Note: QA is an ongoing
process based on random

120dBm. Take more
for what a marginal / poor signal would be.
Note: The response to AT!DACGPSCTON for a good connection should show CtoN within
58 +/- 5dB (preliminary value) and Freq (frequency offset) within 100000 Hz +/- 5000 Hz .

Quality assurance testing

The quality assurance tests that you perform on your finished products should be
designed to verify the performance and quality of your devices.
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 trans-
mitting within product specifications
• RF sensitivity tests
• UMTS:
· 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 Sierra
Wireless
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] AirCard / AirPrime UMTS Devices Supported AT
Command Reference (Doc# 2130617) and [3] AirPrime MC8xxx Embedded
Modules Extended AT Command Reference (Doc# 2130616).
