1)i need to ask you can we do deploy 2.4 Ghz and 5 Ghz at the same physical location
mean i need to deploy 2.4Ghz b/g for data 5Ghz 802.11a for voice i read somehwre in cisco document its not recommneded i nedd calrification.
2) when i go to deploy Vowlan using 7921 and 7925 what should be the trasnmit power of AP i read 40mW
if yes then why
3) i need to know about channel overlapping recommended 15 to 20% will it be fine for voice deployment
how can i identify that channel overlapping is 15 to 20 % or 30% or 50% is there any why to identify kindly guide me
4)co-channel interfence if i incresed trasmit let say 100mW will it incresed co-channel interference and has it impact on Voice call?
then what should be the transmit power for deploying VoWlan +data to reduce co-channel interference
