The wireless revolution began in the 1990s, [12] [13] [14] with the advent of digital wireless networks leading to a social revolution, and a paradigm shift from wired to wireless technology, [15] including the proliferation of commercial wireless technologies such as cell phones, mobile telephony, pagers, wireless computer networks, [12 ...
The Wardenclyffe Power Plant prototype, intended by Nikola Tesla to be a "World Wireless" telecommunications facility.. The World Wireless System was a turn of the 20th century proposed telecommunications and electrical power delivery system designed by inventor Nikola Tesla based on his theories of using Earth and its atmosphere as electrical conductors.
The technology of wireless power transmission can eliminate the use of the wires and batteries, thereby increasing the mobility, convenience, and safety of an electronic device for all users. [2] Wireless power transfer is useful to power electrical devices where interconnecting wires are inconvenient, hazardous, or are not possible.
That first cell phone began a fundamental technology and communications market shift to making phone calls to a person instead of to a place. [ 6 ] [ 19 ] Bell Labs had introduced the idea of cellular communications in 1947, but their first systems were limited to car phones which required roughly 30 pounds (12 kg) of equipment in the trunk.

Wardenclyffe Tower (1901–1917), also known as the Tesla Tower, was an early experimental wireless transmission station designed and built by Nikola Tesla on Long Island in 1901–1902, located in the village of Shoreham, New York.
Tord Wingren is a Swedish inventor, entrepreneur, and scientist and holder of 28 patents relating to wireless communication, technology, and the implications of light on the human body. [1] He developed Bluetooth technology while working with Ericsson Mobile Communications , and is the co-founder of several technology companies including ...
Before the discovery of electromagnetic waves and the development of radio communication, there were many wireless telegraph systems proposed and tested. [4] In April 1872 William Henry Ward received U.S. patent 126,356 for a wireless telegraphy system where he theorized that convection currents in the atmosphere could carry signals like a telegraph wire.
