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 4×4 MIMO support for frequencies all the way up to 12 GHz, in addition to previously released 5G FR2 packages with 2×2 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 2×2 MIMO measurements using two MT8862A units.

“Increasing the default frequency range from 6 to 12 GHz with full support for multiple 4×4 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 Div., Anritsu.  “Anritsu has been working with Bluetest to provide valuable solutions for OTA RF performance evaluation. I am convinced that the new measurement system will contribute to efficient performance testing.”

The Anritsu MT8862A as well as all Bluetest chambers with the extended operating frequency range are available for order, and upgrade packages are offered for already installed systems. The updated Bluetest chambers are accompanied by corresponding upgrades to the line of accessories, such as reference antennas, ISS11 Attenuator System and ISS11 Instrument Switch.
