is the radio only half duplex?

[yeled1257]

we have a 1240 access point on our speed test we are getting only about 13MB when we should get around 30MB my vendor is telling me thats becuase the radio only works on half duplex is that correct??

Yes... compare it to a hub environment it is a shared media.... all devices have to listen and wait for their turn to talk.

thx for the reply

is there any cisco doc that show that? i need to show it to my boss!

so would it make sense that the speed shows half of what it suppose to be?

Here is one that I found... just try doing a search on Google if your boss needs more info:
