4G Wireless Technology
4G wireless technology refers to the fourth generation of cellular wireless standards. It is a successor to 3G and 2G standards. Its main aim is to provide a wide range of data rates up to ultra-broadband (gigabit-speed) Internet access to mobile as well as stationary users.
A 4G cellular system must have target peak data rates of up to approximately 100 Mbit/s for high mobility such as mobile access and up to approximately 1 Gbit/s for low mobility such as nomadic/local wireless access, according to the ITU requirements. Scalable bandwidths up to at least 40 MHz should be provided. A 4G system is expected to provide a comprehensive and secure all-IP based solution where facilities such as IP telephony, ultra-broadband Internet access, gaming services and HDTV streamed multimedia may be provided to users.
