US telecoms giant Verizon has revealed that a number of vendors and tech firms have come together at its facility in Irving, Texas to test 4G solutions using frequencies in the 3.5GHz Citizen Band Radio Spectrum (CBRS) band. Verizon’s partners have been named as Google, Ericsson, Nokia, Qualcomm Technologies, Federated Wireless and Corning, and the tests have focused on: spectrum deployment feasibility, interoperability, mobility handoffs and data rates.
The CBRS band is made up of 150MHz of shared 3.5GHz spectrum, which until now has been primarily used by the federal government for radar systems. The Federal Communications Commission (FCC) authorised shared use of the spectrum for wireless small cells in 2016. However, by using carrier aggregation (CA) and LTE-A technology, Verizon notes that it will be able to use the spectrum to boost capacity and support faster downlink transmission speeds.
In a separate statement to Fierce Wireless, a Verizon spokesperson clarified: ‘CBRS-capable devices will begin entering the line-up by the end of 2018 and will continue to expand aggressively through 2019.’
