To achieve high quality of service, mobile networks must be tested throughout their lifecycle. This means verification of network functionality and quality at the R&D and deployment phases, but also across the live network. This kind of live network troubleshooting, for example at the base station, requires an easily portable solution that enables a field engineer to quickly identify and address any network issues that may arise. Service, support and field teams need a tool such as the TravelHawk, which works in a multitechnology environment, is easy to use, and—most importantly—reduces the complexity and the time spent on testing.
TravelHawk is a perfect fit for both network equipment manufacturers and operators for testing and troubleshooting networks at all stages of their lifecycle:
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, UMTS, GSM, 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 Analyzer Care key to keep your tool up-to-date.
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.
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.
With the Protocol Monitor application, transactions can be analyzed to the last detail in real time and from multiple interfaces simultaneously.
TravelHawk also boasts a unique OPEX-saving functionality that allows users to compare any call in extreme details against their own reference call. With one click from the Call and Session Analysis application or the Protocol Monitor application, users can compare detailed signaling of two calls to the information element level and see the different parameters or messages of signaling protocols—saving technicians time as they don’t have to spend hours locating the most hard-to-find mobile network signaling problems.
TravelHawk is designed with real-time telecom signaling analysis in mind. Real-time analysis can be done up to hundreds simultaneous calls and up to 10 000 calls at the time (round-buffer, oldest calls are removed). Intelligent filtering of connections and Iub user-plane data for example, allows physical-link monitoring with full line-rate throughput. TravelHawk is able to filter needed information from full physical links, e.g., the needed base stations or links with signaling data. For bigger data amounts, users can capture data with the recording capacity of up to 120 Mbit/s. Data can later be analyzed in post-processing mode. TravelHawk is not designed for packet network user-plane analysis. Please refer to TravelHawk Pro specification sheet for LTE and packet core user- and control-plane analysis.
