RAD ISM 01/2011 Slide 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 Ethernet Fiber Optic Ring RADview-EMS Mobile Radio ETX-26 Mobile Radio Airmux ETX-26

RAD ISM 01/2011 Slide 14 Train Side Architecture Train Antennas Dynamic Wireless Distribution System RAD Airmux Radio Backhaul Equipment Back Hauling WiFi Access Point Camera Video Surveillance and Access Equipment 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

RAD ISM 01/2011 Slide 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

RAD ISM 01/2011 Slide 16 RAD Mobility Solution Benefits 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

RAD ISM 01/2011 Slide 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
