Definition: wireless
Transmission through the air. Although all forms of radio transmission over the air (AM, FM, TV, cordless phones, cellphones, etc.) are naturally wireless, there is a tendency for the term to refer only to Wi-Fi or to cellular data services. For example, a cellular provider may call its extra-cost data service wireless, although its voice service is obviously wireless as well.
