4G and 5G communication technology in Malaysia

Abstract

The rapid growth of wireless networks and services, accelerated by the third-generation mobile communication system, is ushering in the era of the fourth-generation mobile communication system and even further to fifth-generation. Wireless Communication systems are evolving to meet the ultimate goal, to allow ‘anywhere, anytime, anything, by anyone’ communication customized to a particular subscriber’s preferences, location, and social behavior at a very high data rates transfer [1]. To reach this goal, much effort is still underway. Technologies employed by 4G may include SDR (Software-defined radio) receivers, OFDM (Orthogonal Frequency Division Multiplexing), OFDMA (Orthogonal Frequency Division Multiple Access), MIMO (multiple input/multiple output) technologies, UMTS and TD-SCDMA. All of these delivery methods are typified by high rates of data transmission and packetswitched transmission protocols. 3G technologies, by contrast, are a mix of packet and circuit-switched networks [2].
