SECTION 4 Unison Remote Access Unit
The Remote Access Unit (RAU) is an active transceiver that connects to an Accel
Hub using industry-standard Cat-5/6 screened twisted pair (ScTP) cable, which deliv-
ers RF signals, configuration information, and electrical power to the RAU.
An RAU passes RF signals between an Accel Hub and an attached passive antenna
where the signals are transmitted to wireless devices.

RAU
Downlink Path: The RAU receives downlink IF signals from an Accel Hub via Cat-5/6 cable. It converts the signals to RF
and sends them to a passive RF antenna via coaxial cable.
Also, the RAU receives configuration information from the Accel Hub via the Cat-5/6 cable.
Uplink Path: The RAU receives uplink RF signals from a passive RF antenna via coaxial cable. It converts the signals to IF
and sends them to an Accel Hub via Cat-5/6 cable.
Also, the RAU sends its status information to the Accel Hub via the Cat-5/6 cable.
