In 2009, the IMT-Advanced (International Mobile Telecommunications Advanced) requirements for 4G standards was made by the ITU-R organization,including top speed requirements for 4G service at 100 Mbit/s for high mobility communication and 1 Gbit/s for low mobility communication.ITU (International Telecommunication Union) regards LTE-Advanced as the authentic 4G standard, at the same time,it also welcomes LTE as a 4G standard. 4G technologies for instance mobile WiMAX has been available for sale since 2006.It is in December 2010 that the ITU declared that WiMax, LTE, and HSPA+ fall into 4G technologies.

Once the Internet Protocol (IP) multimedia sub-system movement accomplishes what it is about to do, absolutely nothing of this possibly will concern. After fantastic implementation, 4G technology is most likely to make it possible for common computing, that will also links to many top date speed networks and affords perfect handoffs everywhere in the geographical regions.
A lot of network operators tend to make use of technologies,for instance,wire free mesh networks as well as cognitive radio network to make sure secure and protected connection & competently allocates equally both network traffic and bandwidth.
Many smart phone handsets operators take advantage of 4G technologies,either. 4G smart phone handsets can be found in many world well-known brands,such as Motorola,LG,Samsung and HTC.
