The Wilson 305-1007 Zinwave Unititvity 5000 Low-Band Remote Unit is a component of Wilson Electronics' Unitivity/Zinwave distributed-antenna system (DAS), the fiber-fed infrastructure used to distribute cellular and public-safety radio coverage throughout a large building from a central hub. It's a system-level part — a hub, remote unit, power supply, or chassis — engineered to interoperate with the rest of a Unitivity/Zinwave DAS deployment rather than function on its own.
