Rohde & Schwarz will be demonstrating its CMW500 wideband radio communications tester at Mobile World Congress. This multistandard platform performs RF, protocol, performance and application tests on wireless devices for LTE (FDD and TDD), WCDMA, HSPA+, GSM and CDMA2000. The R&S CMW500 can also test the handover between these technologies. A major topic for the industry will be the rollout of voice services in LTE networks. To support these services, wireless devices will use the new voice over LTE (VoLTE) technology. This will present a major challenge for network operators and manufacturers of wireless devices. To help them meet this challenge, Rohde & Schwarz offers a new test solution based on the R&S CMW500 and the R&S UPV audio analyser which allows signalling and audio quality tests for VoLTE. A new test solution for WLAN-RF and end-to-end data testing on wireless devices is also available.
Rohde & Schwarz will present what they claim is the first universal platform that allows manufacturers of wireless devices to precisely test video and audio interfaces. This all-in-one solution for development and production measures all protocol layers and media content. The primary focus is on mobile high definition link (MHL). This new interface standard is ideal for high-resolution video content that is transferred via LTE. It also offers a direct interface to connect a tablet PC, smartphone or other wireless device to a high definition multimedia interface (HDMI) device.
To satisfy test requirements for location based services (LBS), Rohde & Schwarz is introducing the universal, scalable R&S TS8980LBS test system. LBS conformance tests, such as SUPL2.0, can be performed with this system. In addition, specific test solutions for network operators can be implemented. The test system integrates the R&S CMW500 as the system simulator and the R&S SMBV100A as the satellite simulator. The R&S SMBV100A signal generator supports GPS, Galileo and Glonass. The R&S TS8980LBS also automates complex test sequences.
For MIMO-specific measurements in LTE networks, R&S will present an updated version of its ROMES4.65 drive test software. This allows network operators and infrastructure manufacturers to obtain data to help determine where MIMO functions best in a specific coverage area and where investments in MIMO pay off. Together with the new software, the R&S TSMW drive test scanner not only supports LTE, but also previous standards such as UMTS, GSM and CDMA. It also covers all frequency bands from 30 MHz to 6 GHz.
