Antenna Requirements
Every module has to be equipped with a proper antenna with specific characteristics.
The antenna for RC3000A must meet the following requirements:
This device is to be used only for mobile and fixed application. End-users must be
provided with transmitter operation conditions for satisfying RF exposure compliance.
OEM integrators must ensure that the end user has no manual instructions to remove or
install RC3000A modem. Antennas used for this OEM module must not exceed 3dBi
gain for mobile and fixed operating configurations.
GSM Antenna – Installation Guidelines
•
Install the antenna in a place covered by the GSM signal
.
The Antenna must be
installed to provide a separation distance of at least 20 cm from all persons and
must not be co-located or operated in conjunction with any other antenna or
transmitter. In case of this requirement cannot be satisfied, the system integrator
has to assess the final product against the SAR regulation.
•
Due to the RC3000A antenna characteristics to environmental sensitivity, the
antennas location should consider that the performance could be affected by a
building’s characteristics or other obstructions that may interfere with the
modules ability to make a strong connection to the intended cellular signal
provider.
ANTENNA REQUIREMENTS
