My Larousse says
radioélectrique (adj): radio.

Here's my translation:
The inherent risks of radio keyboards
All radio radiation risks being intercepted and, with appropriate
processing, revealing the sense of the signal it carries. SCSSI
scheming experience has shown that this risk exists especially for
systems where a micro-computer and its keyboard communicate by
radio.
It has been observed that any metallic conductors found near the
emitting keyboard (??? [I don't know what "fils du secteur" are],
Ethernet cable, telephone cable) can carry and propagate the
signal to a greater effective distance than that of the direct
emission from the keyboard. Redisplayed on a "spy" microcomputer,
everything typed on the radio keyboard then appears in the clear,
even passwords whose characters are masked on the original screen.
