To determine the extent of any receiver performance desensitization due to self-
generated noise in the host device, over-the-air (OTA) or radiated testing is
required. This testing can be performed by Sierra Wireless or you can use your
own OTA test chamber for in-house testing.
Sierra Wireless’ sensitivity testing and
desensitization investigation
Although AirPrime embedded modules are designed to meet network operator
requirements for receiver performance, they are still susceptible to various
performance inhibitors.
As part of the Engineering Services package, Sierra Wireless offers modem OTA
sensitivity testing and desensitization (desense) investigation. For more
information, contact your account manager or the Sales Desk (see Contact
Information on page 4).
Note: Sierra Wireless has the capability to measure TIS (Total Isotropic Sensitivity) and
TRP (Total Radiated Power) according to CTIA's published test procedure.
Sensitivity vs. frequency
Sensitivity is defined as the input power level in dBm that produces a BER (Bit
Error Rate) of 2% (GSM) or 0.1% (UMTS). Sensitivity should be measured at all
GSM / UMTS frequencies across each band.
For LTE bands, sensitivity is defined as the RF level at which throughput is 95% of
maximum.
Supported frequencies
The MC7304 supports:
• Penta-band LTE—See Table4-1 on page46.
• Penta-band WCDMA/HSDPA/HSUPA/HSPA+/DC-HSPA+—See Ta bl e 4 -3
on page 46.
• Penta-band WCDMA receive diversity
• Quad-band GSM/GPRS/EDGE—See Table 4-4 on page 47.
• GPS and GLONASS—See Table 4-9 on page 49.
