FAQ's

What is the LTE Radio technology?

The LTE RAT (Radio Access Technology) is based on OFDMA (Orthogonal Frequency Division Multiple Access) enhanced with MIMO (Multiple Input Multiple Output) antenna techniques to increase over-the-air (OTA) data rates.

What is OFDM?

OFDM, also known as Orthogonal Frequency Division Multiplexing, is a modulation method of encoding digital data on multiple carrier frequencies. This is where a significant number of closely spaced orthogonal sub-carrier signals are used to carry data streams. In OFDM a high-rate bit stream is multiplexed into a number of narrow band subcarriers and transmitted over parallel subcarriers which do not interfere with any other subcarrier in the cell. The orthogonality of subcarriers prevents crosstalk between them but it requires strict restrictions of synchronization and low mobility to avoid the Doppler shifting and the subsequent Inter-Carrier Interference (ICI).

How is LTE spectral efficiency improved?

LTE has flexible spectral efficiency, by implementing high Rank MIMO, Higher order Modulation), Carrier Aggregation and using OFDMA on variable spectrum bandwidth (up to 20 MHz).
