I understand that the 11a signal distance (omni-directional) is less than that of 11b....ie...replacing 11b APs with 11a means the possibility of deploying more 11a units to have the same coverage. How about 11g? I suspect that distance is still sacrificed for speed. So, presumably, my 11g AP and 11g client card (both compliant....whenever) will automatically switch from 'g' to 'b' (54 to 11) as I move farther away from the AP? So I must deploy more 'g' APs if I want to provide 54 meg. coverage over my existing 'b' deployment?
....hope that makes sense......thx...in advance........Jamie
