Implementing a carrier-grade Wi-Fi network is a challenging task. The network is expected to operate in extreme temperature and humidity conditions, provide highly reliable and secure data links to all customers, provide a centralized NMS, and interface to the operator's authentication and billing infrastructure. NextWave Wireless' Wi-Fi network has been designed to support all of the above carrier-grade features. In addition, mesh technology has been demonstrated to provide a cost-effective and survivable backhauling solution. Adaptive antenna technology has been demonstrated to improve the range and throughput of Wi-Fi BSs, thus reducing capital expenditure (CAPEX) and operational expenditure (OPEX) of the network and providing a competitive solution versus other carrier-grade Wi-Fi networks.
