What is LTE Repeater, how it works? perfect guide for buying one !

A LTE repeater (also known as cell phone signal booster or amplifier) is a type of bi-directional amplifier used to improve UE reception and address coverage issues. LTE repeater does not just do power amplification of the received signal from LTE eNB or LTE Base Station, it also selects the band specific signals using one duplexer. After amplification it transmits the signal back to…

What is Inter Symbol Interference (ISI) in LTE, How Cyclic Prefix (CP) helps eliminating this problem ?

What is Inter Symbol Interference (ISI) ? In an ideal system (theoretical), the transmitted symbols arrive at the receiver without any loss or interference, as shown in the following figure. But in a real scenario, due to the signal propagation phenomena, such as reflection, diffraction or multipath, a receiver can receive several delayed versions of…
