L600 and L850!
We are beginning the process of turning over to one antenna for dual low band.
You can spit on low band all day until you need it. Imagine when n5/n71 kicks in 20+MHz of tree proof speedtests, land mobile LE comms and plenty of data/IoT subscribers who just want a complete LTE network and not a switcher/urban parallel.
T-Mobile literally wins the farm here if this expands, innovates. Our BRS is in the garage so there is that too.
