Anritsu, Sierra Wireless Complete CBRS Demonstration
Thursday, September 13, 2018 | Comments

Anritsu will demonstrate its ability to test emerging Citizen Broadband Radio Service (CBRS) chipsets and modules. The Anritsu analyzer will conduct throughput tests on a Sierra Wireless Long Term Evolution (LTE)-Advanced Pro cellular module that supports CBRS band applications.

The MT8821C will conduct RF parametric and throughput tests in the 3.5 GHz CBRS band to verify that the Sierra Wireless networking module meets CBRS specifications. The demonstration will showcase the capability of the module, which is three-way carrier aggregation (CA) and 2x2 multiple input multiple output (MIMO) for CBRS applications.

Testing CBRS devices and systems is becoming increasingly important as mobile operators prepare to use band 48 to increase capacity and speeds of LTE networks. CBRS is a license sharing service using a three-tiered spectrum authorization framework. The shared spectrum is considered a solution to help service providers meet network challenges associated with increased data demands and coverage.

Incumbent access, priority access and general authorized access are the three CBRS tiers. Incumbent access is for authorized federal and grandfathered fixed satellite service users, while priority access consists of priority access licenses (PALs) for 10-megahertz channels that are expected to be used by mobile operators. General authorized access (GAA) makes any portion of the 3.5 GHz band not assigned to a higher tier available to other users.
