1885 – Thomas Edison patented a system of wireless communication by electrostatic induction . 1886 – Heaviside introduced impedance as the ratio of voltage over current. Hertz started his work to demonstrate the existence of radio waves and published his results in 1888.22 Tem 2015

Read moreWhat is the max distance of 4G?
Over 4g, the maximum distance is only 400 meters according to my own stimation. In this case I am talking bout a crowded city as buenos aires. The theoretical maximum range without Extended Cell Capability (which is not used inland, as far as I know), is 35.7km, because of signal delay vs. synchronisation timeframe.26 May 2011
Read moreWhat is the maximum range of a cell phone?
A typical cellphone has enough power to reach a cell tower up to 45 miles away . Depending on the technology of the cellphone network, the maximum distance may be as low as 22 miles because the signal otherwise takes too long for the highly accurate timing of the cellphone protocol to work reliably.
