What is CBRS?

　　The bandwidth of the CBRS spectrum is 150MHz, and the range of the CBRS spectrum is 3550 to 3700MHz (or 3500MHz to 3700MHz in some definitions), with frequency allocation spanning the existing LTE frequency bands 42 (3400 MHz to 3600 MHz) and 43 (3600 MHz to 3800 MHz).

　　The frequency band of CBRS is Band 48, TD-LTE standard, supporting voice, SMS, and data services. This spectrum is shared and used by the US government, other commercial organizations, and community entities as a shared spectrum.

　　The satellite ground stations and the US Navy have historically held exclusive rights to this frequency band. In 2020, the priority license will be auctioned, allowing licensors (such as Verizon, Comcast and other Internet service providers) to use the frequency band in specific counties in the United States, as long as they do not interfere with the existing frequency band and tolerate the possible interference of the existing frequency band. And authorized access allows other users to use the frequency band as long as they do not interfere with the first two types of users.

　　CBRS overcomes the limitations of WiFi and provides a more efficient option for large commercial enterprises. WiFi coverage and capacity are limited. CBRS provides twice the capacity and four times the WiFi range for commercial enterprises.
