FirstNet's spectrum has yet to be deployed significantly, and in that part of California AT&T lags for coverage. Band 14 (the spectrum FirstNet uses) devices are few and far between, let alone a cellular data gateway that supports that band. It took years for band 12 to be available on cellular data gateways, I think band 71 will likely make an appearance before band 14 gets hardware support.
