4.8.5.3.1 MAC Parameters
The MAC menu enables viewing/updating the following parameters:
4.8.5.3.1.1 ID Parameters
The Operator ID, Cell ID and Sector ID constitute together the Base Station ID,
which is the unique identifier of the AU. An SU can be authenticated by the AU
only if its defined parameters match the Base Station ID configured for the AU.
The Operator ID and Cell ID are defined for the Base Station (see Section 4.4.2.4)
and are used by all AUs in the Base Station. In the AU's MAC Parameters menu
they are available only in the Show option.
The Sector ID parameter consists of three digits in the range of 0 to 255.
The default Sector ID is 206.
Changes in Sector ID are applied only after reset.
4.8.5.3.1.2 ARQ Enable/Disable
The ARQ Enable/Disable parameter controls whether to use an ARQ algorithm for
detecting errors and requesting retransmissions of applicable unicast messages
(applicable only for Best Effort and Non Real Time services).
The default is Disable.
4.8.5.3.1.3 Maximum Cell Radius
The Maximum Cell Radius is used to adapt various timing parameters of the MAC
to the time it takes a message to reach its destination. This time delay is
dependent upon the distance between the originating and receiving units. The
timing parameters should be adapted to the largest expected delay, which is
determined from the distance from the AU of the farthest SU served by it.
