ADC has announced that its InterReach Fusion distributed antenna system (DAS) has been deployed to extend WiMAX coverage and capacity inside a major airport and three hospitals. As the only wireless operator-certified DAS for WiMAX use, ADC's InterReach Fusion solution will play a major role in bringing in-building WiMAX services to worldwide markets.

Deployed at the request of the largest WiMAX operator in the United States, the InterReach Fusion system has been installed in Washington Reagan National Airport, and in VA hospitals in Dallas, San Antonio, and Temple, Texas. The systems use 2x2 Multiple Input/Multiple Output (MIMO) technology to increase signal quality and double the throughput. Densely populated areas will require smaller cells to provide the needed uplink performance.

ADC's InterReach Fusion system simplifies MIMO deployments for WiMAX and LTE because it can drive both MIMO antennas from each remote antenna location with a single CATV cable. Systems based on heavy coaxial cabling require separate cables for each antenna. ADC system performance tests have shown that the InterReach Fusion system delivers WiMAX access speeds of 13 Mbps upstream and 28 Mbps downstream, or roughly twice as fast as many of today's 2G and 3G technologies.

"WiMAX uses high frequencies that attenuate quickly, so an in-building wireless solution that supports MIMO is essential for indoor coverage," said John Spindler, vice president of product management at ADC's Network Solutions business unit. "With these deployments and others in the pipeline, ADC adds WiMAX to the services it supports for major mobile operators worldwide."

ADC's InterReach Fusion system is among the most scalable and high-performance in-building DAS products on the market. It supports any mobile service, including GSM, CDMA, EV-DO, EDGE, HSPA, LTE, and WiMAX, so it is ideal for mobile operators or building owners who need to support 2G, 3G, and 4G technologies.
