Three GPP (3GPP) Long Term Evolution (LTE)
Long Term Evolution (LTE) is the next-generation high-performance communication interface for cellular mobile technology. It is the project of the 3rd Generation Partnership Project (3GPP) . LTE is marketed as 4G, which provides improved bandwidth, lower cost of ownership and enables many multi-media services. LTE theoretically can offer up to 326 Mbps in the downlink and up to 226 Mbps in the uplink with 20MHz 4x4 MIMO antenna [2, 3]. The recognized sector data peak rate as provided in  depends on the frequency spectrum bandwidth used. According to , LTE has capabilities to be deployed in clear spectrum with bandwidth as high as 20 MHz. The high bandwidth of a single carrier radio will allow scope for significantly larger coverage capacity and ability to support a higher number of points compared to 3G-3.5G technologies attached to the 5MHZ or smaller spectrum bandwidth.
Nortel  summarizes features & benefits of LTE as follows:
LOWER TOTAL COST OF OWNERSHIP
LTE can serve as a communication platform for sending energy data from customers' meters to utility companies.
