Motorola Slvr. The Motorola Slvr (styled SLVR) is a former series of candybar mobile phones from Motorola, and was one of the series in the 4LTR line. The first phones were released in early 2005. Inspired by the Razr, they were designed to be very thin and lightweight.
Although a relatively large backpack-carried radio rather than a handheld model, the SCR-300 was described in War Department Technical Manual TM-11-242 as "primarily intended as a walkie-talkie for foot combat troops", and so the term "walkie-talkie" first came into use. The final acceptance tests took place at Fort Knox, Kentucky in Spring ...

Wireless network technologies. Mobile radio telephone systems were mobile telephony systems that preceded modern cellular network technology. Since they were the predecessors of the first generation of cellular telephones, these systems are sometimes retroactively referred to as pre-cellular (or sometimes zero generation, that is, 0G) systems.
The antennas contained in mobile phones, including smartphones, emit radiofrequency (RF) radiation ( non-ionizing "radio waves" such as microwaves ); the parts of the head or body nearest to the antenna can absorb this energy and convert it to heat. Since at least the 1990s, scientists have researched whether the now-ubiquitous radiation ...
