Overview

Start as a small neighbourhood provider with one rented office and a handful of technicians. Every link needs real line of sight, every install needs a technician to drive there with the right gear, and every overloaded sector costs you customers. Grow it into a city-wide network.

Real wireless network planning

Towers, sector antennas, point-to-point backhaul and customer equipment. Height, antenna aim and line of sight all matter.

A physical 3D world

Buildings and mountain ranges block signal. Route links around ridges or put relays on the peaks.

Technicians on the road

Your crew drives the city's road network to build towers, install customers and repair outages, restocking at your offices along the way.

Run the business

Set plan pricing, hire staff, rent offices, run marketing campaigns and keep an eye on your profit and loss before the money runs out.
