Connectivity providers traditionally rely on licensed (captive) spectrum to underpin their operations. That is changing as the ability to aggregate (bond) unlicensed spectrum with licensed spectrum becomes feasible.
The use cases involve use of unlicensed or lightly-licensed CBRS spectrum, LAA, LTE-U, MultiFire and other forms of spectrum aggregation (mobile with unlicensed).
AT&T, Verizon and T-Mobile US already indicate they will use CBRS, and all have deployed LAA in their networks.
