4G Technology and its predecessors 3G, 2G and 1G are all from the same family of cellular communication standards, which are verified by the ITU. The ITU i.e. International Telecommunications Union is established by the United Nation, which administers all the telecommunications matters all over the world. The earlier technologies like 1G and 2G did not able to cope up with the current technologies 3G and the latest 4G. The earlier telephone systems, which were the original ones, are now called 1G. In the year 1991, 2G started to replace the old 1G and was first launched in Finland. The network system of 2G was way more than the 1G, had better radio communication and 2G networks were digital.

3G

After 2G, came the more efficient technology 3G, it established its roots in late 2000, while ITU agreed to the 3G standards in 1999. The Third Generation technology now can easily be found all over the world on nearly all standard radio technologies such as CDMA and the GSM. The first cellular network provider that set up the 3G grid in the year 2003, is Verizon. 3G technology provides up to 2 mpbs data transfer rate at fixed spots (when user is stationary) and minimum 384 kbps when the user is moving. Today almost all the well-known carriers of US provide 3G service and now there are lots of gadgets available in the market with 3G capability.

4G

4G technology, the Fourth Generation Technology, is the very latest and ultra fast technology and it is getting more attention day by day even though this technology is still at its initial stages. 4G technology aims to provide fastest speed to all the users, to the users of mobile or smartphones it intends to provide data transfer rate up to 100 mbps while for its stationary users, it aims to the highest speed of 1 Gbps.

WiMAX and LTE

These are two 4G cellular broadband networks. The WiMAX provides speed up to 128mbps of downloading and for uploading it provides 56mbps, whereas LTE showed in an early implementation speed up to 100mbps downloading and 50 mbps uploading. ITU considers the LTE (Long-Term Evolution) as a standard technology because LTE aims to exceed the specifications of ITU. While WiMAX on the other hand is an IEEE standard, also ITU doesn’t considered WiMAX a true 4G technology because it is not up to the specifications that ITU put forth.
