Responsible for eventually giving us the television, mobile phone, radio, radar, satellite navigation and even wireless internet access, Nikola Tesla’s work in 1891 creating a wireless communications network was surely one of the most inventive spells of his career. Since Tesla’s network, wireless communications have gone from strength to strength, as the following devices show…
Sir Oliver Lodge sent the first transmission signal in 1894 — a year before Marconi, who was later awarded the wireless telegraph patent.
Scottish inventor John Logie Baird demonstrates the world’s first moving image on his ‘televisor’ device — a mechanical precursor to the TV.
The first handheld mobile phone is demonstrated by two employees at Motorola. It weighs in at a rather hefty one kilogram (2.2 pounds).
While wireless internet existed in academic facilities, it wasn’t until 1997 that standards were laid down for its widespread adoption.
