Guidelines for antenna RF interface design
The RF radiating power profile of the SARA-N211 and SARA-N310 modules is compliant to all the
applicable 3GPP / ETSI standards, with a maximum of 250 mW RF average power according to the
LTE Cat NB1 / NB2 Power Class stated in
The RF threshold power of the application device integrating a SARA-N211 or SARA-N310 module is
defined, according to the IEC 60079-0 ATEX standard
, as the product of the effective output
power of the module multiplied by the antenna gain (implemented/used on the application device).
The RF threshold power of the application device integrating a SARA-N211 or SARA-N310 module
must not exceed the limits shown in
, according to the IEC 60079-0 ATEX standard

☞
The system antenna(s) implemented/used on the application device integrating a SARA-N211
and/or SARA-N310 module must be designed/selected so that the antenna gain (i.e. the combined
transmission line, connector, cable losses and radiating element gain) multiplied by the output
power of the module does not exceed the limits shown in
