Motorola converted miners' walkie-talkies into two-way voice calls to the world above.

Thousands of mine workers in India work deep underground in the dark for over ten hours a day, and mobile phones are forbidden there for safety reasons, leaving them cut off from their families.

Rather than try to install phones or a network in a dangerous mine, Motorola and Dentsu used the one device the miners already had: the walkie-talkie.

A custom module at the surface converts the miners' radio signals into two-way voice calls that reach ordinary 5G phones, so a miner in the dark can speak to a family member above ground.

The design is built on existing infrastructure, making it affordable and scalable, and it turned a simple radio standard into a lifeline.

Use the radios they already carry, not new towers

Safety rules ban phones underground, so a new network was never the answer; the existing radio was.

Reusing walkie-talkies kept the cost low and let the system scale without new equipment.

The two-way call let a miner connect with family, addressing isolation rather than just awareness.

It demonstrated Motorola's phones and technology by solving a real, human connectivity problem.

When the constraint is a missing network, do not build new towers. Repurpose the low-tech channel that already reaches your users, and the cheapest object they already own becomes the product.

Motorola Deep Connect received multiple shortlists at Cannes Lions 2024, including in Audio & Radio, Direct and Entertainment, and it became a model for providing connectivity by repurposing infrastructure that already reaches the user.
