The Rohde & Schwarz CMW290 is a functional radio communication tester engineered for RF and protocol verification of wireless devices and integrated modules across IoT, consumer electronics, and enterprise applications. It delivers non-signaling and real-time base station emulation across cellular (GSM, WCDMA, LTE, LTE-M, NB-IoT), WLAN (802.11a/b/g/n/ac/ax), Bluetooth (Classic and LE 5.0), GNSS, ZigBee, and WiMAX standards. The instrument performs RF preconformance testing, IP application validation, data throughput measurement, and user experience simulation under realistic network conditions—making it suitable for development, production, service, and logistics environments.
