3. INTRODUCTION
Smart antennas in mobile communications that enhances the
capabilities of the mobile and cellular system such as
 Faster bit rate.
 Multi use interference.
 Space division multiplexing (SDMA).
 Adaptive SDMA.

4. WHAT IS A SMART ANTENNA
 Also called adaptive array antennas
Combines an antenna array with a digital
signal-processing capability to transmit and
receive in an adaptive, spatially sensitive
manner.
They change their antenna pattern
dynamically to adjust to the noise,
interference in the channel.

8. ADVANTAGES
 Enhance coverage through Range extension.
 Fully controllable by software so less manual operations.
 Reduction in transmitted power.
 Reduce co-channel interference (CCI) and multipath
interference.
 Improve system capacity.

9. DISADVANTAGES
 Their transceivers are much more complex than
traditional base station transceivers.
 Expensive.

10. FUTURE SCOPES
In mobile
handsets to
achieve
much better
performance.
4G system
with 1 Gbit/s
data rate and
frequency
20-100Mhz.
Enhancing
spectral
density in
wireless
system.
Use of smart
antenna in existing
systems will
reduce power
consumption and
interference.
