What is CBRS?

Citizens Broadband Radio Service (CBRS) is the 3550-3700 MHZ spectrum band allocated for public use by the FCC. The underlying standards for this three-tiered access system have been developed by the Wireless Innovation Forum (WInnForum), a multi-stakeholder group.

How do we benefit from CBRS Standards?

- Ecosystem Interoperability among:

  • Embedded devices/IOT
  • Smart Cities
  • Private Netwoks
  • Fixed Wireless
  • Neutral Host

Who are the participants in the CBRS Ecosystem?
