Anritsu is demonstrating its ability to test emerging Citizen Broadband Radio Service (CBRS) chipsets and modules at Mobile World Congress Americas 2018. The Anritsu Radio Communications Analyzer MT8821C is conducting throughput tests on a Sierra Wireless AirPrime EM75 Series LTE-Advanced Pro cellular module that supports CBRS band applications.
The MT8821C can conduct RF parametric and throughput tests in the 3.5 GHz CBRS band to verify that the Sierra Wireless networking module meets CBRS specifications. Although the MT8821C supports 8-way Carrier Aggregation (8 CA) and 4x4 Multiple-Input Multiple-Output (4x4 MIMO), the demonstration will showcase the capability of the module, which is 3 CA and 2x2 MIMO for CBRS applications.
Testing CBRS devices and systems is becoming increasingly important as mobile operators prepare to utilize Band 48 to increase capacity and speeds of LTE networks. CBRS is a revolutionary license sharing service utilizing 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-MHz channels that are expected to be used by mobile operators. General Authorized Access (GAA) makes any portion of the 3550-3700 MHz band not assigned to a higher tier available to other users. Click here to learn more about this test system.
