Spirent 4G LTE Test Solutions

　　Most LTE deployments are likely to be upgraded, so LTE devices and services need to work seamlessly with existing network technologies. Consumers who choose LTE devices expect them to work perfectly from day one of service deployment, so the secret to success is comprehensive LTE testing and validation of network components and devices during the design, development and deployment phases. And all of this needs to be done as quickly as possible under tremendous time-to-market pressure.

　　Mobility

　　The desired end-user Quality of Experience (QoE) for services such as voice and video depends heavily on the ability of the LTE network and devices to support seamless intra- and inter-technology (UMTS, GPRS, CDMA, etc.) mobility. This complex set of scenarios must be tested in the lab prior to deployment.

　　performance

　　Multimode LTE devices must provide seamless performance on LTE, UMTS and/or CDMA networks while also supporting other signals such as GPS and Wi-Fi. While operator rates are increasing every day, the performance of multi-antenna MIMO implementations of the air interface is a critical factor in achieving this goal.

　　The components of the Evolved Packet Core (EPC) in LTE networks must have high capacity and excellent IP performance. This requires the use of a new generation of dedicated, highly scalable mobile core equipment, as well as strong IP expertise in the design and testing of EPC implementation projects.

　　Evolution of Mobile Backhaul Networks

　　As LTE cell sites require higher capacity, native Ethernet is used as the physical interface to connect and transport such services, so mobile backhaul networks must face major changes. Replacing TDM lines with Ethernet will mean striving to achieve higher timing and synchronization accuracy, which is the only way to minimize disruption to services and eliminate the risk of dropped calls.
