TravelHawk: A Compact Unit Packed with Multiple Capabilities
The TravelHawk is the only portable protocol analyzer on the market that supports 2G, 3G and 4G technologies in one unit. Its small size makes it easy to carry, even as carry-on luggage on an airplane.
TravelHawk is a briefcase-sized PC equipped with the M5 Analyzer software. It allows real-time troubleshooting of multiple interfaces from LTE, UTRAN, GERAN, core and IMS networks in the lab or in the field. With automated configuration, TravelHawk is quick and easy to set up for analysis. Network traffic analysis is illustrated with clear, real-time graphics, and issues to be addressed are clearly highlighted. New functionalities are easy to install via a software update downloaded directly from the EXFO website. All you need is a valid EXFO Care subscription to keep your tool up-to-date.
Troubleshooting Applications
TravelHawk features intelligent data analysis applications that enable real-time multitechnology and multi-interface call and session tracing with real-time pre-filtering capabilities, KPI generation and QoS measurements—all with the capability to drill down into the details of the decoded protocols.
Signaling Tracing and Analysis
The Call and Session Analysis application is a key troubleshooting tool that allows you to quickly see if there are any problems in the network.
- Real-time tracing of calls and sessions over the monitored interfaces
- Complete correlation of intersystem calls between LTE, UTRAN, GERAN, core and IMS
- Real-time pre-filtering of raw data with any main UE or network-related value to see only the needed calls or sessions
- Overall status of the calls and sessions in one view; each transaction has its own line with illustrative phase icons
- Over 500 3G/2G/LTE information elements available for the calls/sessions; any piece of information can be used to filter data in the GUI
- One click to open full signaling details of a call, or save call/session-related data to a file
With the Protocol Monitor application, transactions can be analyzed to the last detail in real time and from multiple interfaces simultaneously.
- Message sequences for easy analysis of message flows
- Overall view of the network, with each event seen on its own line, along with its specific information and protocol content
- Easy access to complete signaling details for each event
- Correlated protocol messages between analysis views, making it easier to switch analysis to another view
- Layer details settings based on any stack, protocol, message or information elements to define what is displayed
- One click to open calls related to signaling
- Support for latest industry-standard specifications and vendor-specific implementations
Statistics
With TravelHawk, the Diagnostics Suite is a post-processing application that shows KPIs and QoS counters. It provides essential information on the overall performance of the network based on traced transactions, making it easy to analyze hundreds of thousands of calls or sessions quickly. The xDRs and KPIs are stored to a local database to allow analysis of large amounts of data.
- Visualization of transaction counters and KPIs from LTE and PS/CS core interfaces
- Distribution of failures sorted by reason in graphics
- Drill down to root causes and detailed analysis
