As 5G networks begin to proliferate indoors, Keysight Technologies has introduced a backpack set-up for walk-testing them. The new Nemo Backpack Pro is aimed at benchmarking 5G New Radio end-user experience across multiple mobile operators’ 5G networks in airports, arenas, enterprises and other indoor environments, the company said. It can fit up to 18 devices plus 1-2 scanning receivers in a carbon-fiber internal structure plus a backpack; Keysight says that the system is designed so that it “does not add over-the-air … path loss to measurements” and claims it is also the lightest available backpack testing solution.
