Accessing information anywhere, anytime, with a seamless connection to a wide range of information and services, and 4g wireless system a large volume of information, data, pictures, video, and so on, are the keys of the 4G infrastructures.

The future 4G infrastructures will consist of a set of various networks using IP Internet protocol as a common protocol so that users are in control because they will 4g wireless system able to choose every application and environment.

Based on the developing trends of mobile communication, 4G will have broader bandwidth, higher data rate, and smoother and quicker handoff and will focus 4g wireless system ensuring seamless service across a multitude of wireless systems and networks.

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

These features mean services can be delivered and be available to the personal preference of different users and support the users' traffic, air interfaces, 4g wireless system environment, and quality of service.

Connection with the network applications can be transferred into various forms and levels correctly and efficiently.

Two competing standards were submitted in September as technology candidates for ITU-R consideration: Segue to 4G, the "next dimension " of wireless communication. In telecommunications, 4G is the 4g wireless system generation of cellular wireless standards.

It is a successor to the 3G and 2G families of standards.


A 4G system is expected to provide a comprehensive and secure all-IP based mobile broadband solution to 4g wireless system computer wireless modems, 4g wireless system, and other mobile devices. Facilities such as ultra-broadband Internet access, IP telephony, gaming services, and streamed multimedia may be provided to users.

Pre-4G technologies such as mobile WiMAX and first-release Long term evolution LTE have been on the market since [2] and [3][4][5] respectively, and are often branded as 4G in marketing materials.

On December 6,ITU announced that current versions of LTE, WiMax and other evolved 3G technologies that do not fulfill "IMT-Advanced" requirements could be considered "4G", provided they represent forerunners to IMT-Advanced and "a substantial level of improvement in performance and capabilities with respect to the initial third generation systems now deployed.

4G Wireless systems

New generations have appeared about every ten years since the first move from analog 1G to 4g wireless system 2G transmission in B, which was available in and offers However, the cell phone market only brands some of the IMT standards as 3G e.

An IMT-Advanced cellular system must fulfil the following requirements: Based on an all-IP packet switched network.


Dynamically share and use the network resources to support more simultaneous users per cell. Scalable channel bandwidth 5—20 MHz, optionally up to 40 MHz.

Smooth handovers across heterogeneous networks.


Ability to offer high quality of service for next generation multimedia support. Both technologies aim to reach the objectives traced by the ITU, but are 4g wireless system far from being implemented.
