iOS WiFi Sharing

785 views

To me this is equal parts magic and sorcery. At my house, someone with an iPhone tries to connect to my WiFi. I get a pop up on my own iPhone and can share my WiFi password with them automatically and they connect to my network.

Your phone is just as much a computer as a desktop PC or server on the cloud. It has wifi capability, which is a part of peer-to-peer networking. Peer-to-peer means exactly that: neither is in charge, neither has capabilities the other lacks.

After that, it’s just a matter of software – what features does the manufacturer WANT you to have? That’s the magic part – convincing a big company to let you cut ties with a server-based infrastructure and do your own serving and sharing without one of their apps. We’re long since past the point where we even need phone companies for in-city calls – the radios and cpus on modern cellphones are easily capable of doing the job without a central service of any kind, and there’s plenty enough of them to cover in-city ranges.

Your phone knows the wifi key, theirs doesn’t. But you exist as a contact in their phone, so it uses the same technology as airdrop to contact your phone and present the question to you about sharing the pass code.
