Citizens Broadband Radio Service (CBRS) is a 150 MHz wide broadcast band of the 3.5 GHz band (3550 MHz to 3700 MHz) in the United States. [1] In 2017, the US Federal Communications Commission (FCC) completed a process which began in 2012 to establish rules for commercial use of this band, while reserving parts of the band for the US Federal Government to limit interference with US Navy radar ...
Federated Wireless is on the CBRS Alliance board of directors, with director Sarosh Vesuna as the organization's treasurer. [10] The company has worked closely with others in the broadband communications space "to develop standards and equipment to bring the idea to life".

The antenna may not be more than 20 feet (6.1 m) above the highest point of the structure it is mounted to, or the highest point of the antenna must not be more than 60 feet (18.3 m) above the ground (47 CFR 95.408(c)) if installed in a fixed location. [4] CB radios must include AM or SSB modulation and may include frequency modulation. [5]
Networks on LTE bands 1, 3 (LTE-FDD) are suitable for roaming in ITU Regions 1, 3 and partially Region 2 (e.g. Costa Rica, Venezuela, Brazil and some Caribbean countries or territories. Networks on LTE band 20 (LTE-FDD) are suitable for roaming in ITU Region 1 only.
The Primary Rate Interface (PRI) is a telecommunications interface standard used on an Integrated Services Digital Network (ISDN) for carrying multiple DS0 voice and data transmissions between the network and a user. PRI is the standard for providing telecommunication services to enterprises and offices.
Channel-associated signaling (CAS), also known as per-trunk signaling (PTS), is a form of digital communication signaling.As with most telecommunication signaling methods, it uses routing information to direct the payload of voice or data to its destination.
This is a list of telecommunications encryption terms. This list is derived in part from the Glossary of Telecommunication Terms published as Federal Standard 1037C . A5/1 – a stream cipher used to provide over-the-air communication privacy in the GSM cellular telephone standard.
A control channel coordinates all the activity of the radios in the system. The control channel computer sends packets of data to enable one talkgroup to talk together, regardless of frequency. The primary purpose of this type of system is efficiency; many people can carry many conversations over only a few distinct frequencies. [1]
