Verizon and partners drive advancements on CBRS spectrum

Verizon is collaborating with Corning, Ericsson, Federated Wireless, Google, Nokia and Qualcomm on end-to-end system testing of solutions for CBRS (Citizen Band Radio Spectrum) spectrum.

Testing is being done at Verizon’s facility in Irving, Texas. The end-to-end system tests are designed to accomplish several goals on the path to widespread commercial deployment:

To test and verify the Spectrum Access System algorithms from Google and Federated Wireless are consistently providing the best channel match from the SAS database.
To test data rates, modulations and the customer experience using CBRS spectrum.
To test interoperability between infrastructure providers to ensure seamless handoffs between CBRS spectrum and licensed spectrum for customers.
To test mobility handoffs on the CBRS spectrum.
To evaluate performance and data from LTE over CBRS spectrum.

Federated Wireless and Google are providing prioritization through the Spectrum Access System (SAS) that dynamically prioritizes traffic within the FCC’s spectrum sharing framework for this band.

Qualcomm is providing its Snapdragon LTE modem, which is needed to access LTE on CBRS on mobile devices.

Corning, Ericsson and Nokia have provided indoor and outdoor radio solutions which can run on the CBRS Spectrum.

Corning provided a SpiderCloud Enterprise RAN composed of a Services Node and SCRN-330 Radio Nodes.

Ericsson’s Radio System solution is comprised of 4x4 MIMO, 4x20MHz Carrier Aggregation, including CBRS spectrum delivered over infrastructure aggregating Ericsson’s outdoor micro base station (Radio 2208 units) with the indoor B48 Radio Dot System in the same baseband (5216 units).

Nokia provided FlexiZone Multiband Indoor (MBI) BTS, FlexiZone Multiband Outdoor (MBO) BTS and FlexiZone Controller (FZC).
