Wireless Network Monitoring and Troubleshooting

Cellular networks are constantly evolving, and the service providers require comprehensive test solutions that can encompass all the test requirements - monitoring, troubleshooting, quality analysis, and reporting in order to deliver an optimized network for the customers.

Rolling out new technologies such as LTE, Advanced LTE, WiMax, 3G, and Broadband Internet requires effective methods to test voice and data quality. The probes deployed for testing must be network and device independent, and centrally controlled and monitored real-time. GL’s next generation Wireless Voice and Data Test Solution provides this flexibility of connecting to and between any network, any service, and any interface with centralized access to perform numerous analytical measurements (POLQA, PESQ, HTTP / TCP / SMS tests, and many more).

Case Study #2
Next Generation All-IP Network Monitoring

All carriers are rolling out services, including voice, video, fax, and data via packet networks. There is need for a single tool that provides comprehensive analysis and monitoring capabilities - whether for VoIP, FoIP (Fax over IP), video, or wired and wireless traffic and signaling. Also, if such a tool provides Quality of Service (QoS) and centralized Network Surveillance Solutions with multiple Probe locations, then customers are afforded a one stop solution for performance analysis of their IP networks.

GL's PacketScan™ and NetSurveyorWeb™ have been enhanced to provide such integrated and comprehensive All IP Network Analysis and Monitoring Solutions. PacketScan™ is a powerful software tool that captures and monitors live signaling and traffic over IP - almost all protocols from SIP,RTP, to LTE and Voice over LTE supported for troubleshooting network problems.

Setup a complete virtual real-time wireless network in your lab by simulating signaling and traffic behavior between different nodes of the network. Study real-time call and traffic behaviors, network response against protocol modifications, and impairments using GL’s Wireless Lab Suite. This test suite is ideal for complete simulation of 2.5G, 3.5G, and 4G networks. Case Study #3

Case Study #4
Test End-to-End Inter-Connection between Hybrid Networks

Successful inter-working of different core networks, be it IP to TDM, IP to PSTN, or TDM to TDM is critical for any service deployment. You should be able to setup a flexible test system that can perform automated loopback testing with different test plans, and assess the signaling and traffic behavior over interconnecting switches, hubs, and other network devices. GL’s MAPS™ is a highly recommended test suite for testing such hybrid networks as it covers wide variety of protocols from LTE, Diameter, UMTS, SIGTRAN, CAS, ISDN, and SS7. The tool also provides automation capability, and unlimited ability to edit messages and control scenarios (message sequences).

Testing system performance under realistic network conditions requires the introduction of impairments seen in the real-time networks. GL’s MAPS™ has a powerful protocol engine which can understand and decode protocol message, and also perform packet level fault insertion. It provides a fine control over any parameter in the protocol field. Case Study #5
