One need only look at the longevity of GSM 2G technology, and the indefinite need for 2G/3G multimode, for historical guidance.
The global recession will slow the rollout of 4G, due to less available capex funds,tuning and refining the complex technology and quality of service will take longer than expected, interoperability testing and the development of supply chains for devices, and all aspects of commercialization will also retard schedules. They always have, and will.LTE will be only found in urban islands, with multi-mode required for roaming and the filling of service voids. Every 3G/4G multi-mode device for decades will require the payment of 3G royalties to IDCC.I think your professor needs to get back to his studies.
