5G Tech Soars to New Heights
May , 15 2020
5G technology brings high bandwidth, low delays and broad connectivity characteristics. This makes it a key technology for digital transformation for the economy and society. Building the world's highest 5G base stations and bringing 5G signals to the summit of the world's highest mountain is to provide a sound telecom infrastructure for scientific research and environmental monitoring of the peak...

3dB Hybrid Coupler
Aug , 07 2020
The 3dB Hybrid Coupler is also called the same frequency combiner. It can continuously sample the transmission power along a certain direction of the transmission line, and can divide an input signal into two signals of equal amplitude and 90° phase difference. It is mainly used for multi-signal combining to improve the utilization of output signals. It is widely used to combine base station signa...

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...

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...

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 ...

AN INTRODUCTION ABOUT SECTOR ANTENNA
Aug , 21 2021
To increase or widen the coverage area, and thus the number of served clients, several sector antennas are installed on the same supporting structure, such as tower or mast. Such a construction is often called a sectorized antenna, though sometimes for brevity "sector antenna" is used as well. It has several angularly-separated sector antennas.GSM Multi-Band Directional Sector Antenna is one of ty...
