Not sure if this is a repost, havent seen my old post go up yet..
I am due to do a site survey in the coming months, and just wondering is there any difference in doing the survey with a different AP that what is to be installed.When i say different, its not going to be a too different AP!
The customer is going with 1242's once the survey is complete, but I only have 1231's and 1130's to use for the survey.
I have looked at data sheets and havent seen too much difference between the 3 models, when using the standard aerials, which they will be using in the end.
Would this be acceptable?
Thanks in advance
For a simple field measurement, it all boils down to three things; the antenna, the transmitter output, and the receiver's sensitivity and selectivity.
Of the three, the most likely to be variant is the receiver ... mostly because radio components may vary and be better (yay technology!) or worse (f'n beancounters making things being built cheaper).
Improved sensitivity without improving selectivity would be a Bad Thing (like having a wide-open amplifier ... noise gets amplified too). Selectivity is the ability of a receiver to discriminate the desired signal from the spectrum that also includes other transmitters and noise-type interferers.
As long as those three basic characteristics are substantially similar, the site survey findings will be substantially similar.
Even if the characteristics are not the same, if you know what they are, you can calculate the compensation, adjust the hardware, or add additional "fudge factor."
IMO, given the state of today's hardware, if the antenna(s) are the same (type and substantially similar Smith charts -- the radiation patterns), you'll get a valid survey.
