Abstract

We are living in a convergence era with a full blossom of mobile communication devices, inter-net protocol (IP), computing and broadcasting. 4G (in ITU-word, IMT-Advanced) technology roadmap is generally conceived to be two major paths, namely a conventional cellular-based path (3G, 3G LTE and LTE-Advanced) and an IP –based path (IEEE 802.16e (mobile WiMAX) and 802,16m evolution). ITU-R finally allocated global broadband spectrum for IMT services out of WRC-07 and is undertaking a major milestone of MT-Advanced standardization. Until the last October Seoul meeting, WP 5D has completed IMT-Advanced requirements and evaluation doc-uments. And both 3GPP and IEEE 802.16 plan to submit their IMT-Advanced technology proposal by mid of 2009. And IMT-Advanced Specifications plan to be completed 1Q 2011,
In Korea, mobile WiMAX service will be fully deployed in major cities by end of 2008, and in US, Sprint-Nextel 4G (mobile WiMAX) network is being deployed nation-wide in a few years with a new open access concept. In open access, a proliferation of many different mobile devices is allowed to be connected to the network.
In summary, both 3G LTE-Advanced and IEEE 802.16m evolution are promising standard can-didates for IMT-Advanced. Standards development may follow the ITU time schedule. However, still new business applications and service developments are very much needed for differentiat-ing IMT-Advanced from 3G.
