The last mile problem

Tanzania, like many African countries, suffers from the last mile problem: the cost of delivering connectivity to remote regions (where most people live) is just not worth it for traditional telcos.

Globally, this has left an estimated 4 billion people without reliable access to the internet, deepening the digital divide and worsening disparity.

Introducing Kajanjoo

Set deep in the heart of the Saadani National Park, Kajanjoo is a small but bustling fishing village, home to around 200 people.

Only accessible via dusty dirt tracks, perilously perched on the banks of meandering streams, its homes are built on stilts to evade the effects of seasonal floods.

The fishermen, whose hand-woven nets are cast from red sunrise to purple sunset, are hours from the nearest town where they can conduct their business. The same journey made by those who need to access basic healthcare and government services, and to simply check their messages.

Kajanjoo was left offline because mobile operators could not profit from connecting them. But this is where we’re different.

The World Mobile solution

The World Mobile Chain is a cost-effective and sustainable solution to bring even the most isolated of areas online.

Combining blockchain technology with renewable energy and unlicensed spectrums, we allow anyone to own and operate the key elements of our network and get connected.

Here’s how we did it in Kajanjoo.

The installation

• Foundations are set and let dry overnight.

• Solar panels and rechargeable batteries are installed.

• The WMC Air Node is erected along with a streetlight.

• The exchange box is configured.

• This is connected to backhaul infrastructure.

• The World Mobile network is up and running.

How it works

World Mobile’s network centre in Dar es Salaam utilises existing fiber capacity until around 65km from Kajanjoo. From there, we use spare wireless spectrum to create a point to point link to the village via 2 hops.

In the village, a radio link connects to the router. The router then connects to a WMC Access Point device inside the WMC Air Node.

The WMCAccess Point uses WiFi to allow villagers to connect their phone to the World Mobile network.

Outside of our network coverage, the Global SIM card gives villagers competitive rates on their calls, texts and data.

Online, for the first time

Villagers can now top up credit in the local shop, allowing them to make low cost local and international calls via the World Mobile application.

They can use data to access social media, world news and use messaging services like WhatsApp and Messenger.

Fishermen can send pictures of their catch to buyers in town, and arrange deals without having to even leave the village.

What’s more, as the Air Node is owned by the village, a percentage of the revenue generated from calls, texts and data gets shared with the community and goes back into the local economy.

But it doesn’t end there

Connectivity is just one part of the path to digital inclusion. Those that live in Kajanjoo now have the freedom to explore the social and economic benefits of having local internet. From developing online businesses, to accessing education and mobile banking, they can discover the opportunities that those in the cities take for granted.

Let's bring the whole world online.

Billions of people don’t have internet. By using unlicensed spectrum, blockchain technology and telecoms wizardry, we’re changing that.
