each end of the wireless link. Users are required to simply specify one unit type as master unit (MU) and one unit
as remote unit (RU). The hardware consists of a high gain dual polarized panel antenna with the radio portion
integrated into a cast aluminum case on the back of the antenna, or an external dish antenna. The unit utilizes
Power-over-Ethernet (PoE) and is designed for outdoor environments. The cable entry point can accommodate both
Shielded twisted pair Cat5 (STP), Unshielded twisted pair Cat5 (UTP), with the addition of conduit for tower
