Problem

Much of the world still doesn’t have access to the internet. Some parts never will due to economic conditions, lack of resources, and lack of local technical expertise. Other parts lose internet access due to natural and man-made disasters.

Our Solution

Rather than transporting internet data over data channels, we physically transport the data using existing physical transportation methods, such as buses, trains, delivery vehicles, mules, etc. We call this Disconnected Data Distribution (DDD). We don’t require any new infrastructure or equipment. We use existing Android phones and USB keyfobs. Our solution is completely software-based and does not require new equipment or modifications to existing Android phones. Users simply install our Android apps on their phones. Our solution complements other solutions, such as long-distance Wifi and satellite internet, to bring internet services to the rest of the world.

How I built it

The Android Applications are written in Kotlin leveraging Jetpack Compose UI. Read the engineering blog about the process of migrating the Android User Interface layer from Java to Kotlin here: https://tinyurl.com/kotlindddmigration

What's next for Disconnected Data Distribution (DDD)

We are now exploring Kotlin Multi-Platform (KMP) to build a modular application that supports Android and iOS to be compatible with DDD by leveraging the new Wifi-Aware API framework.
