Anritsu and Bluetest supporting OTA measurements on IEEE 802.11be (Wi-Fi 7) units


Anritsu and Bluetest mix their current product upgrades to create an Over-the-Air (OTA) measurement*1 resolution for verifying RF efficiency in tri-frequency bands of the most recent WLAN commonplace (IEEE 802.11be). This collaboration supplies clients with a WLAN check resolution able to transmit energy (TRP) and obtain sensitivity (TIS) measurements on IEEE 802.11be supported units. Measuring the OTA efficiency in life-like, however repeatable situations, allows producers of high-speed knowledge transmission units, together with high-end smartphones, AR/VR units and cloud gaming consoles, to optimize the radio efficiency and end-user satisfaction.

IEEE 802.11be is being standardized because the successor to IEEE 802.11ax (Wi-Fi 6/6E) and is focused to understand high-speed communications that considerably exceed IEEE 802.11ax. The usual is predicted to be a basic know-how supporting the most recent functions and companies, equivalent to ultra-high decision video streaming past 4K and AR/VR. Though the official launch of the usual is scheduled for 2024, product improvement primarily based on the draft commonplace is underway, and main corporations have already begun to carry their merchandise to market. IEEE 802.11be adopts modern applied sciences equivalent to 320 MHz bandwidth, 4096 QAM modulation and A number of RU, and a complete analysis of RF efficiency is required.

The Anritsu Wi-fi Connectivity Check Set MT8862A is devoted to the WLAN commonplace, therefore optimized for secure and dependable connections with wider dynamic vary, even in a pale surroundings equivalent to within the Bluetest reverberation chamber. It’s now up to date with a brand new radio module including help for 320 MHz bandwidth, along with the supported 2.4, 5 and 6 GHz bands. The check setup is well expanded to help 2×2 MIMO measurements utilizing two MT8862A models.

Bluetest Product Supervisor Klas Arvidsson says:
“The mixture of Bluetest reverberation chamber check system and Anritsu MT8862A gives a compact and quick resolution for evaluating WLAN gadget efficiency. Varied sizes of chambers, from the very compact, “fits-through-an-office-door”, RTS25 as much as the walk-in RTS95 chamber, caters for measurements on small, in addition to very massive WLAN units equivalent to tv screens or different residence equipment. It’s even attainable to measure wearables whereas utilized by an actual individual.”

Keita Masuhara, Product Supervisor, IoT Check Options Div., Anritsu Company, provides:
“IEEE 802.11be isn’t solely an extension of the bodily layer know-how, but additionally adopts modern applied sciences equivalent to Multi-link Operation*2, which allows simpler snug high-speed communication than ever earlier than by effectively utilizing three frequency bands concurrently. Nevertheless, particular efficiency analysis is critical to forestall issues and understand its full potential. Anritsu has labored with Bluetest to supply a useful resolution for OTA RF efficiency analysis. We’re assured that the brand new measurement system will contribute to environment friendly efficiency testing.”

The Anritsu MT8862A and all Bluetest chambers can be found for order, and improve packages are provided for already put in methods.
