Recently the introduction of the third generation mobile networks has just been taking place which holds out the possibilities what have never been seen before. Every mobile generation created something new and more valuable for the users in comparison with previous networks and this will be the case also with the appearance of the fourth generation.
As time and the technology progresses, people get used to having access to information at any time, independently of the presence of any cables. Moreover, people want to have continuous high quality services and, at the same time, are unaware of how they will get it and where they are going next. Hence, they need a functioning mobile infrastructure capable of handling high amounts of data. Current mobile standards (the so called "2G", second generation, networks) can be used to transfer data at very limited speed. The recently implementing generation, 3G, will offer better data transfer capabilities, but its speed is still insufficient for many desired applications like video conferencing. Only the next generation, "4G", the fourth generation, will offer data transfer at fully acceptable rate.
However, since the 4G will need to use higher frequencies, it also provides much smaller coverage area per base station. This means, in particular, that while users could enjoy continuous video conferencing, a more complicated infrastructure of service providers has to be set up. Some effort has been done to elaborate on the 4G technical solutions but less on the economical side of this problem.
4G will provide different features like fully packet switching networks, higher bandwidths for providing multimedia services at cheaper rates, higher bit rates approx 100 mega bits per second, very high network security etc. It will have interactive multimedia services such as wireless internet and teleconferencing.
The 4G technology was predicted to become applicable around 2010 but due to so many features and facilities the researchers had put their efforts and by investing $30 billion the technology will be available by 2006, something which has never happened before.
