The Rohde & Schwarz CMW500 is the industry-standard Wideband Radio Communication Tester designed for fast, precise, and comprehensive testing of current and future wireless devices. Supporting a vast array of cellular and non-cellular technologies, from legacy 2G/3G to LTE, 5G NR, WLAN, and Bluetooth, it provides a flexible all-in-one architecture. The CMW500 serves as both a high-speed production tester (non-signaling) and a fully capable protocol tester (signaling/call box mode). Its dual-path configuration allows for parallel multi-technology testing, maximizing throughput and simplifying setup complexity in development, verification, and manufacturing environments.
