same accuracy as a full-size anechoic chamber, but is sufficient for this
application. A base station simulator, such as an Agilent 8960 (shown) or Rohde
& Schwarz CMU200, is used to provide FER (Frame Error Rate) measurements.

Path loss calculation
The chamber is calibrated for path loss using a reference antenna with known
gain that is feeding a spectrum analyzer or power meter. This makes it possible to
determine the radiated power available to the receiving antenna and the path
loss:
Note: It is not necessary to know the gain of the transmitting antenna; it is included in the
path loss.
Radiated Power = Measured received power
+ Any cable losses
- Reference receive antenna gain
Path Loss = Radiated power
- Input power
