Blue Team Example

Problem:

• Communication loss after a disaster
• Relief workers can't coordinate with people on the ground
• Survivors can't communicate to share resources

Concept:

• Mobile device mesh networking
• Use app for cell-to-cell communications

Blue Team Process

1. Understand the problem

• How long was the "dark period"? 72 hours (Tacloban, 2013)
• What fraction of the towers are down? 100% (Tacloban, 2013)
• How many people have mobile phones? Nearly 100%
• How long do those mobile phone last (battery life)? 8 hours

2. Innovate potential concepts
 

3. Asess physics - Does the concept work?

• Link budget makes sense?

Yes, at ranges of ~100m (802.11a)

4. Design Architecture - Can the conept be practically engineered?

• Population density sufficient?

Yes, for 1000-20000 per km (Rutland VT to Mumbai)

5. Rapid Demo

• Can we show it works?

6. Prototyping

• Develop field capability?
