Keysight is supplying UC Berkeley researchers with test gear to advance over-the-air (OTA) measurement techniques for 6G, extending a line of university collaborations that test-and-measurement vendors have used to position themselves early in the next standards cycle.

The partnership, reported by industry publication Bisinfotech, centers on OTA testing — a method that validates radios by radiating signals through the air rather than through cabled connections. The approach matters for 6G because expected frequency ranges sit far above today's 5G bands, where connectors and cables introduce errors and antenna arrays become inseparable from the radio itself.

Why does over-the-air testing matter for 6G?

Each generation of mobile technology has pushed into higher spectrum, and each step has made conventional conducted testing less useful. At millimeter-wave frequencies already used in 5G, antennas are typically integrated directly onto chip packages, leaving engineers no port into which to plug a cable. OTA measurement captures the combined behavior of the antenna, the radio front end and the propagation channel in a single step.

For 6G, researchers are studying spectrum in the upper mid-band and sub-terahertz ranges, plus new antenna concepts such as reconfigurable intelligent surfaces. None of these can be characterized with legacy benchtop methods alone. That gap is why companies such as Keysight, Rohde & Schwarz and Anritsu have invested in OTA chambers, channel emulators and university research programs years before any 6G standard exists.

What is Keysight actually doing?

Keysight is enabling UC Berkeley's research into OTA test methods, according to the report. The company has a long record of this kind of academic engagement: its instruments already support 5G and Open RAN validation work at universities and standards bodies worldwide. Equipment makers typically treat campus labs as proving grounds where measurement techniques are refined ahead of commercial demand — a pattern that paid off during the 5G rollout, when OTA testing moved from research curiosity to procurement requirement.

No commercial 6G deployment timelines, contract values or throughput figures were disclosed in the announcement, and readers should treat any vendor framing about "advancing 6G" as early-stage positioning rather than product news. The relevant standardization work sits with 3GPP, which does not expect to begin 6G specification work in earnest until its Release 20 timeframe, with first commercial networks widely projected around 2030.

The bigger picture

Test equipment rarely makes headlines, but it quietly sets the pace of wireless development. Operators and chipmakers cannot certify devices they cannot measure, and measurement science for sub-terahertz spectrum is still immature. University partnerships like this one help vendors such as Keysight shape the eventual test methodology — and, by extension, the tooling that every 6G equipment maker will eventually need to buy.

For UC Berkeley, the arrangement gives researchers access to professional-grade instrumentation that would otherwise stretch academic budgets. For Keysight, it offers early insight into the measurement problems that 6G will create. Both sides gain, and the industry gains a clearer picture of how future radios will be validated.

With 3GPP's 6G study phase drawing closer, expect more of these vendor-university pairings in the coming year, as test-and-measurement firms jostle to define the methods by which the next generation will be judged.
