Hi, qualnet support team, some question need your help.

In the config file, there are three parts incuding the varible PHY802.11-DATA-RATE , for example:


#************* Radio/Physical Layer ***********

PHY-MODEL PHY802.11b
PHY802.11-AUTO-RATE-FALLBACK NO
# bandwidth in bps. supported data rates: 1Mbps, 2Mbps, 5.5Mbps, 11Mbps
PHY802.11-DATA-RATE 2000000

.......


#----------------Subnet ID 11 -----------------
SUBNET N8-192.0.0.0 { 1 thru 10 } 817.16 873.13 0.0
[ N8-192.0.0.0 ] PHY-MODEL PHY802.11a
[ N8-192.0.0.0 ] PHY802.11-AUTO-RATE-FALLBACK NO
# bandwidth in bps. supported data rates: 6Mbps, 9Mbps, 12Mbps, 18Mbps, 24Mbps, 36Mbps, 48Mbps, 54Mbps
[ N8-192.0.0.0 ] PHY802.11-DATA-RATE 6000000

.......

.........
[ 1 thru 10 ] PHY-MODEL PHY802.11a
[ 1 thru 10 ] PHY802.11-AUTO-RATE-FALLBACK NO
[ 1 thru 10 ] PHY802.11-DATA-RATE 24000000
...........

Can you explain me the meaning and the difference for the varible PHY802.11-DATA-RATE in these three parts?
If I want to set the data translate rate from termain station to AP as 6, which part should I set the value?

Thanks with regards.
