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. Saturday, February 11, 2017 3

4. WHAT IS A SMART ANTENNA A lso called adaptive array antennas C ombines 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. Saturday, February 11, 2017 4

5. Saturday, February 11, 2017 5 WORKING OF SMART ANTENNA SYSTEMS

6. TYPES OF SMART ANTENNA SYSTEM Two main types: Switched Beam Adaptive Array Antenna Saturday, February 11, 2017 6 Switched Beam

7. Spatial Division Multiple Access Saturday, February 11, 2017 7

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. Saturday, February 11, 2017 8

9. DISADVANTAGES Their transceivers are much more complex than traditional base station transceivers. Expensive. Saturday, February 11, 2017 9
