Well, you might be able to tell the type, based on the MAC address. After all, if you're seeing it, at all, it must be sending out Broadcast packets, so those should have a MAC address in them, which you can compare to the lists and find vendors for, etc.
As for name, unless it's broadcasting it's name (which some do, some don't,) you won't likely find a name, without a client authenticating to it.
