Downlink/Uplink Frame Ratio. This is the ratio of downlink to uplink MAP symbols, refer to
Appendix A and how this affects data throughput. The default option is 35:12 and the available
options are:
o 26:21
o 29:18
o 32:15
o 35:12
Maximum Distance. This is the maximum distance, defined in km, that a Base Station can
transmit to a CPE. The default is set to 11 and the User can select in the range 1 to 24.
Noise and Interference Settings. The default is 35. NI is defined as per the IEEE 802.16-e as the
noise per tone in 0.5 db steps above the -150 dBm, where 0 is -150dbm and 35 is -132.5dbm per
tone.
UCD Interval. This is WiMAX 802.16e UCD Interval value and it is to be defined in milliseconds.
Interval defined in milliseconds. The default is 1000 (1 second) and the available range is 15 up
to 10000.
DL ECINR Report Support – Specifies the mode of CINR reporting to be provided from the
CPEs. Disabling ECINR reporting should be done only in case of older CPE revisions that do not
support ECINR reporting.
5MHz Large Map Support – Available and applicable only in case of 5MHz channel bandwidth
setting.
Auto Noise Level Adjustment Support – Enables the automatic dynamic adjustment of NI and
internal settings with respect to the measured noise level on the channel. The Noise
measurement values can be seen in the radio tab.
To view the Radio Settings, at the Main Web GUI Interface Screen select the Configuration Tab, select
sector Main Menu Option, advanced Main Menu Sub-Element, 1, and then radio. The display is split into
three main grouping sections. These sections do not fit onto one screen and therefore the User has to
scroll down to view etc (refer to Figure 58 and Figure 59).
Radio Settings (configured). These are the parameters that the User can Edit.
Radio Settings (state). These are the current configurations values of the parameters.
Noise and Interference Measurements (status). These are the current configurations values of
the parameters. The Noise level is represented in 3 different measurement units.
