4G Technology Challenges SWOT and RRM Analysis Information Technology Essay

4G Technology Challenges SWOT and RRM Analysis. The approaching 4G (fourth generation) mobile communication systems are projected to solve still remaining problems of 3G (third generation) systems and to provide better QoS, speed and radio resource management (RRM) in heterogeneous network. The term 4G is used broadly to include several types of broadband wireless access communication systems, not only cellular telephone systems.

Global mobility support integrated wireless solution, Improvement of QoS parameter to improve spectral

efficiency and also RRm for core network. The 4G systems not only will support the next generation of mobile service,

but also will support the fixed wireless networks. This paper presents an overall vision of the 4G features, framework and integration of mobile communication. The features of 4G systems might be summarized with one word- Integration of available radio resources. The 4G systems are about seamlessly integrating terminals, networks and applications to satisfy increasing user demands.

GENERATION HIERARCHY:

The history of the generations of technologies in use before to the 4G technology has been discussed below:

First Generation (1G):

The first generation technology started its design in the 1970, and was dedicated for analog communications. It involved the amalgamation of basic TDMA an FDMA techniques. An important drawback of this generation was that these systems could easily be listened by third parties. Some of standards used in this generation were NMT, AMPS, Hicap, CDPD, mobitex.

Second Generation (2G):

He generation began with a decade later in the 1980s, and it was still voice centric but it highly scored upon the 1G as the conversations where digitally encrypted. The prominent developments that was on to revolutionize this technology where the introduction of GSM and SIM cards.

The major access technologies involve were: CDMA (Code Division Multiple Access) and TDMA (Time Division Multiple access). The 2G technology lacked the strength in the radio frequency signaling……………….
