Specifications

Antenna
(1) The antenna must be installed such that 20 cm is maintained between the antenna and users,
(2) The transmitter module may not be co-located with any other transmitter or antenna.
In the event that these conditions cannot be met (for example certain laptop configurations or co-location
with another transmitter), then the FCC/IC authorization is no longer considered valid, and the FCC ID/IC
cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for
re-evaluating the end product (including the transmitter) and obtaining a separate FCC/IC authorization.
To comply with FCC regulations limiting both maximum RF output power and human exposure to RF
radiation, maximum antenna gain (including cable loss) must not exceed.

Remark:
1. The EUT supports Cyclic Delay Diversity (CDD) mode, and CDD signals are correlated.
2. For CDD transmissions, directional gain is calculated as follows, N
ANT
= 4, N
SS
= 1.
If all antennas have the same gain, G
ANT
, Directional gain = G
ANT
+ Array Gain, where Array Gain is as follows.
 For power spectral density (PSD) measurements on all devices,
Array Gain = 10 log (N
ANT
/ N

) dB = 6.02;
 For power measurements on IEEE 802.11 devices,
Array Gain = 0 dB for N

Manual Information to the End User
The OEM integrator has to be aware not to provide information to the end user regarding how to install
or remove this RF module in the user’s manual of the end product which integrates this module. The end
user manual shall include all required regulatory information/warning as show in this manual.
