ADC announced that its InterReach Fusion distributed antenna system (DAS) was deployed in a major airport and three hospitals to extend WiMAX coverage and capacity.
While ADC didn't announce the operator, the company's references to the largest WiMAX operator in the U.S. makes Clearwire the defacto choice. ADC said its InterReach Fusion system has been installed in Washington Reagan National Airport, and in VA hospitals in Dallas, San Antonio, and Temple, Texas.
The system employs 2x2 MIMO technology to increase signal quality and double throughput, ADC said. Its DAS system simplifies MIMO deployments for WiMAX and LTE because it can drive both MIMO antennas from each remote antenna location with one CATV cable. ADC said systems based on heavy coaxial cabling require separate cables for each antenna.
ADC said system performance tests have shown that its DAS delivers WiMAX access speeds of 13 Mbps upstream and 28 Mbps downstream.
"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.
