Model 2100D Wireless Test Lab

Ultra-compact design for prototype and production testing.

The Model 2100D is a compact measurement system designed to make Over the Air (OTA) measurements on wireless devices. It is a scaled down version of the popular CTIA−certified Model 3100 WTL. While not meeting the current range length requirement of the CTIA Test Plan for Mobile Station Over the Air Performance, it does provide measurement uncertainties that are consistent with CTIA requirements in a small, mobile chamber that requires no facility modifications.
