Distributed Antenna System (DAS) Concept, Its Types and Benefits
According to the DAS Forum Definition, a Distributed Antenna System, or DAS, is “a network of spatially separated antenna nodes connected to a common source via transport medium that provides […]
What is RRH (Remote Radio Head), How it is connected to BBU (Base Band Unit) ?
The remote radio head (RRH) contains the base station’s RF circuitry plus analog-to-digital or digital-to-analog converters and up/down converters. It is sitting on top of cell tower that mainly performs […]
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 […]

What are E-UTRA Test Models (E-TM) in LTE ?
The E-UTRA test models (E-TM) are set of signals defined by 3GPP for the radio frequecy standard testing of LTE device (it may be eNodeB or UE) transmitter chain. The […]
What is PAPR (Peak to average power ratio), Why it matters to Power Amplifier ?
The PAPR is the relation between the maximum power of a sample in a given OFDM transmit symbol divided by the average power of that OFDM symbol. In simple terms, PAPR […]
