Île Sans Fil (French:"wireless island") is a non-profit community wireless network that provides free public wireless Internet access to mobile users in public spaces throughout the island of Montreal, Quebec, Canada. The organization works with cafés, restaurants, bars, stores, community organizations, and individuals to provide free Internet access in public spaces. As of April 2010, the network had over 140,000 registered users (1,000+ users daily) and over 212 live hotspots. In 2016, the organization changed it operating name to Zone Access Public Montréal Île Sans Fil's mission is to use technology to bring people together and foster a sense of community. In pursuit of that goal, Île Sans Fil experimented in using hotspots to promote interaction between users, display new media art, and provide geographically and community-relevant information. The group was volunteer-based until 2010. In addition to the deployment of these hotspots, a group of developers inside Île Sans Fil lead the development of the captive portal suite WiFiDog. This open source software was originally conceived for Île Sans Fil's internal use, but gained international recognition. More than 30 community wireless networks outside Montreal used the WifiDog solution: New York, London, Berlin, Vancouver, Toronto, Quebec City, Sherbrooke, Paris, Brest and Marseille. Technical projects WiFiDog The WiFiDog project is an open source, embeddable captive portal solution. It uses the physical limitations of wi-fi as an advantage to encourage hyper-local social interactions through location-based content and location-based services. Some of the content shown to users is in the form of location-specific images via Flickr. Users can send pictures to the portal pages of specific ISF hotspots by using the appropriate tag; WiFiDog will grab them via Flickr's API and present them on the portal page to subsequent users. Another source of dynamic, interactive locative content is the use of any RSS feeds, from either the owner or other local sources. The WiFiDog project was started by Île Sans Fil and has been used by over 30 communities and businesses across four continents. It can also aggregate and present other content in addition to that from Flickr and RSS. HAL HAL is a new open source platform to distribute audio and video content to wi-fi network users. HAL assists Montrealers in discovering local artists and media producers by making their works available via wireless jukeboxes located at select Île Sans Fil hotspots. HAL provides high-speed streaming of video and audio together with location-relevant
