Broadband Mobility Technologies Available
solutions

• Satellite

• 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

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 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

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
