SMART ANTENNA SYSTEMS (an overview)
[attachment=53223]
Smart Antenna Array:
antenna array with a digital signal processing capability to transmit and receive in an adaptive and spatially sensitive manner.
USAGE
Applications to:
cellular and wireless networks
radar
electronic warfare (EWF) as a countermeasure to electronic jamming
satellite systems
WHY SMART ANTENNA ARRAYS?
Higher Capacity
Higher Coverage
Higher bit rate
Improved link quality
Spectral efficiency
Mobility
Aim :
to maximize the antenna gain in the desired direction
to minimize the gain in directions of interferers
Smart Antennas for Base Stations
the idea of smart antennas is to use base station antenna patterns that are not fixed, but adapt to the current radio conditions
can be visualized as the antenna directing a beam toward the communication partner only
