The French Navy used wireless. The reader should note that this article is based largely on British knowledge of French equipment and practice.
1909[1]
Prior to 1909, the French had a haphazard use of wireless, signaling "en clair", or in plain text. Two French ships moving from Brest to Toulon communicated on a 1,000 foot wave and more feebly on a 1,200 foot wave. Their chatter seemed to indicate surprise and satisfaction with the results. Five character code groups called "Chiffre Z" were observed to be used in 1909 from the Eiffel Tower and by French ships. The protocol employed a "very long preamble."
In April, a large number of new French shore stations came online.
Procedural Signs
