MIMO and smart antenna technologies for 3G and 4G

Abstract

Evolution of wireless access technologies is about to the reach its fourth generation (4G). The adaptation of smart antenna techniques in future wireless systems is expected to have a significant impact on the efficient use of the spectrum and transparent operation across the multi technology wireless networks. With the rapid growth of wireless data traffic operators are anxious to quickly expand the capacity of their wireless networks. To address these 3GPP standards have incorporated powerful techniques for using so-called smart antennas. This paper focuses on the practical aspects of deploying smart antenna systems in the existing Radio Access Systems (RAS). Smart antenna techniques, such as multiple-input multiple-output (MIMO) systems, can extend the capabilities of 3G and 4G systems to provide customers with increased data throughput for mobile high-speed data applications. © 2011 Springer-Verlag.
