The Uplink
- Transmit voice or data on licensed frequency
- Aim the handset for line of sight
- Connect directly to an orbiting satellite
- Skip every local cell tower entirely
Satellite Relay
- Satellite receives the incoming signal
- Amplify the weak transmission
- Shift frequencies for the downlink
- Relay the signal back toward Earth
Ground Gateway
- Downlink to a network gateway station
- Terminate traffic at controlled facilities
- Enforce strict access control here
- Hand off to the wider network
Final Delivery
- Route the call through telecom networks
- Use the internet for data traffic
- Reach the recipient anywhere on Earth
- Complete the loop in seconds
Orbit Types
- LEO sits low for minimal latency
- MEO balances latency and coverage
- GEO appears fixed for wide coverage
- Pick the orbit to fit the mission
Why It's Secure
- Encrypt traffic at the air interface
- Avoid monitored switching centers
- Reduce exposure to operator gateways
- Force interception to be costly and complex
Stay Resilient
- Operate independent of local networks
- Hold connectivity through disasters
- Communicate during conflict or blackout
- Keep a backup power source ready
