Antennas have been the most neglected of all the components in personal communications systems. This tutorial is an introduction to the essential concepts of smart antenna systems and the important advantages of smart antenna system design over conventional omnidirectional approaches. The discussion also differentiates between the various and often dissimilar technologies broadly characterized today as smart antennas.
Intelligent Antennas: Spatial Division Multiple Access (PDF)
There are many methods for utilizing data from antenna arrays in wireless communications systems, the most
advanced of which is called spatial division multiple access (SDMA). This essay describes the principles of
SDMA, explains the benefits of SDMA, and compares SDMA with other smart antennas.
IntelliCell®: A Fully Adaptive Approach to Smart Antennas (PDF)
Smart antenna systems utilize multiple antennas at base stations or handsets to better pinpoint or focus radio
energy and thereby improve signal quality. To some extent, the phrase "smart antennas" is misleading. There is
nothing smart about the antennas themselves. What's smart is the sophisticated signal processing applied to
simultaneous signals from an array or collection of multiple antennas. Through eight years of practical and
field implementation, IntelliCell® has been perfected to make smart antennas practical and cost-effective in
actual commercial cellular systems.
