CTIA has officially authorized Elite to perform testing on behalf of the Wi-Fi Alliance and CTIA for Over-The-Air (OTA) conformance. This testing is required by participating cellular operators before a cellular-enabled device can utilize their networks.
The primary tests performed in Elite’s OTA chamber are Total Radiated Power (TRP) and Total Isotropic Sensitivity (TIS). These measurements provide the data that network operators like AT&T, Verizon, Sprint, T-Mobile and others require before a cellular module can connect to their network.
Additional cellular operator measurements may include radiated spurious emissions, SIM electrical, converged device de-sense, interoperability and field test.
For products with cellular transceiver modules, CTIA OTA testing is an important final step before the product can reach the market. For first-time cellular radio module integrators the requirements for TRP and TIS can be challenging. To ensure successful integration, Elite engineers work with clients from the early stages of product development to successfully complete OTA testing.
