dB commonly known as decibel, deci can also indicate to one tenth.It is a unit of Power Gain, in the units of 10lg, it shows a relative value.10 lg A/B is a unit for counting, it can be used in calculations, for solve how many dB has power A gain or loss than power B. For voltage or electron current, dB = 20*lg(A/B). In other words, a dB is to facilitate an enormous number (positive or n……
CBRS is the short for Citizens Broadband Radio Service. In 2015 the US Federal Communications Commission (FCC) approved the spectrum for CBRS (Citizens Broadband Radio Service). The bandwidth of the CBRS spectrum is 150MHz, and the CBRS spectrum ranges from 3550 to 3700MHz (or 3500MHz to 3700MHz in some definition), with frequency allocations spanning the existing LTE Band 42 (3400 MHz to 360……

On September 22, Beijing time, Comcast, the largest radio and television cable network operator in the United States, announced that it will build its own 5G wireless network, which will adopt two major frequency bands, one is the CBRS frequency band, and the other is the 600MHz frequency band.This makes Comcast the first broadcast and cable TV network operator in the world to build a 5G wireless ……
In the last article, we introduced that the development of microwave communication systems has also undergone analog-to-digital conversion like other radio communication systems.Each transceiver of the analog microwave system can work in 60-channel, 960-channel, 1800-channel or 2700-channel communication, and can be used for microwave circuits of different capacity levels. But due to technological……
Microwave is a transmission method of communication. For digital microwave communication technology, microwave is used as a way to complete the transmission of digital information. At the same time, through the use of radio space, it is possible to transmit all kinds of irrelevant information. Up to now, digital microwave communication technology has become a widely used technology. The technology……
