Elite is expanding in a significant way to bring enhanced wireless testing services to manufacturers who are integrating wireless connectivity with their products. Our new Wireless and Antenna Testing capabilities include a fully-anechoic CTIA-compliant chamber that will measure the Over-The-Air (OTA) performance of cellular, WiFi, and Bluetooth transceivers. Download our “Guide to Antenna and OTA Measurements” for everything you need to know about key antenna performance metrics.

Why does a manufacturer need to test in a CTIA-compliant OTA chamber? 

Here are a few ways this new resource can help make a better wireless or IoT product:

First of all, in order to have a good wireless device, you need a good antenna. If your antenna is not designed efficiently then the transmitter has to deliver higher power to the antenna terminals to achieve the range and distance for the application. Driving the transmitter at higher power means more draw on the system power supply which in turn increases the heating of components and reduces the battery life for portable devices. With Elite’s new OTA chamber, engineers can easily visualize the antenna radiation in 3D and then design antenna elements and placement within the end product to achieve optimal performance. 

A wireless device’s receiver relies on the antenna to capture very weak RF radiated signals and then convert them into voltages at the receiver front end. Improperly placing the antenna in a manner that couples noise to the receiver will dampen the receiver sensitivity and negatively impact wireless communications. Elite’s OTA chamber provides the tools to optimize the placement of the antenna relative to the enclosure and the supporting digital circuitry to maximize the receiver’s sensitivity. Highly sensitive receivers extend the transmission ranges, enable higher data throughput, and provide greater communication reliability. 

The Elite OTA chamber is also used to evaluate Total Radiated Power (TRP), Total Isotropic Sensitivity (TIS), and Relative Sensitivity on Intermediate Channels (RSIC). These measurements are key performance metrics for cellular industry network operators such as ATT, T-Mobile, Sprint, and Verizon. With this new fully-anechoic antenna chamber, Elite clients integrating cellular radios can save time and cost by testing their devices in advance of formal compliance at a certified CATL Lab.
