2.1. 4G FEATURES
Convergence of services: The idea of convergence means that creating the atmosphere that can eventually provide seamless, high reliability and quality of mobile communications services and broadband ubiquitous services over wired and wireless convergence without the problem of limited land space and, through the ubiquitous connectivity. The convergence between industries also accelerated by the formation of alliances through participation in various projects to provide converged services. 4G mobile systems are mainly characterized by a horizontal communication model, where access technologies such as different cellular, wireless, wireless LAN type, short-range wireless connectivity, and cable systems will be combined into a common platform to complement between them in the best possible way for the service requirements of different situations and environments of radio. The development is expected to inspire the progressive trend of information technology is far from being the current focus of the technical convergence fully mobile and widespread media. The trends from the perspective of services include the integration of services and the convergence of service delivery mechanisms. According to these trends, the mobile network architecture will become flexible and versatile, and new services will be easy to implement.


Broadband Services: Broadband is a basis for the purpose of enabling multimedia communications, including video service, which requires transmission of large amounts of data, but, of course, calls for the media convergence issue, based in the transport of packages, advocating the integration of different media in different qualities. The position growing broadband services as asymmetric digital subscriber line (ADSL) systems and optical fiber access and office or home LAN is expected to lead to a demand for similar services in the communication environment mobile. 4G characteristics of application services give broadband service benefits:

1) Low cost to make broadband services available to users to exchange various types of information is necessary to reduce costs considerably in order to keep the cost or below cost of existing service.
2) Wide Area Coverage One of the characteristics of mobile communications is that it is the availability and omnipresent. This advantage is important for future mobile communications. In particular, it is important to maintain the service area in which the terminals of the new system can be used during the transition from existing system to a new system.
3) Wide range of services is mobile communication skills for different types of users. In the future, we hope that the advanced system performance and functionality to introduce a variety of services not only phone service tradicional.Los services should be easy for anyone to use.


INTERACTIVE BCN (ALL-IP) with home networks, telemetry, SENSOR-NETWORK SERVICES: Since technologies are becoming more collaborative and essential. The development of all network services based on All-IP network is needed for more converged services. IP-based unified network for services far beyond the convergence of quality land through active access is what the broadband convergence network is. ALL-IP convergence and Next Generation IP-based network cable or backbone cable, which can be implemented quickly if convergence. All IP networks and IP multimedia technology services are the main trends in the wired and wireless network. The idea of broadband network convergence (BCN) fit into the provision of a common service architecture, unified and flexible that it can support multiple types of services and management applications across multiple types of transport networks.The main purpose of giving effect to service more interactive 4G network driven by the convergence of broadband is its applicability to home networks, telemetry, and the sensor network. Partnership will provide a converged network and application service more beneficial, especially if the computer is broadband users and their suppliers. To give more emphasis on this service request, an example is the creation of home networks and their implementation is bound to give more benefits to users and society in terms of broadband connectivity. Much more than the implementation of broadband convergence network, the application of telemetry will emphasize more tangible in the implementation of 4G mobile technology.


FLEXIBILITY AND PERSONAL SERVICE:
The main concern in the design of network security is the flexibilidad.sistemas 4G 4G support comprehensive and personalized services, providing system stability
performance and service quality. To support multimedia services, high speed data reliably good system will be provided. At the same time, a low rate of data transmission costs are maintained. In order to meet the demands of these diverse users, service providers should design personal and customized services for them. Personal mobility is a concern in the management of mobility. Personal mobility focuses on the movement of users instead of users
terminals, and is the sending of personal and
customized operating environments. Implementation of SDR to 4G offers an advantage of the benefits to service providers, manufacturers and users, and, for service providers;
1) Improving the effectiveness of infrastructure resources.
2) High efficiency space
3) Reduce operating expenses appropriate to a reduced need for hardware updates to the site.
4) Reduce the cost of capital because of increased use of available network elements.
5) Improbable and faster time to market of new services and applications. The benefit of SDR for manufacturers is through a decrease in the number of independent platforms that will be necessary for the purposes of different wireless technologies.
