Rohde & Schwarz to offer full 3GPP LTE, WiMAX, and mobile TV solutions at Mobile World Congress 2008
A product portfolio including T&M equipment for standards such as 3GPP LTE, HSPA+ or WiMAX, including MIMO functionality; compact, high-throughput solutions for production; and, mobile TV transmitters of all power classes, will be showcased by Rohde & Schwarz at the Mobile World Congress 2008 in Barcelona.
Multiple input multiple output (MIMO) technology uses multiple antennas on the transmit and receive side to increase data rates and transmission security. MIMO is intrinsic to many mobile radio standards such as 3GPP LTE, WiMAX, HSPA+ or WLAN 802.11n.
The R&S SMU200A high-end vector signal generator generates RF and baseband signals; the R&S AMU200A provides only baseband signals. Two signal sources and internal fading simulators can be integrated into both signal generators. Using a single box, engineers can perform measurements on 2x2 MIMO receivers including real-time fading on all four propagation paths.Both instruments support MIMO for the 3GPP LTE, WiMAX, WLAN 802.11n and HSPA+ standards.
For analyzing MIMO and LTE signals, Rohde & Schwarz's R&S FSQ and R&S FSG models enable detailed testing of the physical layer. Equipped with options for LTE and MIMO, the signal analyzers simultaneously process signals transmitted by the multiple antennas. They can also be used to determine whether pre-coding works for LTE signals across the different stages. Users in research and development can observe the performance of both the baseband and RF bands. In addition, the highly flexible analysis software ensures that engineers, developers and technicians can respond quickly to new developments of the standard.
In 2008, the development activities of mobile radio manufacturers will also begin to focus on the MIMO-based HSPA+ standard. Rohde & Schwarz will showcase its first solutions for RF tests at the Mobile World Congress and over the year will also launch protocol-test solutions for 3GPP HSPA+.
3GPP LTE moves ahead: protocol testing with Rohde & Schwarz In 2008, mobile radio manufacturers will conduct trials with 3GPP LTE-capable wireless devices and infrastructure. Protocol tests for wireless devices will be in great demand by research and development departments even earlier so that users can later transmit and receive data seamlessly. In addition to its existing RF portfolio, Rohde & Schwarz will therefore present initial solutions for protocol tests at the Mobile World Congress 2008. As 3GPP LTE test cases will be defined in the course of the year; the Munich-based electronics company will provide the required conformance-test solutions for these test cases.
WiMAX in production: maximum throughput and high measurement accuracy The measurement speed of the new R&S CMW270 WiMAX tester from Rohde & Schwarz is up to ten times faster than existing test solutions. This ensures maximum production throughput of WiMAX chipsets and mobile stations. Measurement accuracy has also been optimized with regard for stability and linearity to provide the best possible repeatability. The R&S CMW270 combines signal generation and signal analysis in a single box. Three interconnectable RF connectors in the RF frontend reduce test setup complexity, and this delivers significant cost, time and space savings in production and service applications. In addition, the R&S CMW270 is the first WiMAX production tester that is suitable for the integration of base station emulation (signaling mode).
