CETECOM, a world leading test laboratory, has selected Rohde & Schwarz (R&S), a global leader in wireless test solutions, to enhance their over-the-air (OTA) testing capabilities with a new test system that includes LTE multiple-input, multiple-output (MIMO) and 802.11n functionality. The TS8991 test system can perform OTA measurements for LTE MIMO in addition to all cellular 2G, 3G, and 4G technology standards. It is not only capable of performing the legacy IEEE 802.11 WLAN standards for a, b, and g, but is the first system in any 3rd party test labs worldwide capable of performing 802.11n WLAN OTA measurements. Unique to the system is its auto-calibration capability, which dramatically decreases system calibration time from hours to under 30 minutes, while achieving the same accuracy and repeatability in results.
With this new test system, CETECOM’s OTA testing capabilities are expanded to ensure compliance to the latest MIMO industry methodologies from CTIA, 3GPP as well as any operator-specific test plans. The R&S TS8991 OTA test solution was installed at CETECOM’s facility in Milpitas, CA.
