what is LTE ?

LTE will enhance demanding applications such as interactive TV, mobile video blogging, games and professional services.
And in addition to mobile phones, many consumer devices like notebooks, ultra-portables, gaming devices and cameras, will incorporate embedded LTE.
So what makes Long Term Evolution better than current broadband networks?
LTE provides downlink peak rates of at least 100 Mbps. That’s a huge improvement over current networks, which only support downlink speeds of 1.8, 3.6, 7.2 and 14 Mbps, with available speed increases up to 42 Mbps and 84 Mbps.
LTE technology, on the other hand, will allow for speeds of more than 300 Mbps. Sony (NYSE: SNE) has already demonstrated Long Term Evolution peak rates of about 160 Mbps.
LTE also supports flexible carrier bandwidths, ranging from 1.4MHz to 20MHz. Thus, an operator can introduce LTE in new bands where it’s easiest to deploy and eventually deploy Long Term Evolution in all bandwidths.
