The Sector WIMAX Settings parameters that the User can configure are defined below:
Maximum Uplink Rate. This parameter provides the means to globally fix the maximum
modulation rate in the Uplink direction (defined as Subscriber to Base Station). If the User wants
to dynamically adapt the rate to the maximum then the default value of QAM64_5/6 can be left
unchanged. Refer to Appendix A for an explanation of how the maximum modulation rate,
defined as MCS Rate, effectively caps the system data throughput. If the User wants to
physically cap the rate and hence cap the throughput, they are free to select from the following
MCS rates:
o QAM64_5/6
o QAM64_3/4
o QAM64_2/3
o QAM64_1/2
o QAM16_3/4
o QAM16_1/2
o QPSK_3/4
o QPSK_1/2
Maximum Downlink Rate. This parameter provides the means to globally fix the maximum
modulation rate in the Downlink direction (defined as Base Station to Subscriber). The default is
QAM64_5/6 and the same options as maximum uplink rate parameter are available.
Antenna TX Mode. This the option to define the Smart Antenna Capabilities that were described
in section 2.3.2.3. The default setting is MIMO-A and the available options are:
o MIMO-AB
o MIMO-A
Auto Power Control. The transmit power of a Subscriber is controlled via automatic algorithms
in the Base Station. This control of the transmit power ensures optimum performance. The
default is open-loop and the available options are:
o open-loop. In the case of an open loop algorithm, the Base Station sends a signal to the
Subscriber of the required settings and the Subscriber controls its transmit power
dynamically.
o closed-loop. In the case of closed loop, the Base Station controls the Subscriber transmit
power settings with a full measurements loop.
Auto Transmit After Reset Mode. When this is enabled the Base Station will automatically start
transmitting upon a power cycle. If this is disabled, then the User will have to manually start the
transmission.
Channel Bandwidth. This is the current channel bandwidth of the radio transmission. The
default is 10MHz and the options are:
o 10MHz
o 7 MHz
o 5MHz
DCD Interval. This is the WiMAX 802.16e DCD Interval value and it is to be defined in
milliseconds. The default is 1000 (1 second) and the available range is 15 up to 10000.
Default Provisioning Enabled. The User has the choice to enable or disable this feature. If this is
enabled, then the Quality of Service (QoS) profile for the CPE will be the Default QoS that has
been provisioned. This is defined as QoS profile “1”. If this is disabled then the QoS profile will
be that as defined for the particular CPE.
