Hi there 3G is the "new generation" in mobile phone technology. I have been working as a network designer for over 10 years in Australia on 2G networks [GSM], and am preparing to delve into 3G as we speak. 3G is still a digital network, like 2G, but has very different planning techniques - from a radio point of view. My main role has been designing and maintaining the 2G radio network, so I can answer questions about that. Tell us, what your interest is in 3G? Do you want to learn how it works (see http://www.umtsworld.com/) or visit Agilant, Ericsson or Nokia web sites for some "general" info about mobile networking.
