The fourth generation 4g mobile communications

Comments While most of us are used to getting high speed Internet connections at home, the office or even the local coffee shop, once we are on the road those high speeds have to stay behind.

The fourth generation 4g mobile communications

With this said OWA model, a fourth generation mobile communication system is defined and developed. Field of the Invention This invention relates to the architecture and system model to implement a converged broadband wireless communications supporting various wireless radio transmission technologies including cellular mobile standards, portable wireless access standards and any user-defined new wireless standards by constructing an Open Wireless Architecture OWA platform in the parts of base-band processing, radio frequency, controller, network interface as well as service applications, etc.

Based on this OWA model, this invention defines a new product for the Fourth Generation 4G mobile communications including base station and terminal design. Description of the Prior Art The number of subscribers for mobile communications has increased much faster than predicted, particularly for terrestrial use, and the majority of traffic is changing from speech-oriented communications to multimedia communications.

It is generally expected that the number of portable handsets will exceed the number of PCs connected to the Internet.

3G capabilities

The step towards Fourth Generation mobile 4G or beyond 3G B3G has been taking to support advanced and wideband multimedia services. The interworking between 4G and other access systems in terms of horizontal and vertical handover and seamless services with service negotiation including mobility, security and quality-of-service QoS will be a key requirement.

Therefore, the most important issue in developing future 4G mobile systems is the architecture based on the converged broadband wireless platform and targeted for Open Wireless Architecture OWA. Wireless applications in strong support of vehicular and pedestrian users has emerged as a cornerstone of new generation communications.

When coupled to the emerging broadband wireline infrastructure, wireless access and wireless mobile will extend the benefits of multimedia services from the home and business environments, ushering in an era of anyone, anywhere, anytime, any media communications.

The fourth generation 4g mobile communications

In future 4G mobile communications, two economically contradictive demands will arise; ubiquity and diversity. Open, global and ubiquitous communications make people free from spatial and temporal constraints.


Versatile communication systems will also be required to realize customized services based on diverse individual needs. The flexibility of wireless mobile IT wmIT can satisfy these demands simultaneously.

Therefore, wmIT can be seen to play a key fundamental role in the 21ST century. The user expectations are increasing with regard to a large variety of services and applications with different degree of quality of service, which is related to delay, data rate and bit error requirements.

Therefore, seamless services and applications via different wireless access systems and technologies that maximize the use of available spectrum will be the driving forces for future wireless developments.

OWA will eventually become the global industry standard to integrate various wireless air-interfaces into one wireless open terminal where the same end equipment can flexibly work in the wireless access domain as well as in the mobile cellular networks.

As mobile terminal rather than wireline phone will become the most important communicator in future, this single equipment with single number and multiple air-interfaces powered by OWA will definitely dominate the wireless communication industries.

The fourth generation 4g mobile communications

The OWA platform can not only improve the spectrum efficiency, increase wireless data-rate and optimize network resource, but also provide cost-effective solution to enhance the wireless communication services which is very essential for the next generation business model of mobile communications.

The wireless communications, in the last twenty years, have evolved from a simple transmission technology to a more complicated system technology.

With the rapid development in different industrial applications, lots of wireless standards have been defined on the world-wide basis, and it is becoming very hard to have all the countries and industries to agree on the single wireless standard internationally because of different interests behind the scene.

Therefore, the initial objective of the ITU international telecommunications union IMT single standard for third-generation 3G had been failed, which resulted in multiple standards across the global. This is very important because the wireless communications is much different from wireline communications, and it develops very rapidly.

The major problems remaining in the 3G solution include but not limited to: Spectrum management and regulation. Compatibility between functional segments.

Currently, there is at least one wireless standard coming out every month on the worldwide basis which may include international or regional standard.
