Bluetest, Anritsu team for OTA measurement of WiFi 6E
Swedish WiFi wireless test specialist Bluetest has teamed up with Anritsu on a test system for over-the-air measurement of the latest WiFi 6E technology.

The combinatin of Bluetest's reverbation chamber and Anritsu test ssytems provides a complete WLAN Over-the-Air (OTA) test solution capable of transmit power (TRP) and receiver sensitivity (TIS) measurements on devices and access points. Measuring the OTA performance in life-like, but repeatable conditions, enable manufacturers of WLAN equipped devices, including IoT and smart home appliances, to optimize the radio performance.

This builds on an existing relationship for testing 5G cellular systems. 

Bluetest has upgraded its reverberation test systems with an increased default frequency coverage for the latest 802.11ax standard that reaches up to 7.125 GHz range with larger 160MHz channels.  The compact RTS25 chamber is upgraded by adding the new 6-7.125 GHz band. This chamber is primarily targeting the buzzing WLAN and Bluetooth industry. The RTS65, as well as the larger RTS85 and RTS95 now feature 4x4 MIMO support for frequencies all the way up to 12 GHz, in addition to previously released 5G FR2 packages with 2x2 MIMO support up to 43.5 GHz.

The Anritsu Wireless Connectivity Test Set MT8862A is optimized for stable and reliable connections with wider dynamic range, even in a faded environment such as in the Bluetest reverberation chamber. It is now updated with a new radio module adding support for the 6 GHz band and the 160 MHz channels, in addition to the already supported 2.4 and 5 GHz bands. The test setup is easily expanded to support 2x2 MIMO measurements using two MT8862A units.

“Increasing the default frequency range from 6 to 12 GHz with full support for multiple 4x4 MIMO carriers means we are fully prepared for continued evolution of the WLAN and 5G standards and shows the strength of our flexible product design,” said Bluetest Product Manager Klas Arvidsson.

“Expanding to 6 GHz band spectrum is expected to bring new services and it will require concrete performance evaluation to prevent issues regarding to new challenges,” said Keita Masuhara, Product Manager, IoT Test Solutions
