ABSTRACT The global bandwidth shortage facing wireless carriers has motivated the exploration of the underutilized millimeter wave (mm-wave) frequency spectrum for future broadband cellular communication networks. There is, however, little knowledge about cellular mm-wave propagation in densely populated indoor and outdoor environments. Obtaining this information is vital for the design and operation of future fifth generation cellular networks that use the mm-wave spectrum. In this paper, we present the motivation for new mm-wave cellular systems, methodology, and hardware for measurements and offer a variety of measurement results that show 28 and 38 GHz frequencies can be used when employing steerable directional antennas at base stations and mobile devices. INDEX TERMS 28GHz, 38GHz, millimeter wave propagation measurements, directional antennas, channel models, 5G, cellular, mobile communications, MIMO.

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.

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.

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.

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

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.

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 .

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.

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.
