This chart explains - very broadly - why I say that WiMAX is already dead in his cot. Someone has compared the flop at that historic winning of the Sony Betamax against VHS, in the media a few decades ago.
more succinctly: WiMAX is that the Super 3G technologies evolve towards the standard of the fourth generation. Not be long now, but unfortunately the WIMAX had no time to spread their broadband wireless networks so "vaguely competitive." The trouble was this: the WIMAX had to build their own networks from scratch (and they know something LINKEM AIR in Italy!). The strength of LTE is that it is the smoothest transition for users of mobile phones to existing capacity downoad / upload similar (even better!) Compared to that of ADSL households. If you have 100 Mbits in download and mobile phone users 50 in the transmission LTE (4G) or any PC or tablet or Mobile smartphone can do well whatever he wants in on the net .. full mobility (including streaming video and emulation of the DVB -T) .. or even from the comfort of sitting in an armchair (.. is the world of sticks USB to win and also that the next PC with circuits native LTE / WiMAX).
I have always been a supporter of WiMAX technology until the FCC in the United States did not put in the auction of the 700 MHz band for mobile Internet applications (an event that immediately caught this blog!), And since then the bet, Europe and Italy, the new WiMAX networks on uncomfortable high frequency of 3.5 gigahertz (one that does not go well .. the walls ...) I immediately looked prematurely aged .. The owners of mobile networks, then, have not lost time and Electronics as Nokia Siemens and Ericsson have been reckless about the possibility, even the European Union (finally), to broadband IP services in the area of \u200b\u200bthe GOOD Super GSM or UMTS.
A LONG TERM EVOLUTION OF GSM, all-IP, so that they, like Intel, HAD TO BET ON WIMAX PROCESS FOR RAPID CONVERGENCE . The technology did the rest in terms of chips and systems of modulation, and now things are a little more clear, for goodness sake! The 2009 test of LTE are absolutely convincing.
The question must be seen in the context of the new EU policy on radio spectrum and in the true enjoyment of DIGITAL DIVIDEND for the new SUPER-UMTS services.
not that be done, but we are almost there (Italy permitting!):
By 2012, television broadcasting services across the EU will have completed the transition from analogue to digital technology. The switchover will release a significant amount of high quality radio spectrum which will be free for the deployment of new services and new technologies. This ‘digital dividend’ can boost both the broadcasting sector and the wireless communication industry, make a major impact on competitiveness and growth, and provide a wide range of social and cultural benefits. But gaining maximum advantage of this unique opportunity will require a coordinated European strategy for its future use.
Post Scriptum: paradossalmente, però, l'accesso a Internet da hot spots fissi nelle Città o nei Territori Wireless (basate ad oggi sul classico wifi o sulla libera tecnologia HIPERLAN to 2.4 GHz) are excellent, efficient and resilient infrastructure "WAITING FOR THE GENERATION 4, at low cost. Over all, the technologies on which they could build, and you are done, but the necessary wireless PRIVATE NETWORKS inter-communal for a wide range of public digital. These newly emerging networks such as WiMAX infrastructure Italian must find new paths of development and interaction with mobile networks ..
