Unlicensed Band 48 Opens for Business
The FCC this week granted permission for initial commercial service to commence in the unlicensed part of band 48, also known as CBRS, a radio frequency band spanning the range of 3550 - 3700 MHz. In a new and unique arrangement, consumer phones will be able to cellular technologies like LTE in an unlicensed band that also has incumbent users such as the military and satellite operators. To prevent interference, five companies will operate central databases that coordinate access to the band in real-time. Having proven their systems in certified lab tests, it is these five Spectrum Access System (SAS) Administrators that have received permission from the FCC to begin "initial commercial deployment", which is both a real-world test phase and a commercial launch. The five approved Administrators are Google, Sony, Federated Wireless, Amdocs, and CommScope. Verizon has been most vocal among the major US carriers about deploying service in band 48 for its customers. The most recent flagship phones from Samsung, Apple, LG, OnePlus, and Razer already support band 48. In mid-2020, the FCC plans to auction a different part of the CBRS band that will be licensed in a more traditional way for deployment of 5G service.
