Additionally Verkotan has a tailored service called RF Modification. It is a test solution for 4G modem performance testing of smartphones, and now also for testing 5G modems in 5G phones, hotspots, handsets and so on. The modification is done by bypassing antennas of the phones or other devices with coaxial cables. Verkotan tests and identifies technologies and frequency bands that are functional via each cable. After this the modem performance can be easily tested without the impact of antennas.
“We tested throughput performance rates of a 5G smartphone. The test was made in collaboration with Anritsu using their Radio Communication Test Station MT8000A. We achieved throughput in the order 180 Mbit/s in SISO mode, 360 Mbit/s in 2x2 MIMO mode and 720 Mbit/s when 4x4 MIMO was used”, says Komonen
