Korea Telecom Tests ArrayComm's Wireless Broadband System

KT (Korea Telecom) completed the first phase of tests of ArrayCom's i-BURST broadband wireless system. ArrayComm uses spatial processing software and smart antennas to deliver data rates of up to 40 Mbps per cell, which could be shared between many simultaneous users at user data rates in excess of 1 Mbps in a fully loaded system. The South Korean field trials, which took place over several months, measured the system's data speed, range, scalability, capacity, and interoperability with Wi-Fi services. KT is planning a new wireless Internet business in the 2.3 GHz frequency band to complement its wireless LAN-based Nespot service. Technical achievements in the trials included proven, consistent individual data rates of 1 Mbps and 10 Mbps of total throughput in only 2.5 MHz of spectrum. KT and ArrayComm also showed seamless handoff between wireless LAN "Wi-Fi" coverage and wide area i-BURST coverage, as well as smooth interoperability with KT's Nespot VoIP commercial service. The next phase of testing will evaluate the i-BURST system's service capabilities using multiple cell sites in a dense urban environment.
