Appealing
If this made having a stable and reliable hotspot while traveling easier and more affordable, especially abroad, I'd be thrilled to sign up.

Re: Progress is good...
But ANDSF solves the authentication problem within operators' own WiFi footprints, doesn't it?

Re: Progress is good...
Sarah.  That's actually a misunderstanding.  Hotspot 2.0 is the standard for securely authenticating users onto a carrier-grade Wi-Fi network.  ANDSF is the standard for network-based policy decisions about whether the user will move onto the cellular or the Wi-Fi network given network conditions.  They are not mutually exclusive.  They work in synch.

HS2.0 Seamless Connectivity
HotSpot 2.0 does provide seamless and secure connectivity.  The MWC public Wi-Fi provided both HS2.0 and PSK (Pre-Shared Key - e.g. SSID with password) public access.  This was for two key reasons... First, there needed to be legacy support for non Passpoint compliant devices (Passpoint is the certification the WFA does to ensure HS2.0 device compliance).  Second, HS2.0 authentication goes back to your home operator for authentication, so the home operator of your SIM must be participating in the roaming agreement.  If your home operator wasn't participating you would need to use PSK. 

So, given a Passpoint device and the right operator SIM, why would the MWC experience seem not so seamless?  This is due to the connection priority in your phone.  Most phones will prioritize a known network over an unknown network.  A known network is one that you have connected to before.  HS2.0 networks are considered unknown as they authenticate when discovered, so don't have to be remembered by the device.  The most common known networks on your phone would be your home and/or office. So what happens if your home or office is next to a coffee shop that supports HS2.0?  If HS2.0 was the prioritized connection, then you would connect to the coffee shop instead of your home/office - which is not the desired behavior.

Back to MWC... in order for HS2.0 to work seamlessly your device must have no known networks available, e.g. in Wi-Fi range.  So if you had already connected to MWC via PSK, it would always connect this way.  If you tell your device to forget the PSK network, then bingo... right into HS2.0.  You would not have to tell your device to forget all known networks.  For example, your home network or office network could still be on the device, but since those networks were not available at MWC, no problem, HS2.0 would find and connect you automatically. 

Here is the good news!  As more and more networks enable HS2.0 the more seamless your experience will be.  No more selecting an SSID, accepting a contract, signing up for service, or punching in a credit card.  The connection is done automatically through a roaming relationship with your home operator - just like cellular.  Second, HS2.0 is secure!  It uses 802.1x for L2 authentication, 802.11i for L2 air encryption, and EAP methods (EAP/SIM for MWC) for L3 authentication.  This is far more secure than existing WebAuth and WISPr deployments.

So, although the technology described above may be too complex for the average user, they won't care because they'll just connect automatically, seamlessly and securely.  And... isn't that how it ought to work?

Re: Progress is good...
I guess Vodafone's Always Best Connected is what they are trying to achieve, but there will always be conflict of interest, since "best connected", more often than not, means lowest cost to subscriber.

Re: Progress is good...
I'll have to find the stats for the exact number, but most WiFi usage still happens in the home and office. That's not to say that public WiFi quality doesn't matter. It does, of course. If H2 can help NOT put you on broken or overloaded networks, that'd be just as valuable as getting you on the good ones, IMO.
