BASE STATION antenna-sector antenna
Mar , 20 2021
As known that inbuilding solution wireless coverage will use omni ceiling antenna, directional coupler, 3dB hybrid coupler, power divider splitter and panel directional antenna. and where is this original signal from? There the base station comes, and one kind antenna is used very frequencly at base station. In the engineering design of mobile communication network, the base station an...

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...

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...

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 ...

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...

Public Safety Distributed Antenna System (PS DAS)
Jan , 09 2021
A Public Safety Communications system is a wireless communications system used by first responder and emergency services personnel such as police, fire, emergency medical, homeland security, and disaster response agencies to prevent or respond to incidents or situations that pose a threat to people or property. Bands of frequencies, especially in the VHF and UHF parts of the spectrum, were allocat...
