Broadband Mobility Solution Requirements
– High capacity bidirectional throughput– Continuous connectivity in speeds– Quality of Service guarantee– Scalability– Reliable and robust
RAD ISM 01/2011 Slide 4
• Satellite
Broadband Mobility TechnologiesAvailable 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
• Requires outdoor access-point every few 100m• Limited drive speed, less than 90Km/h• Problem to stream Video due to Multicast limitations• High CAPEX

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 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

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
