Community WiFi is a network made of many distributed access points (home routers and public hotspots) that dedicate part of their capacity to an open network, so anyone nearby can connect.
Instead of building a new network from scratch, it uses infrastructure that already exists: the routers internet service providers (ISPs) install in homes, and access points in parks, shops and public spaces.
How it works
- Two networks on one router. The home device broadcasts its usual private network plus a second, public network (known as a homespot).
- Fully separated. Both networks are isolated with VLANs and public traffic travels through secure tunnels to the network core, so public users cannot see the home’s traffic or devices.
- Only uses what’s spare. The public network runs on the spare capacity of the router and the fiber or cable link; the household’s contracted bandwidth is untouched.
- An access portal. When connecting, users go through a captive portal where they sign up, use free minutes or buy a data package.
- A central gateway. A WAG (Wireless Access Gateway) aggregates traffic from thousands of access points, authenticates users and enforces network policies.
Why it matters in Latin America
Internet access is increasingly seen as a basic utility, on par with water and electricity. But bringing broadband to everyone, everywhere, is expensive. Community WiFi multiplies coverage using networks that are already deployed, even on routers that are not the latest generation.
What each party gains
- People: connectivity away from home on any device with WiFi and a browser, no app needed.
- ISPs: a new revenue stream on the network they already own (see how).
- Municipalities and businesses: their connectivity stops being an island and joins a much larger integrated network.
Community WiFi with Streetwifi
Streetwifi currently runs a network of more than 25,000 access points in Paraguay and Argentina. Anyone can connect for 15 or more free minutes a day and buy data packages if they need more. Average speed ranges from 20 to 50 Mbps, depending on proximity to the access point.
