IP Network To Replace Circuit-Switch, Boost Data Rates In Handhelds The mobile phone has evolved to do much more than place a call. Common desktop applications such as e-mail access, Web browsing, and downloading music and videos are becoming common on handsets. Uploading clips to YouTube along with direct video sharing merely hint at what is to come. To do so, though, they need higher bandwidths with equally high reliability and handsets that can process such compute-intensive applications... — Jay Srage , et al. August 6, 2007 National Association of Broadcasters Engineering Handbook - 10th Edition This not-so-little jewel has 2072 pages and weighs 11 lbs. (yes, I actually weighed it).
