4G
4G: essentially the same thing as Beyond 3G, refers to the fourth generation of cellular wireless and is a successor to 3G and 2G standards. The rest of this article associates 4G with International Mobile Telecommunications-Advanced (IMT Advanced), though 4G is a broader term and could include standards outside IMT-Advanced. A 4G system may upgrade existing communication networks and is expected to provide a comprehensive and secure IP based solution where facilities such as voice, data and streamed multimedia will be provided to users on an “Anytime, Anywhere” basis and at much higher data rates compared to previous generations.
