GM47/48 Design Guidelines
BA/SEM/MSC 02:0006 Rev PA1 23
6.3 SIM Testing
SIM testing does not need to be carried out since it is a passive
component. Points to note regarding the implementation of the SIM
card holder are as follows.
• SIM presence must be implemented to comply with the module
approval conditions.
• Any manufacturers SIM card holder can be used and this can also
be either 6 or 8 pins.
6.4 EMC/ESD & Safety
EMC and safety tests according to the ITU/GSM and FCC standards
will have to be completed as part of the mandatory testing. The GM
47/48 were originally type approved outside of a metal box. Additional
shielding is not strictly required the external application. This is the
responsibility of the system integrator. Overall ESD protection should
be guaranteed by the system integrator.
The EMC standard which the application must be tested to is EN 301
489-7, this can be found at the following web site.

The safety standard which the application must be tested to is EN
60950, the can be found at the following web site

6.5 RF Testing
6.5.1 GM47
As long as the antenna connected to the module is of the correct
impedance as specified in section 3.7 and is passive further RF testing
for TA is not required. Although it should be noted that radiation
performance is the responsibility of the system integrator.
6.5.2 GM48
According to the US rules (GM48) any change in RF path i.e. the
antenna path will require new approval according to FCC part 22 and
24.
