Access Points Antenna Efficiency

Posted 01 October 2012 - 11:47 AM

I need some help to calculate the efficiency of an antenna to an access point, but I'm pretty confused when it comes to the formula.
The formula I have to use is:
Er = Pr / Pi

Pr = Radiated power
Pi = Power delivered to antenna.

How do I know the radiated power and where can I find the power delivered to antenna?
Let's say I use this access point:

Could anyone help me? Couldn't find anything..

Is This A Good Question/Topic? 0
