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
• 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 operation
• Sub-6GHz Frequencies Supported – Un-License frequency band
• High bandwidth – 30MB aggregated bandwidth that can be defined as symmetrical or unsymmetrical
