The FCC, in
coordination with the National Telecommunications and Information
Administration and the Department of Defense, on Monday certified that
five Spectrum Access Systems (SAS) satisfied the Commission’s laboratory
testing requirements and are approved to begin their initial commercial
deployments in the 3.5 GHz CBRS band (3550-3700 MHz ). The approved SAS
are operated by: Amdocs, CommScope, Federated Wireless, Google, and
Sony.
The companies will conduct field tests and the Commission will assess
whether each SAS can operate under actual deployment conditions. Each
company must tell the agency when its deployment begins and whether it
will operate with an approved Environmental Sensing Capability. The
notification must include a primary point of contact for incumbent
operators to report potential interference issues to the SAS. Initial
commercial deployments must last at least 30 days and test several CBRS
devices. The companies must report results to the government for final
review. Stakeholders plan full commercial launches to begin in the
fourth quarter of this year.
The promise of the CBRS band is that new entrants will use dynamic
spectrum sharing to co-exist with federal U.S. Navy radar systems
operating along the coasts. Using SAS to let them know when a channel is
occupied will enable new entrants to operate on different CBRS channels
to avoid interfering with naval operations. The news opens the door to a
market opportunity for operators, enterprises and industrial players,
according the CBRS Alliance,
an industry organization focused on driving the development,
commercialization, and adoption of OnGo™ shared spectrum solutions.
AT&T, Charter Communications and Verizon have developed technology
and services to support the use of OnGo. Commercial services are planned
for thousands of sites. Continue Reading
