The Roaming Connectivity Lab (RCL) scope of work is to address connectivity challenges with networks that fall outside the roaming connectivity ecosystem established in the industry: private networks and neutral hosts.

Neutral host networking is a cost-effective architecture that uses private LTE or 5G to extend public carrier cellular signals into locations or areas with poor signal strength. Licensed spectrum can also be used. The technology uses the internal switching architecture of a building, along with private LTE or private 5G. Businesses can connect to carrier networks over encrypted tunnels via the internet. New use cases for deploying neutral host networks are emerging.
