T10 - Smart Antennas for Wireless Systems
| • | Jack Winters, Motia, USA |

In this tutorial, we will discuss current and future antenna technology for wireless systems and the improvement that smart and adaptive antenna arrays can provide. We will describe standard cellular antennas, smart antennas using fixed beams, and adaptive antennas for base stations, as well as antenna technologies for handsets and other wireless devices. We will show the potential improvement that these antennas can provide, including range extension, multipath diversity, interference suppression, and capacity increase.
The issues involved in incorporating these antennas into wireless systems, including 2nd generation (CDMA, GSM, and IS-136), 3rd generation (WCDMA and EDGE), and future cellular systems, as well as other wireless systems, such as wireless local area networks (WLAN¹s) in different environments, such as rural, suburban, and urban areas, as well as indoors, will be described in detail. Theoretical, computer simulation, experimental, and field trial results will be presented. This tutorial should provide a basic understanding of the antenna technology options and their potential in wireless systems. |
Dr. Jack H. Winters received his Ph.D. in Electrical Engineering from The Ohio State University in 1981 and was then with AT&T in the research area for more than 20 years. At AT&T, he was Division Manager of the Wireless Systems Research Division of AT&T Labs-Research. Currently, he is Chief Scientist at Motia, where he is involved with smart antennas for wireless systems. He is a Fellow of the IEEE, an IEEE Distinguished Lecturer for both the IEEE Communications and the Vehicular Technology Societies, Area Editor for Transmission Systems for the IEEE Transactions on Communications, and New Jersey Inventor of the Year for 2001.
