Important Compliance Information for
North American Users
The AirPrime WP8548 module has been granted modular approval for mobile
applications. Integrators may use the AirPrime WP8548 module in their end
products without additional FCC
/ IC (Industry Canada) certification if they meet
the following conditions. Otherwise, additional FCC
/ IC approvals must be
obtained.
1. The end product must use the RF trace design approved with the AirPrime
WP8548 module. The Gerber file of the trace design can be obtained from
Sierra Wireless upon request.
2. At least 20 cm separation distance between the antenna and the user’s body
must be maintained at all times.
3. To comply with FCC / IC regulations limiting both maximum RF output power
and human exposure to RF radiation, the maximum antenna gain including
cable loss in a mobile-only exposure condition must not exceed:
Note: Gain values are
preliminary and subject to
change.
· 4.0 dBi in Cellular band
· 3.0 dBi in PCS band
4. The AirPrime WP8548 module may transmit simultaneously with other collo-
cated radio transmitters within a host device, provided the following conditions
are met:
· Each collocated radio transmitter has been certified by FCC / IC for mobile
application.
· At least 20 cm separation distance between the antennas of the collocated
transmitters and the user’s body must be maintained at all times.
· The output power and antenna gain in a collocated configuration must not
exceed the limits and configurations stipulated in the following table.
