Strange Aironet 1200 AP Behavior

Hi,

I have 5 aironet 1200 APs connected to a 3550 switch. We have a 10Mb metro ethernet connection coming in to the location, but when I speed test the network the APs will only top out at about 5mbs, and I am the only person associated to the AP. When connected to the switch I get the full 10 MB. I have also noticed a bunch of transmit errors on the radio interface . Anyone have any ideas?

Thanks!

Thank you for replying Brad,

I have another quick question. Is there an practical BW limit for the Aironet APs? In a perfect environment would I be able to download at a rate of 10Mbs if there was no possibility of interference?

Thanks,

Boris

Hi Boris,

Throughput of the 802.11g Access Point with 802.11b and 802.11g client adapter cards in a mixed environment:

  1. The throughput for 802.11g AP having only 802.11g clients ( without
802.11b clients ) connected is about 22 Mbps. This value assumes optimal radio configuration.

  1. The throughput for 802.11g clients to 802.11g AP radios drops to about 8 Mbps when 802.11b clients also use the 802.11g Access Point ( AP ) with Request to Send/Clear to Send ( RTC/CTS ).

  2. The throughput for 802.11g clients to 802.11g AP radios drops to about 14 Mbps when 802.11b clients also use the 802.11g AP with Request to Send to Self ( RTC to Self ).
