The following basic MAC parameters may be set or viewed:
Frame Duration: The maximum frame length. Set the frame length to 5, 10, or 20 ms.
Downlink Percentage: This parameter sets the downlink/uplink boundary of the TDD frame by setting the percentage
of bandwidth allocated to the downlink. Set the downlink percentage to a value between 10%-90% depending on the
frame duration (see the following table). The remainder will be allocated to the uplink.
Frame Synchronization Mode: Set this parameter to Independent.
BSID: A 48-bit value, defaulting to 1. Set this to a unique value for each BS, where the upper 24 bits equal the
Operator ID. Contact the IEEE Registration Authority to for an Operator ID. If one can not be obtained, use a 24-bit
random number until one can be obtained.
Frame Duration Minimum Downlink Percentage Maximum Downlink Percentage
5 ms 40% 50%
10 ms 40% 70%
20 ms 40% 70%
