TD-LTE is the 4G standard developed for use across China, and it is now being adopted by operators across the globe. lightRadio Metro Radio houses two lightRadio cubes, fully integrated with a directional antennae, allowing it to provide the coverage normally associated with a much bulkier, heavier remote radio unit linked to an external antenna via an RF coaxial cable.
