Radio PC Card Configuration 31
E-EQ-MX2RG-L-ARC MX2 Reference Guide
Microwave_Robustness
This option should only be used when troubleshooting slow performance of the network that
could be related to in-band interference from microwave ovens.
Use this option when experiencing recurrent “bursts” of in-band interference exhibited by specific
units where the unit (or the access point) is close to a microwave oven or a microwave oven is
located in the signal path between the unit and the access point. The radio will try to retransmit the
“lost messages”. When retransmission fails again, the radio in Auto Transmit Rate Select
Mechanism mode will attempt to retransmit the message again at a lower data speed. (See
Transmit_Rate)
Selecting “Y” will enable fragmentation of data frames when the automatic transmit rate selection
switches to a lower transmit rate. Fragmentation will avoid increased vulnerability due to longer
frame lengths of transmissions at lower data speeds.
Valid: Y=Yes, N=No
Default: N
Transmit_Rate
Controls the data rate the WaveLAN card will use. Supported rates depend on the card. If the card
does not support the selected rate, the default value of 3 is selected automatically.
Valid: 1=Fixed Low
2=Fixed Standard
3=Auto Rate Select (High)
4=Fixed Medium
5=Fixed High
6=Auto Rate Select (Standard)
7=Auto Rate Select (Medium)
Default: 3
Medium_Reservation
Enables RTS/CTS communications. Sets the frame length threshold that determines when the
station should start using RTS/CTS.
Valid: 0-2347
Default: 2347
Note: The use of Medium Reservation is recommended in network environments where the
density of the WaveLAN stations and WavePOINT-II access points is very low, and
where there is poor network performance due to excessive frame collisions at the
WavePOINT-II access points.
Card_Power_Management
Configures the power management used by the station in an ESS. The recommended mode is
Enhanced Power Management (EPM) for hand held computers. In this mode, the station switches
between Power Save Mode (PSM) and Continuous Active Mode (CAM), based on activity. Any
frame transfer switches the station to CAM. Inactivity for 100ms switches the station to PSM.
For hand held computers, the default is EPM.
Valid: 0=CAM (No power savings)
1=EPM
2=PSM (Maximum power savings)
Default: 1
