I set my wifi access point data rate to 802.11G
54Mbps.
Then ping the wifi station from the access point.
Attached is all the ICMP data captured by ethereal.
I want to calculate the data rate between the wifi
station and the access point.
How to do that?
My calculation is:
Data rate = number of bytes transmitted / time

Frame 2:
    (74 bytes on wire, 74 bytes captured)
    Arrival Time: Aug 18, 2005 16:09:28.558839000
    Time delta from previous packet: 0.000086000
seconds

Data rate
= 74 * 8 bit / 0.000086000 seconds
= 6883721 bit/s


Frame 3:
    (588 bytes on wire, 588 bytes captured)
    Arrival Time: Aug 18, 2005 16:09:28.599556000
    Time delta from previous packet: 0.040717000
seconds
    Time since reference or first frame: 0.040803000
seconds

Data rate
= 588 * 8 bit / 0.040717000 seconds
= 115529 bit/s

Frame 4:
    (586 bytes on wire, 586 bytes captured)
    Arrival Time: Aug 18, 2005 16:09:28.599565000
    Time delta from previous packet: 0.000009000
seconds
    Time since reference or first frame: 0.040812000
seconds

Data rate
= 586 * 8 bit / 0.000009000 seconds
= 520888889 bit/s

Frame 5 (1100 bytes on wire, 1100 bytes captured)
    Arrival Time: Aug 18, 2005 16:09:28.639421000
    Time delta from previous packet: 0.039856000
seconds
    Time since reference or first frame: 0.080668000
seconds

Data rate
= 1100 * 8 bit / 0.039856000 seconds
= 220795 bit/s

Frame 6:
    (1098 bytes on wire, 1098 bytes captured)
    Arrival Time: Aug 18, 2005 16:09:28.639430000
    Time delta from previous packet: 0.000009000
seconds
    Time since reference or first frame: 0.080677000
seconds

Data rate
= 1098 * 8 bit / 0.000009000 seconds
= 976000000 bit/s


Average data rate
= (frame 1 + frame2 + ... + frame6) / (time delta
between frame 1 and frame6)
= (76 + 74 + 588 + 586 + 1100 + 1098) * 8 bit /
0.080677000 seconds
= 349244 bit/s

Is my calculation correct?
Any data rate greater than 54Mbps should be discarded,
shouldn't it?
