In May–June 1899 the Spanish Army sent Cervera to visit Marconi's radiotelegraphic installations on the English Channel to study the Marconi system with the goal of adapting it for the Spanish Military. He began collaborating with
Guglielmo Marconi on resolving the engineering problems of a long range wireless communication, obtaining some
patents by the end of 1899. On 22 March 1902 Cervera founded the Spanish Wireless Telegraph and Telephone Corporation. Cervera brought to the Spanish Wireless Telegraph and Telephone Corporation the patents he had obtained in Spain, Belgium, Germany and England. He established the second and third regular radiotelegraph service in the history of the world in 1901 and 1902 by maintaining regular transmissions between
Tarifa and
Ceuta for three consecutive months, and between
Xàbia (
Cap de la Nau) and
Ibiza (
Cap Pelat). This was after Marconi established the radiotelegraphic service between the
Isle of Wight and
Bournemouth in 1898. According to the latest research conducted, Julio Cervera developed the radio eleven years before Marconi. It is true that the Italian invented wireless telegraphy before Cervera, but for transmitting signals, not sound. Cervera transmitted the human voice—and not signals—wirelessly between
Jávea and
Ibiza in 1902, which meant connecting two distant points nearly 85
kilometers. However, fifteen years before Marconi and four years before Julio Cervera,
Nikola Tesla had already made several demonstrations and publications of the principles of radio. Following Marconi's patent usurpation, Nikola Tesla took Marconi to court, winning the lawsuit before the U.S. Supreme Court and remaining as the authentic inventor of the radio. Cervera thus achieved some success in this field, but his radiotelegraphic activities ceased suddenly, the reasons for which are unclear to this day. ==Other activities==
