Drop test
First case: 0.3 m in height. Drop the
ME909 module on the marble terrace
with one surface facing downwards
twice. Six surfaces should be tested.

5.8 EMC and ESD Features
EMC tests have to be performed on the application as soon as possible to detect any
potential problems.
Special attention should be paid to the following:
Possible harmful emissions radiated by the application to the RF receiver in the
receiver band.
ESD protection is mandatory on all signals which are externally accessible
Typically, ESD protection is mandatory for the following:
− UIM
− USB
Length of the USIM interface lines (preferably <10 cm).
EMC protection on audio input/output (filters against 900 MHz emissions).
Ground plane: recommends a common ground plane for analog/digital/RF
grounds.
