Satellite Communications

Introduction

• 25 billion IoT devices are projected by 2030.
• Terrestrial networks alone cannot support this vast number of devices.
• Only about 10% of Earth's surface has access to terrestrial connectivity services.
• Satellite communications can provide coverage to these unserved areas.
• The global satellite IoT services market is expected to reach $5.9 billion in 2025.
• This represents a dramatic tripling of satellite IoT devices and applications within the next three years.

Non-Terrestrial Communications

• Mega-LEO Satellite Systems
• CubeSats
• High Altitude Platforms (HAPs)
• Unmanned Aerial Vehicles (UAVs)
