Smart thermostat
Another major feature of smart thermostats is their ability to connect to the internet. Smart thermostats are designed with a WiFi module that allows the thermostat to connect to the users home or office network and interface with a web portal or smartphone application, allowing users to control the unit remotely. The WiFi feature also has the ability to send reports on energy usage and HVAC system performance via the web portal, informing the user on their energy efficiency and how it compares to other smart thermostat users. It also alerts users when a problem arises with their HVAC system or when it is time for equipment maintenance. The thermostat also uses the WiFi connection to display current weather conditions and the weather forecast.
Free (ISP)
Free deployed the IPv6 infrastructure in only 5 weeks, from 7 November to 11 December 2007, thanks to an innovative 6rd (IPv6 rapid deployment) proposal by Rémi Després.In May 2009 Free reconfigured the set-top boxes to act as Wifi hotspots by default. With over 3 million hotspots, it is thought to be the largest Wifi hotspot network in the world during that time. They require authentication which makes them only accessible to Free's ADSL and now mobile customers. Their main use is thus to let customers away from home continue accessing the Internet using the ADSL connection of other Free customer within Wifi range. For security reasons this access is isolated from the ADSL user's normal Wifi network, and is given lower priority.In 2003, Free introduced unlimited phone calls at no additional price, while other phone operators or ISPs charged per-minute fees for telephone calls. Competitors have then been forced to imitate these changes, but with fewer destinations included or at an additional price. Bundled Free subscribers enjoy same free calls as those unbundled since March 2004. Calls to United States and Canada have been free of charge since December 2005.
