LTE can reach 100Mbps downlink speed and upto 75Mbps uplink
speed. It used OFDMA or Orthogonal Frequency Division Multiple Access for
downlink and SC-FDMA or Single Carrier Frequency Division Multiple Access for
Uplink. The base station in LTE is called as eNode B and the mobile station is
called as UE or User Equipment. Downlink is from the eNode B to UE and Uplink
is vice versa. LTE supports multiple bandwidths right from 1.4MHz to 20MHz, it
is this flexibility of LTE that is attracting the operators from all over the
world. The main reason for this is there is a tight lock in the spectrum now
because of so many wireless applications.
