The Micro Base Station also contains the wireless IEEE 802.16a MAC and
modem. It includes two 3.5/1.75 MHz PHY channels that provide provisioning to
the planned support for a future release of 2
link redundancy. In the current release, a single channel is supported.

AU-ODU
The AU-ODU of the Micro Base Station, identical to the AU-ODU of the modular
Base Station, is a high power, full duplex multi-carrier radio unit that connects to
an external antenna. It is designed t
robustness utilizing high transmit power and low noise figure. It supports a
bandwidth of up to 14 MHz, enabling future options such as increased capacity
through the use of a multiplexer or larger channels (e.g. 7/14 MHz).
The Micro Base Station unit connects to the AU-ODU via an Intermediate
Frequency (IF) cable. The IF cable carries full duplex data, control and
management signals between the Micro Base Station and the AU-ODU, as well as
power (48 VDC) and 64 MHz synchronization reference clock from the Micro Base
Station IDU to the AU-ODU. The IF Tx and Rx frequencies are 240 MHz and
140 MHz, respectively. IDU-ODU service channel at 14 MHz serves for bi-
directional control, status and management signaling.
