AirPrime EM9190 Hardware Integration Guide
RF Specifications
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.

ierra 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.
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 definitions for supported RATs:
UMTS bands
— sensitivity is defined as the input power level in dBm that produces a BER (Bit
Error Rate) of 0.1%. Sensitivity should be measured at all UMTS frequencies across each band.
LTE bands
— sensitivity is defined as the RF level at which throughput is 95% of maximum.
5G NR Sub-6G bands
— sensitivity is defined as RF level at which throughput is 95% of
maximum.
