| 簡介： | In an age where near-instantaneous communication is available through all manners of portable and pocket-sized devices, it is easy to overlook the genesis of telecommunication instrumentation—the telephone.

This detailed volume examines the development of the telephone and related technologies, including everything from the transistor to fax machines, smart phones, and VoIP technology. |
