Advanced IP Call Monitoring and Analysis Solution for 5G and LTE Protocols

GL is pleased to introduce the latest edition of our Newsletter, showcasing our advanced all-IP network monitoring software - PacketScan™ which captures and monitors live signaling and traffic over IP (IPv4 and IPv6). The application can decode, segregate, and troubleshoot network problems for all VoIP and Wireless protocols over IP networks.

5G and LTE Protocols


GL’s PacketScan™ software is a comprehensive tool for capturing, categorizing, monitoring and collecting statistics on various IP calls. This software excels at decoding VoIP and wireless protocols, providing detailed Quality of Service statistics for voice calls. PacketScan™ offers detailed insights into wireless protocols such as 5G, LTE, and IMS, allowing users to monitor live conditions or analyze historical data to understand network performance and operation. PacketScan™ can intelligently build call detail records, save and playback voice calls, and visualize the data.

For capturing traffic at high data rates, GL offers PacketScan™ HD, a high-performance network monitoring appliance for performing lossless packet capture over 1 Gbps, 10 Gbps, 40 Gbps, and 100 Gbps Ethernet / IP networks. It uses dedicated hardware with specialized Network Interface Cards along with PacketScan™ software for performing the packet captures.

PacketScan™ includes the Packet Data Analysis tool allowing users to monitor live IP or TDM networks including capture, analysis, and reporting of every phone call in detail. It also provides graphical presentation of analysis, including ladder diagrams of call flows.

PacketScan™ can seamlessly transfer captured data to GL's centralized database and dashboard, known as NetSurveyorWeb™. This platform offers a user-friendly web browser display for remote access to analyze the captured calls at multiple probe locations.

Efficient 5G Traffic Capture and Analysis

GL’s 5G Protocol Analyzer offers comprehensive monitoring capabilities for 5G networks. The 5G Protocol Analyzer captures, decodes, and collects statistics over the N1N2, N4, N8, N10, N11, N12, and N13 interfaces, providing valuable insights into core network performance and behavior.

The 5G Protocol analyzer features a user-friendly GUI that allows users to easily navigate, and view captured end-to-end signaling traffic. It also supports a wide range of codecs, including AMR WB, EVS, OPUS, and generates detailed call reports.

Comprehensive LTE Network Analysis with PacketScan™

GL's LTE Protocol Analyzer captures and monitors real-time signaling and traffic on LTE networks. The application segregates, monitors and collects statistics on all calls and can test eNodeB or UE over various interfaces, including S1, S3, S4, S5 (or S8), S6a, S10, S11, S13, and X2.
