In a world of MicroCells, FemtoCells, PicoCells, and overall NotAddressingTheRealProblemCells, we designed the BentoCell. It's a cell tower the size of a lunch box that draws less power than a lightbulb. They can be deployed by anyone with the push of a button -- no radio engineers necessary on the ground. They use a decentralized mesh network on the backend to allow for ease of setup and they self calibrate and self configure to ensure optimal network performance with little to no human oversight. They can tap into existing networks to extend coverage, or connect to any form of satellite Internet to provide coverage anywhere in the world, completely off the grid (with a solar panel, that is).
