Distributed antenna system
Nov , 26 2020
A distributed antenna system, or DAS, is a network of spatially separated antenna nodes connected to a common source via a transport medium that provides wireless service within a geographic area or structure.DAS antenna elevations are generally at or below the clutter level, and node installations are compact. Adistributed antennasystem may be deployed indoors (an iDAS) or outdoors (an ...

What is Hybrid DAS?
Dec , 12 2020
A hybrid DAS A hybrid DAS combines characteristics of passive parts(including RF antenna, directional coupler, power divider,hybrid coupler)and active systems. The RRUs are separate from the antennas, allowing the system to use both fiber optic cable a configuration includes an RRU on each floor that converts from the digital signal to analog RF. The analog RF signal is then connected to multiple ...

Radio and Television anti-5G interference solution
Dec , 15 2020
Radio and Television anti-5G interference solution The 3-5G of 5G will cause serious interference to the reception of c-band (mainly 3.7-4.2g) broadcast and TV satellites.According to the equipment composition of the satellite receiving system, the equipment used at the present stage (common C band LNB operating band 3400MHz -- 4200MHz) and the frequency range used by 5G base station (3400MHz -- 3...

Coverage vs Capacity
Jan , 23 2021
Coverage vs Capacity To be able to compare the different technologies, we need to review the two main performance reasons that DAS solutions are deployed: to provide coverage and capacity. Some locations experience significantly more cellular data usage than others. Think of a sports stadium hosting the Super Bowl, or a large music venue hosting Justin Timberlake. If the venue relied on a ne...

POWER SPLITTER – RESISTIVE, REACTION, AND WILKINSON
Mar , 01 2021
Power splitter, also widely known as Power Divider, is a device that divides a radio frequency microwave input signal into any number of output signals and while doing so, it maintains the characteristic impedance of the input. They are widely used in labs, radar and communication systems and test instrumentation etc. They are categorized broadly into two- Resistive and Reactive. Resistive Power S...
