• The new generation of wireless is intended to complement and replace the 3G systems.

• The future 4G infrastructure are aimed to consist of a set of various networks using IP as a common protocol so that users are in control, because they will be able to choose every application and environment

• New 4G networks are designed to provide a wide variety of new services, such as high-quality voice to high definition video to high-data rate, and smoother and quicker handoff and will focus on ensuring seamless service across a multitude of wireless systems and networks

• The 4G technology is designed for seamlessly integration terminals, networks and applications to meet ever increasing subscriber expectations.

• The key concept is integrating terminals, networks and applications to meet ever increasing subscriber expectations.

• The key concept is integrating the 4G capabilities with all of the existing mobile technologies through advanced technologies. Applications adaptability and being highly dynamic are the main features of 4G services of internet to users.

• The fourth generation will encompass all system from various networks, public to private, operation-driven broadband networks to personal areas, and to ad hoc networks.

• 4G systems will interoperate with 2G and 3G system as well as with digital (broadband) broadcasting systems

• 4G systems will be fully IP based wireless Internet. This all-encompassing integrated perspective shows the broad range of systems that the fourth generation intends to integrate from satellite broadband to high altitude platform to cellular 3G and 3G systems to WLL (wireless local loop) and FWA (fixed wireless access) to WLAN and PAN (Personal Area Network) all with IP as the integrating mechanism.

• With 4G a range of new services and models will be available. These services and models need to be further examined for their interface with the design of 4G systems.
