Wireless Mobility System

1. Wireless Mobility System

2. What is it? A solution that provides continuous broadband connectivity to a moving vehicle

3. High capacity bidirectional throughput Continuous connectivity in speeds Quality of Service guarantee Scalability Reliable and robust Broadband Mobility Solution Requirements

4. Satellite Broadband Mobility Technologies Available solutions • High monthly connection fee per Train, thousands of EU • Limited capacity, 2Mbps Downlink and 128Kbps Uplink • High Latency, unsuitable for Voice and Video applications • No coverage in tunnels and in northern countries • Limited capacity, segmented 3G coverage along the Railway • Practically low capacity, less than 3Mbps for entire Train • Unstable, many disconnects, unsuitable for Voice and Video applications • Cellular operators do not generally cooperate much • Cellular • 2/3G • Terrestrial • WiFi-Mesh • WiMax • Proprietary • Requires outdoor access-point every few 100m • Limited drive speed, less than 90Km/h • Problem to stream Video due to Multicast limitations • High CAPEX

13. Track side Architecture • Radio base stations along the rails (ranging in 3-10km’) • Protected backhaul of the base stations based on GbE ring over Fiber Optics • Support extreme environmental conditions • Central management solution Mobile Radio Mobile Radio Mobile Radio Mobile Radio ETX-26 ETX-26 ETX-26 ETX-26 Airmux Airmux Airmux Airmux RADview-EMS Ethernet Fiber Optic Ring ETX-26

14. Train Side Architecture • Radio Antenna in front of the train • Access points in each wagon with wireless mesh connectivity • Support for WiFi Internet service for the passengers • Support for Real time Video Surveillance cameras Train Antennas Dynamic Wireless Distribution System Back Hauling WiFi Access Point WiFi Access Point Camera Camera WiFi Access Point Camera RAD Airmux Radio Backhaul Equipment Video Surveillance and Access Equipment

15. Backhauling Solution Overview RAD has developed a true Mobility Broadband Solution: • Dedicated and robust wireless link to a mobile unit • Frequency: 5.x and 2.x multi band (Un-license bands) • Channel bandwidth: 10, 20 & 30 MHz • High capacity, up to 30 Mbps net aggregate throughput • Wide coverage, requires Base stations up to 10km apart • Continuous connectivity, both on-ground and underground • Very low latency, suitable for VoIP and video applications • Tested and approved up to 150Km/h, designed for higher speeds • Fast handoff between base stations to ensure uninterrupted service • Complies with the European railway standard EN50155, EN50121 • Overcomes the primary network bottleneck of backhaul to a moving unit

16. RAD Mobility SolutionBenefits • High Uplink/Downlink Throughput – Enables 2-way Broadband services e.g. High-Definition (HD) video traffic between BS and Train • Redundancy - Designed for complete system redundancy that guarantees continuous connection and operation • Sub-6GHz Frequencies Supported – Un-License frequency band • High bandwidth – 30MB aggregated bandwidth that can be defined as symmetrical or unsymmetrical

17. Case Study • Transferring real time video surveillance from trains to the control • VoIP from/to the driver • 2 ways metro Tunnels (18Km each) • 39 trains • 14 Cameras per train (2 per wagon) – each camera 1.5Mbps upstream • Full system Installation during Q3/2011
