Question

"which type of network connects smart devices or consumer electronics within a range of about 30 feet (10 meters) and without the use of wires or cables?"

Answer 1

The answer is PAN (Personal Area Network)

With the simple reference to Personal, this kind of network serves one individual rather than several users. It is an interconnection of IT devices within a range of an individual person. It could be used to sync data from a portable device like a PDA to a PC or a desktop computer or transfer data wirelessly to a printer.
