1G (First Generation): Refers to the name given to the first generation of mobile telephone networks. These systems used analogue circuit-switched technology, with FDMA (Frequency Devision Multiple Access), and worked mainly in the 800-900 MHz frequency bands. The networks had a low traffic capacity, unreliable handover, poor voice quality, and poor security.

3G (Third Generation): Mobile telephone networks are the latest stage in the development of wireless communications technology. Significant features of 3G systems are that they support much higher data transmission rates and offer increased capacity, which makes them suitable for high-speed data applications as well as for the traditional voice calls. In fact, 3G systems are designed to process data, and since voice signals are converted to digital data, this results in speech being dealt with in much the same way as any other form of data. Third Generation systems use packet-switching technology, which is more efficient and faster than the traditional circuit-switched systems, but they do require a somewhat different infrastructure to the 2G systems.
4G (Fourth Generation): As the limitation of the 3G, people are try to make new generation of mobile communication, this is the 4th generation. This 4G system is more reliable, fast and easy.

Technological Development of Handphones
Ok, so from what I've written above, we learn that handphones just keep getting better and better. Compared to the very earliest chunky walkie-talkie one and the slim beautiful sexy ones we have now, you can see (a gigantic) difference in the design, technology and so on~
Bluetooth, a form of wireless short range connection also changed the way mobile phone operates. Bluetooth is co-developed by mobile phone developers such as Sony Ericsson, Motorola, Nokia and some computer/electronic developers.
Mobile phones can also become an information centre. Information from weather reports, latest news, share market status etc can all be gathered from small mobile phones. Before WAP or GPRS were well developed, users can gather the above information from the system operator (depending on the system operator, not all provide these services).
How Handphones Work
Here is a diagram that shows how handphones actually work, followed by a nice video, just in case you got lost~ ^^(Source: consumerreports.org)

For example, on emergency, you are looking for the nearest public toilet, the mobile phone can identify your location via GPS, and direct you to the nearest LOO.
Phones with Wi-Fi features enable the user to access the Internet, read emails, send replies and surf the Web while on the move. For dynamic and fast changing information such as Forex Exchange Rates, Stock Exchange Reports, share prices and company search are all available on the finger tips so to speak.
