Ask HN: If WiFi had a smell, what would it be?

I'm currently working on a project that senses wifi and emits a scent to notify you of it's presence. In all your very professional opinions, what do you think wifi should smell like? My current thought is a combination of Ozone and Oranges. My hope is that the scent will eventually be used in public places to signify wifi for public use, where you can smell it - you can use it.
