3G Americas today published a new white paper entitled Defining 4G: Understanding the ITU Process for the Next Generation of Wireless Technology. The white paper provides the factual description of how IMT-Advanced or 4G will someday be defined by the International Telecommunications Union (ITU). ITU is the internationally recognized authority that will produce the official definition of the next generation of wireless technologies beyond IMT-2000 or 3G.
