How to LTE Radio Air Interface?

The state-of-the-art design of the LTE air interface is characterised by OFDMA (DL) and SC-FDMA (UL) together with MIMO. The downlink modulation is based on OFDMA (Orthogonal Frequency Division Multiple…

How Frame Structure in Wimax ?

The physical frame includes the downlink sub-frame, uplink sub-frame, TTG, and RTG. The physical frame length and the respective duration of downlink sub-frame and uplink sub-frame are broadcast by the…

Ranging in Wimax

The initial range is the process of estimating the distance or propagation time between a transmitter and a receiver. Area information can be used to assist in setting operating parameters…

What is the difference between LTE and VOLTE?

What is VOLTE:- Volte (voice over lte) refers to voice calls made through a 4G LTE network rather than traditional calls made using csfb (circuit-switched fall-back), a system that switches…
