What kind of site survey helps you identify if roaming is working as designed?

You deployed an AP and installed its antenna, and you now need to set the AP transmit power. Given a desired EIRP of 21 dBm, and an antenna gain of 5.85 dBd connected through 25 feet of cable with a loss specification of 4 dB/100 feet.
Assuming that there is no significant loss from the connectors, what should be the transmit power level for this AP?

A bandpass filter has a maximum in-band loss of 1.5 dB, ripple of 0.4 dB, and a return loss of 15 dB. What is the minimum in-band loss?
Response:

A cable with 2.5 dB of loss is used to measure the return loss of an antenna. The measured value in-band is shown to be larger than 20 dB. What is the actual return loss of the antenna, and is it considered to be a reasonable value?
