Hi, distance is subjective... What will it be communicating with, at which frequency, what is the minimum accepted data rate and is there clear line of site (including the fresnel zone)?
If you are in the middle of a wide open field, you have no physical obstacles around, no wireless from neighbors, no bluetooth, and all data rates are open.
In a single direction, you would get around 30 metres.
I think as Rik and Leo mention, it's a subjective measure. There are too many variables, like the ones they mention, as well as the wide range of clients and their various receive thresholds for data rates. Cisco likely discontinued any mention of client access range because of this. Just checking the data sheets for the 1600/2600/3600 and they don't list ranges,just receive sensitivity thresholds per data rate/MCS. To find the range in your environment the only real way is to do a full, proper active survey.
