K2Air - LTE Uu Monitoring Probe

Full insight on all layers of Uu interface allowing advanced LTE/EPC Troubleshooting.

Your Challenges

Operators need to speed up 4G LTE rollout. They also need to improve QoS by reducing the time required to identify issues and diagnose root causes. They need the ability to identify, verify and adjust default network parameters as quickly as possible. It’s important to have the ability to quickly determine whether 4G QoS issues originate in the air-interface/access network or within the EPC network. Operators need to improve end-to-end visibility of network performance through user plane correlation across whole LTE/EPC network. Operators also need to correlate user plane KPIs across both wireless and wireline LTE/EPC interfaces. The new radio access technology used in LTE requires new approaches to QoS analysis. For example, operators need a way to analyze the QoS interdependencies between the PHY/MAC and the service layers.

How We Can Help

The K2Air LTE air interface monitoring probe provides real-time, promiscuous mode, air interface monitoring via the CPRI interface. The K2Air LTE probe is seamlessly integrated into the Network & Service Analyzer (NSA) suite of fully automated software applications for troubleshooting and optimization of mobile networks and services. Carriers and network equipment manufacturers can achieve a 360°, end-to-end view of the LTE network and services. The K2Air LTE probe’s real time promiscuous mode air interface monitoring capability provides full insight into all layers of the Uu interface by capturing in real time critical information about the Physical and MAC layers required for detailed QoS analysis, including vector, spectrum and interference analysis. K2Air LTE probes and NSA software provide full coverage of all key LTE and EPC protocols, enabling full correlation of events and data across all interfaces, including Uu and EPC. The spectrum and vector analyzer modules provided by K2Air allow accurate and fast investigation of physical layer issues.

 Features and Benefits

  • LTE wireless and wireline interface correlation enables system verification in the shortest possible time, compressing the testing cycle during eNodeB development and system integration.
  • LTE real-time analysis and decoding for the LTE Uu interface (UL and DL) provides a drastic reduction of time required for Uu functional verification, compressing the eNodeB development testing cycle.
  • LTE multi-UE Support for Uu monitoring enables realistic traffic conditions to be tested in the lab to ensure product stability. Capacity and performance figures provided by suppliers can be validated prior to rollout.
  • Uu analysis dashboards provide a 5-in-1 solutions approach with built-in layer1 through 7 monitoring and troubleshooting delivering deeper analysis of the Uu interface.
  • Advanced KPI analysis enables users to analyze KPIs with different dimensions in order to compare performances based on different network elements, UE types, firmware versions, calls and times of occurrence. Time to information on more than 600 KPIs is substantially reduced.

4G Deep Dive Troubleshooting

K2Air probes provide monitoring and full correlation of both user plane and control plane traffic from air to LTE to core network interfaces, enabling 4G deep-dive troubleshooting on all LTE/EPC interfaces. Users can trace subscribers’ user plane and control plane traffic, both in real-time and offline, over multiple interfaces and network elements. This makes it possible to diagnose network issues from symptom down to root cause much faster and more easily than in the past, dramatically improving network testing efficiency. Network equipment manufacturers (NEMs) can release their LTE projects and operators can validate new products and software and launch 4G in less time than ever before. NEM development teams can meet their project targets by launching new 4G products earlier and with lower development costs. Mobile operator field engineers can reduce the time needed to troubleshoot LTE network elements during field trials and rollou
