part of VoIP standard protocols. Another benefit is that local phone number and mobile phone number portability when changing carries is also possible with VoIP.

Since IP protocol services both a standard telephone line and a broadband connection, savings can be realized because you are receiving both capabilities in one price, rather than paying separately for them.

Using this enhanced VOIP cell phone technology, there’s no longer any need to pay separately for phone service and Web access no to pay for roaming charges or long term contracts that charge you an arm and a leg to make international mobile phone calls.
