Hotspot 2.0, Next Generation Hotspot (NGH), etc.


From ZDNET:


Hotspot 2.0 is about certifying the hotspot itself, providing authentication using SIMs or certificates and the 802.11i standard, and using the recent 802.11u standard to provide performance and other information about the hotspots visible to a device. This will allow you to roam onto a hotspot with good connectivity that you have the right account to use, doing away with the need to select the network or enter your details into a web page, as you do today.

The Wi-Fi Alliance deals with the Wi-Fi hardware and the authentication specification under the name Passpoint, but this certification doesn't cover everything. The Wireless Broadband Alliance is a group of mobile and Wi-Fi operators that takes the Passpoint certification and ensures interoperability with other parts of the network — including authenticating to carriers' remote access RADIUS (Remote Authentication Dial-In User Service) servers, as well as roaming and billing.

"Next Generation Hotspot is the implementation of Hotspot 2.0 into a real, live network", explains Nigel Bird, the NGH Standardisation Manager at Orange Group.

From Next Generation Hotspot whitepaper:


A new program called Next Generation Hotspot (NGH) - using the latest HotSpot 2.0 specification1 - allows a mobile subscriber to connect automatically and securely to Hotspots using his service provider credentials while maintaining roaming visibility for the operator. NGH enables operators to continuously monitor and manage “cellular-like” service over Wi-Fi domestically and internationally so as to enhance performance and meet the demand for mobile data services over heterogeneous RANs - cellular and Wi-Fi. This enables mobile operators to simultaneously optimize backhaul throughput, offload specific traffic rapidly (e.g. video) and achieve better economics than traditional, cellular-only solutions.

The Wireless Broadband Appliance (WBA) and Small Cells Forum recently announced collaboration on this topic, see here.

Dr. Abbas' presentation is incorrect re need to replace installed base of WiFi APs to support Hotspot2.0. A SW upgrade is all that's needed. Also his treatment of WiFi interference is misleading... unplanned small cells in licensed spectrum look a lot like WiFi in unlicensed spectrum and WiFi is fundamentally designed for that. SON will take a long time to get right and a scheduled MAC is fundamentally inferior in LAN environments. WiFi is ahead of cellular by more than 5 years... WiFi had OFDM before cellular... WiFi had MIMO before cellular etc.
