1 Get the best performance from your LTE Network with MOBIPASS The most powerful, user friendly and scalable enodeb test tools family for Network Equipement Manufacturers and Mobile Network Operators

2 Network Equipement Vendors challenges The new LTE standard and architecture is a major technological breakthrough over previous 2G and 3G wireless networks. enodeb: the Critical Node for Network Validation and Optimisation The full IP architecture, higher throughput and the radio interface based on OFDMA/ SC-FDMA modulation introduce new challenges for R&D teams involved in development, testing and validation of 4G Networks. As in previous generations, QoE, QoS, stability, capacity and interoperability remain major area of concerns for the wireless industry, and now require new tools specifically designed for high capacity transmission over radio interface and packet oriented transmission schemes. The LTE network architecture moves a lot of the complexity and management down from the 3G RNC to the LTE enodeb, increasing focus on this node, which is essential for the performance of the LTE Radio Access Network.

3 MOBIPASS at the heart of LTE testing challenge The ultimate goal is to enhance the user experience by increasing throughput and reducing latency; increase Mobile Network Operators revenues by allowing more users and more services within the same spectral allocation. High Performance for high Capacity and Stability Unlimited Capacity with Scalable architecture Supports thousands of UEs with high data throughput and multiple cells Proven stability and endurance testing with multiple enodebs solutions MOB550 Uu X2 enodeb S1 MOB510 S1 Easy to use for high QoS Easy to construct complex test scenarios for more realistic behavior and better test coverage Easy to use tracing and debugging tools with automatic diagnostics on all interfaces Full visibility at any layer and at any time Same test environment for different tests types (sub-system, system, functional, load) Evolving with 3GPP for high interoperability Latest 3GPP release supported on time with software defined approach Hardware and software architecture supports long term improvement (LTE advanced) Easy transition to any 3GPP release (back and forth) for regression testing MOB560 = MOB550 + MOB510 + X2 enodeb High level of technical support for reducing time to market Local technical support Built-in support tools Highly reactive engineering teams Lowest CAPEX and OPEX for a controlled budget Same tool for both functional and load testing With our A la carte modular approach, pay only for what you need and when you need it MOB550 Family Multi UE emulator Thousands of UEs Multiple Cells Mobility Channel Emulator TDD, FDD, PMR Multiple bands and bandwidths 400MHz- 2.8GHz ( ) MHz MOB510 Family epc emulator Multiple MME, SGW, HSS, P-GW, emulation E-utran sharing Automatic mode IMS like Open API for End-to-End testing MOB560 Family H/eNodeB tester Full Wrap around (S1, Uu, X2) Intra and intercell handover CPRI or RF connections End-To-End testing, QoS, QoE

4 MOB550 FAMILY LTE Multi UE emulator The MOB550 series MOBIPASS -LTE UE Emulator removes the limitation on the number of UEs available to a test team; test that were previously possible with only a few UEs can now be performed with thousands of UEs. Multi UE Channel Emulator The MAC scheduler is a complex and essential component of the enodeb architecture. It runs proprietary scheduling algorithms responsible for providing the appropriate QoS and maximizing radio interface utilization. Full validation of the LTE enodeb is only possible by simulating real-life radio conditions and stresses that will be faced in commercial applications such as interference, fading, speed, packet loss etc. The LTE UE MOBIPASS -Emulator channel emulator is an integrated solution with a per UE behavior model that will stress the enodeb according to configured profiles. Global test scenario Example of Realistic traffic model 60 UEs in VoIP 20 UEs in web browsing UEs in = 3 Traffic classes Complex call profile generation for realistic traffic model Mobipass embeds a test scenario builder that allows the user to build multiple complex scenarios thus narrowing the gap between lab testing and field reality. Being able to accurately recreate real-life conditions during lab testing allows companies to reduce cost in deployment later on. The test scenario builder allows the user to build multiple classes of traffic, for instance, VoIP, , Web Browsing, Video, FTP, HTTP, etc. Each traffic class can then be defined with unique call profile, number of UEs, mobility conditions, UE call start distribution and other attributes. Thus thousands of UEs using different call profiles can provide an accurate representation of real-life users in the field using their phones in different ways. Powerful, easy to use debug and analysis environment To meet the quality requirements of commercial LTE networks, it is imperative to validate the enodeb and improve test coverage by applying test scenario that are very realistic meaning: multiple applications, full mobility and massive multi user load on a cell. Mobipass can be used at every step of enodeb design and validation from very detailed physical layer configuration all the way up to high level scenarios using the entire protocol stacks.

5 MOB510 FAMILY epc emulator The MOB510 series LTE epc MOBIPASS -Emulator removes the requirement of using a real epc for testing the functionality of the enodeb. A real epc is often very costly, complex to set up and may not support the same features as the enodeb under test as per the R&D roadmap.the MOB510 series testers features an advanced automatic mode that behaves like a real epc allowing S1/NAS responses to UE/eNodeB requests without having to manage a complex setup. Design or test teams working on particular sub-systems of the network such as UE, RRH, or enodeb and who do not have the need to write custom test scenarios to control the epc emulator can benefit greatly from this easy automatic mode. MOB560 FAMILY enodeb/henodeb tester The MOB560 series testers are a full wrap around solution emulating the three interfaces: Uu, S1 and X2, allowing for full control of the H/eNodeB. The MOB560 series includes all MOB550, MOB510 and X2 interface features on one unique test platform. Validation and integration engineers get full visibility and a rich debug environment to test the complete H/eNodeb solution. MOBIPASS Key Innovative concepts Modularity concept A la carte test configuration concept: the modularity of the Mobipass design and the upgradable approach allows any test team within the R&D organization to find the right configuration at the right level of investment. Always on trace concept Capturing and storing logs of LTE full stack protocols can become difficult to manage due to their sheer size when simulating multi-user traffic. To avoid handling large log files unnecessarily and help the user save time required to transfer and analyze logs, Mobipass is embedded with an innovative trace capability using a circular buffer. Aggregation concept Mobipass is composed of UE modules capable of emulating hundreds of UEs each. The flexible Mobipass architecture allows the aggregation of several modules in order to achieve the required number of UEs, data throughput, and increase the performance in line with the customer product roadmap. The aggregation concept provides a clear path to LTE Advanced and enables cost reduction at the same time. Functional and load test Functional testing allows the user to test the enodeb or parts of its sub-systems and verify that the product conforms fully to 3GPP specifications. Load testing on the other hand is focused more on the Key Performance Indicators and stability of the product under heavy stress load. The Mobipass series fulfills the requirements for both these different test paradigms.
