Telegraphy
In 1889 Preece assembled a group of men at Coniston Water in the Lake District in Cumberland and succeeded in transmitting and receiving Morse radio signals over a distance of about 1 mile (1.6 km) across water.
Preece also developed a wireless telegraphy and telephony system in 1892. Preece developed a telephone system and implemented it in England. A similar telephone system was patented in the United States by Alexander Graham Bell in 1876. In 1885, Preece and Arthur West Heaviside (Oliver Heaviside's brother) experimented with parallel telegraph lines and an unwired telephone receiver, discovering radio induction (later identified with the effects of crosstalk).
