CBRS management.

In order to take advantage of CBRS, your network must employ a Spectrum Access System (SAS) and have access to an Environmental Sensing Capability (ESC) network to dynamically manage the spectrum use.

The Spectrum Access System (SAS), is an automated frequency coordinator that manages spectrum sharing on a dynamic, as-needed basis across three tiers of access:

• Tier 1 is incumbent users such as the federal government, fixed satellite users.
• Tier 2 is Priority Access License (PAL) users—licensed wireless users who acquire spectrum through an auction. The SAS will ensure PAL users do not cause harmful interference to Tier 1 users and will protect PAL users from interference by General Authorized Access (GAA) users.
• Tier 3 is GAA users who will deploy “lightly-licensed” devices. The SAS will ensure GAA users do not cause harmful interference into Tier 1 incumbents and Tier 2 PAL users.

If spectrum is not being used by one tier it can be accessed by another via the SAS—securely and without harmful interference.

XtremeLTE has partnered with Google to provide SAS (Spectrum Access System) to ensure our customers have secure and autonomous use of CBRS. Google's SAS is purpose-built to support dense networks across operators and to scale on-demand — from a small in-building network to the largest nationwide deployment. Register devices, monitor device status with integrated map views, and delegate administration and control access to your network across users.
