HWIC-AP-AG vs HWIC-AP-G

Answered Question
Mar 8th, 2008

Will the use of one or the other HWIC-APs allow for access speeds of 108Mbs connections with a wireless G client?

I have this problem too.

Hi Randall,

Sadly no. The number 108Mbs is the combinaton of 802.11g and 802.11a data rates, and with the subtraction due to overhead the actual throughput is much lower. Have a look;

Approximate Throughput Comparison for 802.11a, 802.11b, and 802.11g

802.11b Data Rate (Mbps)=11 Approximate Throughput (Mbps)=6

802.11g (no 802.11b clients in cell) Data Rate (Mbps)=54 Approximate Throughput (Mbps)=22

802.11a Data Rate (Mbps)=54 Approximate Throughput (Mbps)=25

From this great doc;

Hope this helps!
