I just realized that new cellular network technologies seem to be launched every 8-10 years. Analog cellular networks such as the C-Netz started operation back in 1984, GSM went on air in 1992 and UMTS became operational in 2002. Now it’s 2008 and LTE and mobile WiMAX are at the doorstep. While WiMAX is a bit ahead and will be used by newcomers, most incumbent operators will probably opt for LTE which in my opinion won’t go live before 2010, i.e. 8 years after UMTS was generally available. And from there it will take another year or two before we see LTE devices beyond PC cards and a network coverage beyond a few major cities.
