Radiated Sensitivity Measurement
A wireless host device contains many noise sources that contribute to a reduction in Rx
performance.
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 Lantronix, Inc. or you can use your own OTA test chamber for in-house
testing.
Lantronix, Inc.’ 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, Lantronix, Inc. 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 3).
Note: Lantronix, Inc. has the capability to measure TIS (Total Isotropic Sensitivity) and TRP (Total
Radiated Power) according to CTIA's published test procedure.
Sensitivity vs. Frequency
For 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.
For LTE bands, sensitivity is defined as the RF level at which throughput is 95% of
maximum.
