What I've observed is[1]  ( No activity on wlan0 )  Bit Rate is 1MB/s
[1]-----------------
  iwconfig wlan0
wlan0     IEEE 802.11abgn  ESSID:"cisco"
           Mode:Managed  Frequency:2.447 GHz  Access Point: 
00:25:9C:89:DX:FC
           Bit Rate=1 Mb/s   Tx-Power=15 dBm
           Retry  long limit:7   RTS thr:off   Fragment thr:off
           Power Management:off
           Link Quality=68/70  Signal level=-42 dBm
           Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
           Tx excessive retries:108  Invalid misc:4   Missed beacon:0

Sending some data through wlan0 ( may be ping yahoo.com ) Bit Rate is 
150MB/s

[2]-------------

iwconfig wlan0
wlan0     IEEE 802.11abgn  ESSID:"cisco"
           Mode:Managed  Frequency:2.447 GHz  Access Point: 
00:25:9C:89:DX:FC
           Bit Rate=150 Mb/s   Tx-Power=15 dBm
           Retry  long limit:7   RTS thr:off   Fragment thr:off
           Power Management:off
           Link Quality=69/70  Signal level=-41 dBm
           Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
           Tx excessive retries:102  Invalid misc:4   Missed beacon:0


May be this can clear the matter :-)
