Mobile WiMAX is regarded as one of key technology options of third-generation (3G) and fourth-generation (4G) mobile network, where voice, video and data services all reside in one high-speed, spread spectrum radio access network. To satisfy the new requirements of monitoring ASN (Access Service Network) and CSN (Connectivity Service Network) of mobile WiMAX, a new generation of protocol analyzers is required. The Signaling Analyzer family of products is focused on solving the needs of higher intelligence and performance. The solution offers a breakthrough in troubleshooting methodology with a high- performance, client server, multiuser architecture and seamless drill down from statistics and call traces to messages and decodes. This solution allows full and uniform testing of network and individual call performance across all key interfaces of mobile WiMAX network. Agilent Technologies’ Signaling Analyzer WiMAX solution provides a distributed testing and analysis solution that maximizes the time and resources devoted to troubleshoot, optimize, performance benchmark, plan, install and maintain WiMAX networks. The solution’s architecture, design and structure are focused on drastically reducing capex and opex in organizations with responsibility for testing and maintaining mobile networks. The modular design and flexibility of Signaling Analyzer solutions allows multiple users and teams to identify problems and resolve faults quickly and effectively. All users in a fully distributed, multi-user architecture operate simultaneously, in real time, at high performance levels. This solution allows key personnel to see WiMAX network problems as they occur and turns what can be an overwhelming amount of data into actionable information and problem definitions.
