Testing
The following are some testing suggestions that can confirm that the antenna is interfaced
properly, and that the RF module is calibrated and performs to specifications:
•
Module registration on cellular networks
•
Power consumption
•
Originate and terminate data and voice (if applicable) calls
•
Cell hand-off
•
Transmitter and receiver tests
•
FER (Frame Error Rate) as an indicator of receiver sensitivity/performance
•
Channel and average power measurements to verify that the device is transmitting
within product specifications
•
RF sensitivity tests
•
RF sensitivity testing— BER/BLER for different bands and modes
•
Transmitter and receiver tests (based on relevant sections of the 3GPP TS51010 and
3GPP 34121 documents)
Suggested Testing Equipment
To perform production and post-production tests, you will require appropriate testing
equipment. A test computer can be used to coordinate testing between the integrated
module (on the development kit or host) and the measurement equipment, usually with
GPIB connections. The suggested setup includes a power meter to test RF output power
and a signal generator to evaluate the receiver.
Testing Assistance Provided by Lantronix,
Inc.
Extended AT commands have been implemented to assist with performing FTA GCF tests
and portions of CE Mark tests requiring radio module access. These are documented in
the [2] AirPrime EM75xx and EM/MC74x1 AT Command Reference (Doc# 41111748).
Lantronix, Inc. offers optional professional services based assistance to OEMs with
regulatory approvals.
IOT/Operator Testing
Interoperability and Operator/Carrier testing of the finished system is the responsibility of
the OEM. The test process will be determined with the chosen network operator(s) and
will be dependent upon your business relationship with them, as well as the product's
application and sales channel strategy.
Lantronix, Inc. offers assistance to OEMs with the testing process, if required.
