All the above antenna designations were tested, and the sample 1 was found to be the worst cases during the pr-scanning
test. This sample of the worst case was used for final testing and collecting test data included in this report.

NOTE
1. ((dBm/Chain 1)/10^Log) +( (dBm/Chain 2)/10^log)+((dBm/Chain N)/10^log)=Combined peak output
power in mW.
For example: 2x3 MIMO: Chain 1 TX peak output power is 16 dBm; Chain 2 TX peak output
power is 17 dBm. The combined peak output power is (16/10)^log= 39.81mW +
(17/10)^log=50 mW. Combined peak out power is 39.81+50.12=89.93 mW( 19.53 dBm)
2. Directional gain = gain of antenna element + 10 log(# of TX antenna elements).
For example: if EUT is a 2x3 MIMO with each antenna gain=3dBii, then the directional gain is
= 3 +10log(2)=3+3=6 dBi ( no power reduction).
If (EUT is a 3x3 MIMO with each antenna gain =3dBi, then the directional gain is =
3+10log(3)=3+4.77=7.77dBi ( output power needs to reduce by 1.77dBi, so the highest conducted output
power allowed is 28.23dBm.
