SECTION 5 LGCell Remote Access Unit
The Remote Access Unit (RAU) is an active transceiver that connects to an Expan-
sion Hub using industry-standard Cat-5 UTP/STP cable. The cable also delivers elec-
trical power to the RAU.
An RAU passes electrical signals between an Expansion Hub and an attached passive
antenna.
