But how does one broadcast a description for a Wi-Fi network?I suspect that is a description of the wifi network.
Likely some commercial ones, especially some specialty ones for airlines and the like, have certain options that are available to them in relation to that and probably some other things.But how does one broadcast a description for a Wi-Fi network?
This may have something to do with Hotspot 2.0.
Good call! Seems like everything lines up with Hotspot 2.0 re: supplemental fields that can be sent and displayed on the client side. Boingo has been rolling that out since 2013/2014, iOS supports since v7.
And to tie back to a different post, does appear to be different commercial grade equipment that is configured for this task vs. the generic home router.
Hotspot 2.0, also known as HS2 and Wi-Fi Certified Passpoint,[14] is an approach to public access Wi-Fi by the Wi-Fi Alliance. 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 and relieve carrier infrastructure of some traffic.
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.
Thank you so much! Mystery solved
