On February, 2012 I attended an event organized by Orange labs in Egypt. The event was entitled "Mobile for the poor, a luxury or necessity?"
Problem: They speakers introduced the problem of no technology in rural areas in Egypt and Africa, where people don't enjoy even connectivity by mobile phones.
Goal: With the bless of being an engineer, we should use our technology knowledge to help rural areas to enjoy mobile connectivity. This will improve their living, and health.
