Gaithersburg, Maryland, USA - July 11, 2023 - GL Communications Inc., a global leader in telecom test and measurement solutions, addressed the press regarding their new 5G protocol analysis tool. GL’s 5G Protocol Analyzer enables real-time monitoring and capture of 5G network traffic, allowing you to effortlessly gather and analyze data across the network.

Overview

“GL's 5G Protocol Analyzer offers comprehensive monitoring capabilities for 5G networks. It captures, decodes, and collects statistics over the N1N2, N4, N8, N10, N11, N12, and N13 interfaces, providing valuable insights into network performance and behavior”, said Vijay Kulkarni, CEO of GL Communications.

The 5G Protocol Analyzer is an optional application for PacketScan™. PacketScan™ is a protocol analysis software supporting a large range of protocols and codecs. PacketScan™ is deployed on Windows® PCs and uses the host PC’s network interface card to capture Ethernet / IP traffic. The PC should be connected to a network tap or a monitor port on a switch. PacketScan™ can also open packet captures offline and intelligently build call detail records, compute statistics on the calls, create graphs and ladder diagrams and more.

PacketScan™ includes the Packet Data Analysis (PDA) tool allowing users to monitor live IP/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.
