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. 2

• M B N need to support higher data rate requirement.

• Efficient radio access technology combined with more spectrum

availability is required.

WIRELESS EVOLUTION

The generation Access protocols Key features Level of evolution

1G FDMA Analog, primarily voice, less secure, support for low bit

rate data

Access to and roaming across single type of analog wireless

networks

2G&2.5G TDMA,CDMA Digital, more secure, voice and data

Access to and roaming across single type of digital wireless

networks and access to 1G

3G&3.5G CDMA 2000,W-CDMA,HSDPA,TD-SCDMA

Digital, multimedia, global roaming across a single type

of wireless network(for example, cellular), limited IP

interoperability,2Mbps to several Mbps

Access to and roaming across digital multimedia wireless networks and access to 2G

and 1G

4G OFDM Global roaming across multiple wireless networks,

10Mbps-100Mbps, IP interoperability for seamless

mobile internet

Access to and roaming across diverse and heterogeneous

mobile and wirelessBroadband networks and access to 3G,2G and 1G

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

• 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

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

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

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.

• To incorporate directional beam forming

• RX and TX communicate via Main lobes.

• Steering antenna is required.

• Smart antenna is required

14

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

• 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

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

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.

18

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.
