Hybrid Technology for Connected Vehicles
Catapult Open Agenda
• Challenges and Opportunities offered by Satellites
• Market Trend
• Key Enabling Technologies
• Hybrid Communication over 4G and 5G Networks
Catapult Open Challenges
Ubiquitous, high-speed connectivity for mobile users cannot be delivered by 4G/5G alone
• Coverage gaps
• Network Congestion
Examples:
• Vodafone UK LTE network:
1100TB/day across the UK
20M subscribers
Avg speed 5-10Mbps
• HTS satellite operator
54TB/day across the UK (5% of a single UK MNO)
1M subscribers
Avg speed 5-10Mbps
