The story

Founded by Martín Varsavsky in 2005, in Madrid.1

Early years

Originally, the company intended to create a network for Wi-Fi access wherever customers went. To become a Fon member, users had to buy a special router called “Fonera”. With this router, they agreed to share a part of their bandwidth as a second Wi-Fi signal, in exchange for the right to use other Fon members' hotspots. To achieve this, Fon operated a system of dual access wireless networks. In 2007, Fon's development model shifted to encompass ISPs, and it began to work on creating Wi-Fi community networks with British Telecom (BT) and SFR. In November 2007, Fon deployed its first Wi-Fi rollout and continued using this foundation with more telco partners in the years to come.

2016

In 2016 the company evolved to also include premium networks such as airports, hotels, convention centers, public spaces. Fon also has a technology to allow providers to deliver services to their own customers.

Subsidiaries and Investors

Hardware and firmware

Fon initially operated with a software that could be downloaded for compatible routers, mainly Linksys routers. The firmware for this service was based on OpenWrt. The firmware had been customized specifically for use in the Fon Community, allowing consumers to share their broadband connection and to connect to other Fon Spots around the world.

Fon firmware creates two different Wi-Fi signals: one private and one public.

Private ('MYPLACE'): encrypted and intended for the owner's private use. Only the Fon Spot owner can access the internal network, computers and files.

Public ('FON_FREE_INTERNET'): un-encrypted or open, but username and password protected so allowing only registered Fon users to access the Fon Wi-Fi community network, but they cannot access the consumer's private network.

The new 2014 Fonera SIMPL, introduced in February 2014, includes Facebook integration. The owner of the Fonera SIMPL may register their own Facebook account with the device. Once this is done, any user that is a 'Facebook Friend' of the owner is granted access to that Fonera (only).

The 'Fonera Business' takes Facebook integration further by offering free WiFi to customers of a business who are asked to 'Like' the Facebook page for the business in order to gain free WiFi access.

In early 2018, Fon's online shop was closed.
