Filter the SIM VCC signal with
a 10 uf / 10 V capacitor to help
with the line length.
Primary and secondary serial
Interfaces
The Novatel Wireless M2M Enabler IIIG module uses a 1.8V
digital interface. The RS-232 signals must be level-shifted to
get standard levels. These signals must be ESD-protected.
Reset Interface
Resets the Novatel Wireless M2M Enabler IIIG module when
tied low.
Audio/Microphone
Interface
Preliminary balancing on Novatel Wireless M2M Enabler IIIG
module.
Maximum length TBD
Testing the following parameters verifies the RF parameters that may be affected by such
things as RF path loss, power supply noise, and external interference.
Functionality Parameters to be Tested
Transmitter Frequency Error
Phase Error
PA Ramp
Modulation Spectrum
RF Power Steps
Timing Advance
Receiver BER Based RX Tests (RXQUAL RXLEV)
BER Based Sensitivity
Testing the following GSM functionality verifies proper network communication.
