5.1 RAU Overview
The Remote Access Unit (RAU) is an active transceiver that connects to an Expan-
sion Hub using industry-standard CATV cable, which delivers RF signals, configura-
tion information, and electrical power to the RAU.
An RAU passes converted 1F to RF (Downlink) and converted RF to 1F (Uplink) sig-
nals between an Expansion Hub and an attached passive antenna where the signals
are transmitted to wireless devices as shown in Figure 5-1.
