Can I bind -a and -g radio links together?

Answered Question
Mar 9th, 2007

Hi,

I have two Cisco 1242 APs with both -a and -g radio. Can I set up them as point to point bridges and bind the 54M -a and 54M -g links together to get a 108M link? How is the traffic pass through in these two links? load balance?

Thanks,

Justin

Hi Justin,

You can only connect to one radio at a time,so this idea (a good thought!) will not work.Also, don't forget that the 54M numbers are really only theoretical and not a reflection of the ture throughput. 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 good doc;

Hope this helps! I know its a bummer :(
