The mmWave-UPM Lab is a state-of-the-art 5G research facility specializing in FR2 over-the-air (OTA) testing, fully compliant with 3GPP conformance standards.

This unique UPM facility provides comprehensive OTA testing in accordance with 3GPP TS 38.521, covering both uplink and downlink directions: transmit power, power dynamics, signal quality, RF spectrum, Rx sensitivity, and adjacent channel selectivity, across a wide temperature range from –40 to 85 °C.

The mmWave-UPM Lab enables precise validation of next-generation user equipment under real-world and thermal stress conditions.
