5G Is Real Verizon Wireless has won the race to 5G—sort of.

But what were the phones that made it happen; who were the pioneering brands that made today's handsets possible; and which phone, out of the thousands launched since the 1980s, was the most important? Answer: quite a few. But first: a history lesson.  The world’s first mobile phone call was made on April 3, 1973, when Martin Cooper, a senior engineer at Motorola, called a rival telecommunications company and informed them he was speaking via a mobile phone. The phone Cooper used, if you cou...

No single one is completely foolproof, but if you consider the following tips, you stand a better chance of ensuring your ignition key doesn't get lonely. From the April 2005 issue Just because no one has ever stolen your motorcycle before, that doesn't mean that it won't happen today. All kinds of motorcycles get stolen from all sorts of places. Though popular bikes, especially those that are frequently crashed or have expensiove crash-susceptible parts are the most common targets, even boring little beaters can get snatched. We have heard of old beat-up "entry-level" being stolen despite being carefully locked up and covered as well brand new bikes wearing locks and stashed away in seemingly safe locked private garages inside gated yards. Motorcycle gathering places—shows, races, rallies, charity ride, etc.— are often targeted. Urban areas are probably more danger...
