my external antenna is "AIR-ANT24120" 12dbi.Bcoz of some TRA issues i'm forced to use 5.725-5850.From TRA i got the instruction that, if you put 12 dbi or 13.5 dbi antenna the maximum power is should not exceed " 2W max.mean EIRP".
20 dbm/Mhz max. mean EIRP density.
so in this case how can i proceed with
1300 AP/BR. will this unit support 5.7 band.i need to change this unit? please give your suggestions.
To complete the calculation, it's necessary to know how much of what kind of cable is connecting the AP to the antenna (to calculate loss of the "intentional radiator").
For example, if you have 50 feet of coax that's rated at 6db loss per hundred feet, you are introducing about 3db f loss (then add another ~.25 db loss for each connector - AP-Cable-arrestor-cable-antenna).
In the above example, if the AP was putting out 20mw (13dbm):
There's also a dbm/mw conversion table in the WebGUI of the AP (in the "Interfaces" screen where you'd adjust your power).
Short version:once you have the total gain of the system (connectors(-), coax(-), arrestor(-), antenna (+)), adjust your output power to stay below your local max Effective Isotropic Radiated Power (EIRP).
