CBRS Network Architecture: CBRS is known as Citizen broadband radio service, It is a 150 MHz wide broadcast band in  3.5 GHz band starting from 3550 MHz to 3700 MHz. In 2017, the FCC completed a process to establish rules for commercial use of this band. Commercializing this band enables Service Providers/Wireless Operators to use it without acquiring frequency licenses. CBRS frequency spectrum shall help 4G/5G mobile networks deployment quicker and easier. CBRS band is also referred to as 3.5 GHz band. Considering CBRS is deployed with 4G LTE technology, it is very...
