Trials Show Feasibility of Wireless LMDS in Taiwan's Soon-To-Be Deregulated Telecom Market
In partnership with a Zhongyang University in Taipei and several third-party vendors, HNS demonstrated AIReach Broadband 9000's high-bandwidth capabilities with a variety of real-time applications including voice over Internet protocol (VoIP), Internet access, IP videoconferencing, local area network (LAN) interconnection PABX interconnection, and telephone access lines via wireless connections.
"We wanted to demonstrate that broadband wireless access in the LMDS bands is feasible in a country such as Taiwan, which is often subjected to heavy tropical rains, said Eric Wu, assistant professor of computer science and information engineering at Zhongyang. "We chose to test at 38 GHz, the high end of the LMDS frequencies, to investigate worst-case scenarios, and we found that the system performed at a range many times greater than had been speculated, offering comparable quality and stability to fiber and terrestrial infrastructures."
AIReach Broadband is a fiber-class wireless access system designed to offer high bandwidth services to business and multi-dwelling residential customers. HNS' second-generation, point-to-multipoint radio product integrates access for services such as switched voice, high-speed data—either circuit switched, time division multiplexer/multiplexing (TDM), or packet-based, frame relay, and asynchronous mode transfer. Using high spectral efficiency modulation, the system provides 45 Mbps of information in a 12.5 MHz radio channel. It also can be adapted to meet carrier needs.
"Given the success of the testing at the 38GHz frequency in Taiwan, we believe that HNS products in the 24 to 28 GHz bands will offer even greater range and capacity, thus driving costs down even further," Hsu said.
