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 authorization is no longer considered valid and the FCC ID
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
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
