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...

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 ...

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 active DAS?
Nov , 07 2020
Active DAS An active DAS converts the analog radio frequency transmissions from the signal source to a digital signal for distribution. A master unit performs this analog-to- digital conversion. The master unit may digitize the signal from a single carrier or multiple carriers. Once converted, the DAS transmits the digital signal over fiber optic or Ethernet cables to remote radio units (RRUs) tha...

Your Next Bandpass Filter
Oct , 22 2020
RF Bandpass filters are used in both wired andwireless communications systems, sensor applications, instrumentation, medical applications, and many others. When it comes to these types of applications, the goal is to pass signals of interest from point A to point B, while reducing noise and unwanted radiation from the signal source, other equipment, and the environment. Often different...

How to Grasp Chances to facilitate 5G fast network construction?
Oct , 08 2020
With the rapid development of 5G, the communication industry will usher in a major opportunity for development. Because the existing stock of traditional DAS system in 5G era cannot support functions such as 3.5GHz high-frequency and xTxR MIMO, etc., the evolution to 5G has encountered a development bottleneck. 5G will address the challenge of providing continuous network coverage for a large numb...

Cellular Distributed Antenna Systems (DAS)
Sep , 17 2020
How A DAS Works A DAS is a network of antennas that sends and receives cellular signals on a carrier’s licensed frequencies, thereby improving voice and data connectivity for end users. In its most simplified form, a DAS has two basic components: 1 - A signal source A Distributed Antenna System, as the name implies, “distributes” signal. But it generally doesn’t generate the cellular signal itself...
