Network Diagnostics

Whether you are developing a new network element or testing your live network, you need to be able to troubleshoot any problem and correct it as quickly as possible. With the increasing data rates and amount of information exchanged through the network, the chances for error are greater than ever as are the consequences for your business of a poor service delivery.

In 3G and LTE architecture, Core and Access networks are changing dramatically in all aspects (transport layer, control- and service-plane), thus  impacting the test methods and strategies that can be applied. Compared to legacy networks architecture, much of the traditional access network functionality (packet scheduler, QoS, authentication, traffic management, etc.) is moved into the edge of the network, with NodeB and eNodeB becoming the center of test activities.

Unfortunately UTRAN and E-UTRAN were not designed to be monitored and they present a significant level of complexity to network element developers and maintenance and optimization engineers. The ability to monitor and analyze critical interfaces such Uu, Iub, Iur, as well as the possibility of correlation with other network interfaces, enables faster and more accurate troubleshooting of network elements and service problems, resulting in rapid isolation of root causes and elimination of performance issues.

For more than two decades, Tektronix Communications’ network diagnostics solutions have helped equipment manufacturers and mobile operators around the world understand and meet the challenges posed by the development and deployment of new generation wireless communication technologies, enabling the successful development of standards such as GSM, GPRS/EDGE, UMTS, mobile WiMAX, Femto and LTE.

Our industry-leading protocol decoding engine together with first-to-market applications such as multi-interface call trace, automated network topology discovery, and KPI trend analysis provides operators and equipment manufacturers with the right set of tools to quickly solve issues related to the development, roll out and maintenance of new and legacy wireless communication technology.
