Cellular Technology

Cellular Technology refers to a wide range of technologies for transmitting voice and/or data over a cellular network. Implementations include 

• GSM/GPRS
•  CDMA
•  HSDPA, and other technologies.

Cellular technology is the technology used for cellular communication.This technology is widely used in applications such as remote data collection, remote voice communication, and other mobile or remote devices. The increasing capabilities of cellular devices are allowing this technology to be integrated into more applications. Since the start of this millennium, a standard mobile device has gone from being no more than a simple two-way pager to being a mobile phone, GPS navigation device, an embedded web browser and instant messaging client, and a handheld game console. Many experts argue that the future of computer technology rests in mobile computing with wireless networking. Mobile computing by way of tablet computers are becoming more popular.

                  

Cellular technology  is based on radio technology that was developed from the 1940’s onward. For instance, the beginning of cell phones can be traced to the innovations in taxi cabs & police cars where radios allowed taxi drivers or police officers to communicate with one another or with a central base.

The Swedish police used the first official mobile phone in 1946. The phone was not very practical as it could only make 6 phone calls before the car’s battery was drained.

 Later on, another engineer from Bell Labs came up with the idea of cell towers. However, although some technologies had been developed, electronics and other technologies take decades to mature. For instance, the electronics that were used in the first cell phones were first developed in the 1960’s.

By 1967, mobile phone technology was available but the user had to stay within an area.While the technology had been developed, it  took more than 10 years for an approval.

Throughout the decades, many technologies that made mobile phones available existed. These phones were installed in vehicles due to the large battery requirements. 

In 1983, Motorola unveiled the first truly portable cellular phone to the world.The DynaTAC800X was extremely lightweight for its time and only weighed about 28 ounces.

Cellular phones from the early 1990s are considered second generation (2G) . 2G mobile phones use digital circuit switched transmissions. This enabled quicker network signalling, lowering the amount of dropped calls and increasing call quality.

Phones based on 2G technology were much smaller than the brick telephones of the mid to late 80s. Most 2G cellular phones were usually in the range of 100 to 200 grams, plus they were hand held devices that were truly portable and did not need a large battery. Advances in battery and computer chip technology also helped to make 2G cell phones much smaller than their predecessors. With these innovations, cell phone use soared.

Third Generation cellular phones is the technology that is currently available and it is commonly referred to as 3G. While 3G came only a few years after 2G, mainly due to many innovations in technology and services, standards for 3G are usually different depending on the network.

 There are two main requirements: they include 2 Megabits of maximum data rate indoors and 384 kbits for outdoor use. 3G mobile phones usually include innovations to receive much more than phone calls. For instance, SMS text is available and some 3G phones also offer email and Internet access. Technologies are continuing to improve and new innovations such as streaming radio, TV, as well as Wifi are currently breaking into the market.
