The Alliance for Telecommunications Industry Solutions and the CBRS Alliance said they will work together to resolve technical issues involving the citizens broadband radio service (CBRS) spectrum band. Among other things the ATIS, CBRS Alliance agreement aims to address challenges that arise when the spectrum is used on both a licensed and unlicensed basis to support mobile service.

The CBRS band includes spectrum between 3550-3700 MHz, a portion of which will be auctioned and a portion of which will be available for unlicensed use on a shared basis with incumbent military users. A spectrum access system will prevent unlicensed users from using the spectrum in areas where it is already in use.

Among other things, the CBRS Alliance is the group that created the OnGo brand for shared spectrum technology. Initially, the brand will apply to the CBRS band but longer term could be used for other spectrum bands used by communications service providers on a shared basis.

ATIS, CBRS Alliance Plans
Specific technology issues that ATIS and the CBRS Alliance will address include international mobile subscriber identity (IMSI), home network identity (HNI), priority services and radio access networks, along with legal and regulatory compliance topics.

The ATIS, CBRS Alliance work is the latest example of how various industry groups have cooperated and collaborated to address a range of technical issues related to the CBRS band. Previously, the CBRS Alliance worked with the Wireless Innovation Forum to divvy up responsibility for establishing various types of testing aimed at ensuring proper functionality of various types of equipment supporting service in the CBRS band.

In a press release, ATIS President and CEO Susan Miller also noted that ATIS and the CBRS Alliance previously collaborated to create “infrastructure to utilize the 3.5 GHz CBRS band for LTE services, while also advancing IoT applications.”
