Microsoft, about an year ago, announced about the upcoming Hotspot 2.0 support to Windows 10 Mobile. On 17 April 2016, Microsoft confirmed that Windows 10 Mobile Redstone will get Hotspot 2.0 Soon. It also confirmed that this feature will be arriving to Insiders in the upcoming weeks.
The advantage of Hotspot 2.0 is that it allows you to seamlessly move from one hotspot to another on a network, without having to authenticate separately for each one. The feature is also called as HS2 and Wi-Fi Certified Passpoint. It is an approach to public access Wi-Fi by the Wi-Fi Alliance. It allows mobile devices to join a Wi-Fi subscriber service automatically as soon as the user enters a Hotspot 2.0 area. This offers better bandwidth and services-on-demand to end-users. It prevents mobile carrier infrastructure of traffic overheads. Hotspot 2.0 is based on the IEEE 802.11u standard. IEEE802.11u 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.
Now when Microsoft releases Windows 10 Mobile Redstone, you need to enable Hotspot 2.0 and then you will be able to see available Hotspot 2.0 networks listed in the Wi-Fi networks list. As Microsoft mentioned that the feature will be arriving to Insiders soon but for public, Windows 10 Mobile Redstone will get Hotspot 2.0 with the Anniversary
