'wirelessly-operated' originates from the combination of 'wireless' and 'operate', where 'wireless' meant 'without wires' and 'operate' meant 'to control or manage'.

'wireless' changed from the early 20th-century term 'wireless telegraphy' and eventually became the modern term 'wireless', while 'operate' has remained largely unchanged.

Initially, 'wireless' referred to radio communication, but over time it evolved to include any technology without wires, and 'operate' has consistently meant 'to control or manage'.
