Spirent Communications plc has released new packaged configurations targeted at WiMAX and LTE developers for its Spirent SR5500 wireless channel emulator, which is used for testing wireless receivers. These new packages support bi-directional multiple-in, multiple-out (MIMO) and beamforming testing.

MIMO and beamforming are crucial aspects of next-generation wireless technologies, said Spirent. Both techniques use multiple antenna configurations to increase data rates, decrease operational costs, increase range or steer signals toward areas of high user density.

With the new Spirent SR5500 configurations, users can quickly and accurately validate the performance of even the most complex MIMO and beamforming implementations. The configurations also feature Spirent's exclusive Dynamic Environment Emulation (DEE) to perform a lab-based equivalent of mobility drive testing, including the scenarios recommended by the WiMAX Forum. Unlike drive-testing on live networks, Spirent said DEE offers repeatability and the flexibility to design and execute custom scenarios.

The Spirent SR5500 supports multiple emerging next-generation technologies. In addition to support for the new 700-MHz and 2.7-GHz bands, the SR5500 also offers fully independent RF channels for widely spaced Frequency-Division Duplexing (FDD) WiMAX applications. The advanced fading engine ensures accurate testing of technologies such as HSPA, EV-DO, E-UTRA (LTE) and WiMAX.

Pricing starts at $125,000 for the Spirent SR5500.
