2. INTRODUCTION
• Global bandwidth shortage.
• Wireless service providers (W.S.P) are facing many
challenges.
• Carrier frequency spectrum is between 700mhz to 2.6ghz.
• WSP requires simultaneous management of multiple
technologies.
• The base station should be backward compatible.

3. • M B N need to support higher data rate requirement.
• Efficient radio access technology combined with more spectrum
availability is required.

9. MILLIMETER(MM) WAVE
TECHNOLOGY
• What is MM wave?
•
• Next generation wireless technology that can provide
up to multi - Gbps wireless connectivity.
• Data rate is expected to be 40-100 times faster than today’s
wireless LAN technologies.
9

10. • Frequency range is from 25GHz to 300GHz.
• Wavelength is between 10mm to 1mm.
• Advantages of using this
•The radio spectrum is still rather undeveloped .
•Hence higher data rates is achieved.
•Security and privacy is better at mm-wave.
10

11. BANDWIDTH
• The spectral bandwidth of 5ghz being available in these
ranges.
• Current speeds of 1.25gbps full duplex.
• Potential throughput speeds of up to 10gbps.
• Expand channel band width way beyond 40mhz.
11

12. BEAM WIDTH INTERFERENCE
RESISTANCE AND SECURITY
• Narrow beam width (approx. 2 degree beam width).
• Reduces the interference.
• Spectrum reuse can be done.
• Cross-polarization techniques.
• Waves are highly directional.
• This offers high security.
12

13. PROPAGATION BEHAVIOR
• Based on the principle of line of sight (los)paths.
• It is required to use reflective paths by many object
• Reflections can establish non-los link.

14. • To incorporate directional beam forming
• RX and TX communicate via Main lobes.
• Steering antenna is required.
• Smart antenna is required
14

15. ANTENNA USED
• Narrow beam are the new feature of mm-wave.
• They reduces fading, multi-path, and interference.
• Antenna geometry is at chip size.
15

16. • The physical size of antennas are so small .
• Complex antenna arrays.
• Further integrate them on chip or pcb.
• It is possible to generate circuit which operate at mm wave
frequencies.
• Several array smart antenna which is adaptable in nature .
16

17. ADVANTAGES
• Larger bandwidth and Higher transmission rate.
• Capability of spread spectrum and is more immune to
interference.
• Extremely high frequencies allow multiple short-distance .
• Requires the narrow beam width.
• Higher the frequency - smaller the antenna and Reduces
hardware size.
17

18. DISADVANTAGES
• Higher costs in manufacturing .
• Extremely high frequencies- significant attenuation.
• Millimeter waves - long distance applications.
• The penetration power of mm wave -concrete walls is
known less.
• Interferences with oxygen & rain also.

19. CONCLUSION
• Millimeter wave - 5G cellular communication.
• Bandwidth and higher data rates .
• Further research is going on to remove the limitations.
• Reliability and efficiency in using these spectrum.
