What does wireless mean?
Wireless is chiefly an adjective meaning that something communicates or operates without connecting wires. It is most familiar in references to wireless networks, routers, phones, headphones, and other devices, although “cordless” is often more precise when the contrast is specifically with a wired telephone. As a noun, wireless can mean a radio set, radio communication, or historically radio telegraphy. The verb “to wireless” occurs in formal or historical writing but is uncommon today. Wireless technology became a familiar part of everyday life with radio broadcasting and later mobile communication, so the word carries associations with mobility, convenience, and rapid information exchange. Its historical development from electrical signaling to radio, mobile networks, and modern connected devices makes it a useful example of how a literal description becomes the name of a major technology.
Denoting communication, transmission, or an operation that takes place without connecting wires, especially by radio.
"The conference room has wireless internet access."
Common in both British and American English. In some contexts, “cordless” is more specific to a device that normally uses a physical cord.
A radio communication system, radio set, or device capable of wireless communication; historically, radio telegraphy.
"They heard the emergency broadcast on a small wireless in the kitchen."
The countable sense “a wireless” for a radio set is especially associated with British English and is now somewhat old-fashioned in many contexts.
To communicate or transmit a message by radio or another wireless system.
"The operator wirelessed the message to the mainland station."
Uncommon today and most natural in formal, historical, or technical writing.
This plural is used for countable wireless sets or devices but is uncommon in modern usage; wireless communication itself is normally uncountable.
"The museum has restored several wirelesses from the early twentieth century."
Long before smartphones and Wi-Fi, “wireless” was a serious term for radio telegraphy: sending coded messages through the air.

Where does wireless come from?
Wireless was formed in English from wire and the suffix -less, literally “without wire.” The term was applied to telegraphy in the early nineteenth century and later came to denote communication through radio waves rather than along a physical cable. Wire itself descends from Old English wīr, and related modern forms such as wired, wiring, and wiry continue that word family.
How wireless is actually used
The adjective is now common in general English. As a countable noun meaning a radio set, “a wireless” is especially traditional in British English. The verb “to wireless” is uncommon and sounds formal, dated, or technical.
