Long Term Evolution Network. Also known as 4G LTE Data and Evolved Universal Terrestrial Radio Access (E-UTRA). Data service for wireless consumer devices.

LTE uses OFDMOrthogonal Frequency-Division Multiplexing (Orthogonal Frequency Division Multiplexing) modulation. In a LTE channel, it is divided into resource blocks. Each resource block is 180kHz in bandwidth. In each of the resource blocks, there are many subcarrier channels which are spaced 15kHz away from each other.

For a 20MHz channel, there could be up to 1024 subcarriers. The high number of subcarriers will allow for more users to use the network simultaneously.

Modulation[edit]

  • Orthogonal Frequency Division Multiplexing: Quadrature Phase Shift Keying (OFDMOrthogonal Frequency-Division Multiplexing-QPSKQuadrature Phase-Shift Keying (2 bits per symbol))
  • Orthogonal Frequency Division Multiplexing: Quadrature Amplitude Modulation (OFDMOrthogonal Frequency-Division Multiplexing-QAMQuadrature Amplitude Modulation)
