Wireless is an old-fashioned term for a radio transceiver (a mixed receiver and transmitter device), referring to its use in wireless telegraphy early on; now the term is used to describe modern wireless connections such as in cellular networks and wireless broadband Internet.

History

Main article: Radio: Invention and history

Originally, radio technology was called 'wireless telegraphy', which was shortened to 'wireless'. The identity of the original inventor of radio, at the time called wireless telegraphy, is contentious. The controversy over who invented the radio, with the benefit of hindsight, can be summed up with the answer to who invented 'wireless transmission of data'? Nikola Tesla holds the US patent for this. The founding principles and inventions of wireless technology can be found in the lectures and patent record of the electrical engineer Tesla (and in his 1916 deposition on the history of wireless and radio technology). It was also later pioneered by Jagdish Chandra Bose and Guglielmo Marconi. A wireless set was the radio receiver, referring to its use as a wireless telecommunication station. The term "wireless" was widely used in the UK and Ireland, long after radio was being used for other signals, such as music.

Three DEMO Companies To Keep An Eye On
Jason Kincaid Mon, 08 Sep 2008 11:00:11 -0000
This week we're going to see dozens of companies launch new products. Here are a few of the companies presenting this week at DEMO that are showing some strong potential: In most cases, choice is a good thing. But when it comes to online video, the abundance of content available on the web can be overwhelming. ffwd (pronounced fast-foward) deals with this by picking your videos for you. The site uses video meta data as well as user behaviors to create virtual "channels" of video, which are essentially dynamically updated playlists. Rudder shares a lot in common with Mint, a personal finance site that debuted last year at TechCrunch40 (and won the conference's top prize). Both sites present financial data in attractive, intuitive graphs. But Rudder is taking a slightly different approach: while Mint analyzes your past spending habits to help you adjust in the future, Rudder is concerned with telling you how much you have available to spend on a given day. Photrade With image piracy rampant on the web these days, a number of startups have sprung up to help users easily obtain legal pictures. Photrade has a similar goal, but it also manages to help casual photographers make some cash in the process.

RealNetworks Lets You Copy DVDs to Your Hard Drive — And Keep the DRM
Don Reisinger Mon, 08 Sep 2008 07:00:37 -0000
As anyone with a lick of tech knowledge knows, ripping a DVD onto your hard drive is, well, frowned upon by the "Powers that be" in the motion picture industry. Realizing that, RealNetworks has launched a new solution called RealDVD, which lets users copy DVDs onto their hard drives without facing legal troubles. Even better, it only takes about 20 minutes to do so. Sounds great, right? There's only one catch: it keeps the DRM. After copying the DVD onto your hard drive, you can't transfer the movie to a friend's computer, so you'll be stuck using your own. Much like iTunes, though, RealDVD lets you authorize five computers to play the movies on the hard drive.
