Wi-Fi Hot Spot 2.0 (HS 2.0)
Hotspot 2.0, also known as HS2 and Wi-Fi Certified Passpoint, is a new standard for public-access Wi-Fi that enables seamless roaming among WiFi networks and between WiFi and cellular networks. HS 2.0 was developed by the Wi-Fi Alliance and the Wireless Broadband Association to enable seamless hand-off of traffic without requiring additional user sign-on and authentication.
The idea is for mobile devices to automatically join a Wi-Fi subscriber service whenever the user enters a Hotspot 2.0 area, in order to provide better bandwidth and services-on-demand to end-users, while also alleviating mobile carrier infrastructure of traffic overheads.
A hot spot (or hotspot) is a wireless LAN (local area network) node that provides Internet connection and virtual private network (VPN) access from a given location for users of devices with wireless connectivity. Normally, a user must connect manually to a hotspot by checking the wireless connection options, selecting one, and entering authentication information, usually a simple password. The physical connectivity zone is determined by the range of the wireless router(s) owned by the establishment. In most cases the radius is about 100 to 200 meters.
Hotspot 2.0 is based on the IEEE 802.11u standard, which is a set of protocols published in 2011 to enable cellular-like roaming. If the device supports 802.11u and is subscribed to a Hotspot 2.0 service it will automatically connect and roam.
Network discovery, registration, provisioning, and access processes are automated, so that the user does not have to go through them manually in order to connect and stay connected.
