The OEM must follow the regulatory guidelines and warnings listed below to inherit Laird’ modular approval.
The RM191-SM holds full modular approvals and has been certified for integration to products only by OEM
integrators under the following conditions:
1.
The antenna(s) must be installed such that a minimum separation distance of 30mm is maintained
between the radiator (antenna) and all persons at all times.
2.
The transmitter module must not be operating in conjunction with any other antenna or transmitter,
except in accordance with FCC multi-transmitter product procedures.
As long as the two conditions above are met, further transmitter testing will not be required. However, the
OEM integrator is still responsible for testing their end-product for any additional compliance requirements
required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.).
IMPORTANT NOTE: In the event that these conditions cannot be met (for certain configurations or co-location
with another transmitter), then the FCC and Industry Canada authorizations are no longer considered valid and
the FCC ID and IC Certification Number 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 and Industry Canada authorization.
The RM191-SM LoRa transmitter has been designed and approved to operate with the antennas listed below
with a maximum gain of 2 dBi. The required antenna impedance is 50 ohms.
