Cell phone covers – Custom iPhone Cases
In 1908, U.S. Patent 887,357 for a wireless telephone was issued in to Nathan B. Stubblefield of Murray, Kentucky. He applied this patent to “cave radio” phones and not without delay to cellular telephony as the term is presently accepted. Cells for mobile phone base stations were invented in 1947 by Bell Laboratories engineers at AT&T and further developed by Bell Labs during the 1960s. Radiophones have a long and sundry history going back to Reginald Fessenden’s invention and shore-to-ship demonstration of radio telephony, through the Second World War with military use of radio telephony links and civil services in the 1950s, while handheld cellular radio devices have been available since 1973. A patent for the first wireless phone as we know today was issued in US Patent Number 3,449,750 to George Sweigert of Euclid, Ohio on June 10, 1969.

Martin Cooper, a Motorola analyst and executive is widely considered to be the inventor of the first practical mobile phone for hand-held use in a non-vehicle setting. Cooper is the inventor named on “Radio telephone system” filed on October seventeen, 1973 with the US Patent Office and later issued as US Patent 3,906,166. Using a modern, if somewhat heavy cartable handset, Cooper made the first call on a hand-held mobile phone on Apr 3rd, 1973 to a rival, Dr. Joel S. Engel of Bell Labs.
In 1983, Motorola DynaTAC was the first approved mobile phone by FCC in the U. S. In 1984, Bell Laboratories developed modern commercial cellular technology ( based, to a big extent, on the Gladden, Parelman Patent), which employed multiple, centrally controlled base stations ( cell sites ), each providing service to a tiny area (a cell). The cell sites would be set up such that cells partly overlapped. In a cellular system, a signal between a base station ( cell site ) and a terminal (phone) only need be tough enough to reach between the two, so the same channel can be employed concurrently for separate conversations in different cells.
Until the early 1990s, following arrival of the Motorola MicroTAC, most mobile phones were too enormous to be carried in a jacket pocket, so they were often installed in automobiles as car phones. With the miniaturization of digital components and the development of more complicated batteries, mobile phones have become smaller and lighter.
