IEEE 802.16 and WiMAX Forum LTE and LSTI Alliances How to Break Through Taiwan WiMAX Ecosystem What is 4G? ITU-Rs’ Perspective A high degree of commonality of functionality worldwide while retaining the flexibility to support a wide rage of services and applications in a. Capability of inter-working with other radio access systems. Capability of services within IMT and with fixed networks. Enhanced peak data rates 100Mbps for high and 1Gbps for low mobility What is 4G? ITU-Rs’ Perspective What is 4G? SDOs’ Perspective Technology Enablers plan the future in advance at SDO and Industry Alliances meetings Samsung LTE Product Roadmap 小結 From ITU-R Perspectives: IMT-Advanced Spectrum was finalized at WRC07. IMT-Advanced Radio Access Technology is now under-progress with SDOs. Specification Recommendation will be expected by year 2011. From SDO’s Perspective: LTE-Advanced and WiMAX 16m (not Rel. 2) will be submitted and evaluated by mid of 2010. From Alliances Perspective: WiMAX Rel. 2 will only be ready for commercial phase after 2012. LTE and LTE-Advanced Industrial Evaluation Group (LSTI) is expected to have Friendly Trial ready by year 2010. LTE-Advanced (Rel. 10) will be released a year later. Operators should rather wait to avoid double investment. From Global Operator’s Perspectives: Timing of the roll-out and uptake of 4G application and services should follow: Mobile Computing, Mobile (2.0) Services and Mobile CE Devices and data Business model to be suitable for High throughput at Mobile.
