Antenna Installation Guidelines
Install the antenna in a place covered by the LTE signal.
Antenna must not be installed inside metal cases
Antenna shall also be installed according Antenna manufacturer instructions
Antenna integration should optimize the Radiation Efficiency. Efficiency values > 50% are
recommended on all frequency bands
Antenna integration should not dramatically perturb the radiation pattern. It is preferable to get, after
antenna installation, an omnidirectional radiation pattern, at least in one pattern cut
Antenna Gain must not exceed values indicated in regulatory requirements, where applicable, in
order to meet related EIRP limitations. Typical antenna Gain in most M2M applications does not
exceed 2dBi
If the device antenna is located farther than 20cm from the human body and there are no co-located
transmitters, then the module FCC/IC approvals can be re-used by the end product
If the device antenna is located closer than 20cm from the human body or there are co-located
transmitters, then additional FCC/IC testing may be required for the end product (the module FCC/IC
approvals cannot be reused)
