A hospital environment was designed to guarantee RF coverage at or better than -67 dBm in the 5 GHz spectrum. The customer mandates that RRM be used for DCA and TPC in both bands. After deployment, why do many of the legacy 802.11b/g devices have difficulty maintaining connectivity?
A. Excessive co-channel interference in the 2.4 GHz band exists.
B. Excessive overlapping channels in the 2.4 GHz band exists.
C. TPC drastically reduces Tx power in the 2.4 GHz band.
D. TCP drastically increases Tx power in the 2.4 GHz band.
I think is C
As anonymous says, if the WLAN was designed to have -67 dBm on 5 GHz there will be a lot of APs near of each other.
But the TPC is active in 2,4 Ghz band. So TPC will reduce TX to avoid overlapping.
Sorry, I think you’re all wrong!
A is correct as I see it
Ok, so TPC will reduce the power to avoid overlapping. BUT why is that now a problem for 802.11b/g devices now if RRM is reducing the power!?!? This is a good thing not bad.
I think it’s A because when they placed the APs for 5 GHz (which has many channels) they didn’t consider the 2.4 Ghz which only has 3 usable channels and now they are overlapping on THE SAME channels which is the “co-channel interference” issue.
Please challenge me if you think I’m wrong
Trust me, Jackman, and 0mega, it’s definitely C.
Hell yes this is C. No better answer than C.
I think is B, if was designed to have -67 db on 5 GHz there is going to be a lot of APs near of each other, and so the overlapping on channels 1,6 and 11 channels is going to be high
C

Are you sure? What’s the reasoning?
Correct = B
This is dead wrong.
5 GHz better then -67 will require many AP.
The TPC will reduce the TX power on 2.4 GHz
