This chapter provides an overview of non-telephony-oriented wireless communication systems. We present the main techniques employed or under study, with special emphasis on the emerging technologies that are changing the mobile wireless communications capability from voice applications to broadband multimedia, towards the targeted “Multimedia Wireless Communications Anytime and Anywhere”. The topic is vast and changing rapidly, and consequently this brief chapter cannot be exhausting. For this reason the reader who wants to know more is invited to refer to specific journals covering wireless communications, mainly by the Institute of Electrical and Electronic Engineers (IEEE), some listed at the end of this chapter, which provide up-to-date research results or tutorial overviews of the latest developments. In this chapter we first review in Section 1 some basic facts about wireless communications, including technologies such as multiple antennas and multicarrier modulation. In Section 2 we describe the main characteristics of current wireless systems, with a discussion on possible evolutions towards cognitive radio. This chapter assumes the reader is familiar with basic concepts of electrical communication systems.

Abstract
This chapter provides an overview of non-telephony-oriented wireless communication systems. We present the main techniques employed or under study, with special emphasis on the emerging technologies that are changing the mobile wireless communications capability from voice applications to broadband multimedia, towards the targeted “Multimedia Wireless Communications Anytime and Anywhere”. The topic is vast and changing rapidly, and consequently this brief chapter cannot be exhausting. For this reason the reader who wants to know more is invited to refer to specific journals covering wireless communications, mainly by the Institute of Electrical and Electronic Engineers (IEEE), some listed at the end of this chapter, which provide up-to-date research results or tutorial overviews of the latest developments. In this chapter we first review in Section 1 some basic facts about wireless communications, including technologies such as multiple antennas and multicarrier modulation. In Section 2 we describe the main characteristics of current wireless systems, with a discussion on possible evolutions towards cognitive radio. This chapter assumes the reader is familiar with basic concepts of electrical communication systems.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
