Getting list of connected devices and types to a network without connecting

I’m using kismet to get a list of networks nearby and all the devices that are connected to them.

I can get the MAC address off these devices, but I was wondering if it was also possible to get the type of device as well, for instance iPhone 5 (or even more detailed, like iPhone 5 Black). I would not have the credentials to the network.

Alternatively, if I turn my computer in a router, can I determine all devices and types that are in close proximity?

I’m basically wondering if there is a way you can determine all devices that are close.

Not sure of an automated way to do this but you can look up MAC addresses to get some information on the device (at least the manufacturer) — http://www.macvendorlookup.com/
