This is in regard with the new technology called passpoint.

The technology is explained as an authentication-free and SSID-free from the user's perspective, how would it recognize the passpoint enabled client and get it connected to the wifi ??? Would the access point infrastructure be merged with the cellular companies ??

How does the technical backend flow ?

Here's a (oops..leaked) presentation that covers the topic pretty well. If you google "+ruckus hotspot 2.0" you'll find some others as well.

Hello Mayur,

As Passpoint-enabled hotspots proliferate, users will discover another exciting benefit: Wi-Fi roaming. Service providers are working together to define mechanisms for subscribers to “roam” to one another’s hotspots – meaning that you’ll be able to connect using Wi-Fi in more locations than ever.

Please refer to the following link,

Also For Samsung Galaxy S3 and S4 phones, when they interact with our ZD, the MNC info in the 3GPP Cellular Network information should in some cases omit the leading zero, or else the phone will not automatically connect through Passpoint.

The IMSI is a string of digits without any explicit structure, so the peer may not be able to determine the length of the MNC portion. If the peer is not able to determine whether the MNC is two or three digits long, the peer MAY use a 3-digit MNC. If the correct length of the MNC is two, then the MNC used in the realm name includes the
first digit of the MSIN. Hence, when configuring AAA networks for operators that have 2-digit MNCs, the network SHOULD also be prepared for realm names with incorrect, 3-digit MNCs.

Please take a look at the following RFC around, Extensible Authentication Protocol Method for Global System for Mobile Communications (GSM) Subscriber Identity Modules (EAP-SIM)

I hope this would help answer most of your doubts.
