current wireless systems like 3G fit every well in this picture but only as one constituent part. Present systems cannot by themselves offer enough network capacity link capabilities and coverage for supporting a vision of highly connected world fully exploiting broadband communications. Moreover the bandwidth required for that purpose is far beyond the figures in use today and hence a new spectrum allocation is necessary .the vision of highly connected world where virtually every entry can communicate to each other in any possible situation anytime exploiting broadband capabilities is truly appealing and equally important fits every well in the aforementioned logical chain

visions and foresights about 4G

here lets us first discuss about the vision on ITU(International Telecommunication Union) of future wireless communication systems considers as our base line, finally in an attempt to foresee 4G,we present our own views ,in addition to the user trends previously discussed ,other important developments and trends could help us to better approach ,define and justify future 4G networks ,trends in various categories support the argument of an explosive increase in the demand of band width required to realize a truly wireless knowledge society.. will cont..
