This document discusses the significance of nanotechnology for future wireless devices and communications. It begins with an introduction explaining how nanotechnology could help address constraints on size and power consumption for mobile devices. It then provides background on nanotechnology, including its history and how it works at the nanoscale. The document outlines several ways nanotechnology could improve wireless devices, such as through new nanosensors, solutions for radio frequency challenges, increased speed and memory, and improved power and thermal management. It also discusses some of the challenges and impacts of nanotechnology on various industries. In conclusion, the document argues that nanotechnology research should focus on developing sustainable and recyclable electronics materials to help address environmental challenges.

- 1. SIGNIFICANCE OF NANOTECHNOLOGY FOR FUTURE WIRELESS DEVICES AND COMMUNICATIONS BY VAGGU SRIKANTH-13H61A04P8 UNDER THE GUIDANCE OF Mr.P.Ramakrishna Associate Professor Department of ECE
- 2. CONTENTS ABSTRACT INTRODUCTION WHAT IS NANOTECHNOLOGY HISTORY OF NANOTECHNOLOGY WHY NANOTECHNOLOGY HOW IT WORKS NANOTECHNOLOGY FOR WIRELESS DEVICES FUTURE IMPACTS AND CHALLENGES CONCLUSION REFERENCES
- 3. ABSTRACT The devices in the future have to become more efficient, and easier to use. This Concept reviews and examines the profound impact that nanotechnology would have on mobile devices in particular and future wireless devices in general.
- 4. INTRODUCTION One of the fundamental visions of the wireless industry is to have ambient intelligence to serve the user in an intelligent way. Mobility puts constraints on size and on the power consumption. Nanotechnology could provide solutions for problems with existing systems in ambient intelligence
- 5. WHAT IS NANOTECHNOLOGY ? Nanotechnology is a branch of science and engineering devoted to the design and production of extremely small electronic devices and circuits built from individual atoms and molecules.
- 6. HOW SAMLL ARE NANOPARTICLES? A Human Hair is about 100,000µm wide
- 7. HISTORY OF NANOTECHNOLOGY Worlds smallest logo made with only 35 atoms Moving a Xe atom on a nickel crystal to manipulate individual atoms of Ni surface
- 8. WHY NANOTECHNOLOGY ? To make better products: smaller, cheaper, faster and more effective. (Electronics, catalysts, water purification, solar cells, coatings, medical diagnostics & therapy, and more) To introduce completely new physical phenomena to science and technology.
- 9. MAKING NANOSTRUCTURES: NANOMANUFACTURING TOP DOWN APPROPACH BOTTOM UP APPROACH
- 10. HOW THESE STUFF WORKS In 1959 Richard Feynman, the Nobel prize winning physicist, said that nothing in the laws of physics prevented us from arranging atoms the way we want. If we rearrange the atoms in coal, we get diamonds. If we rearrange the atoms in sand (and add a pinch of impurities) we get computer chips. If we rearrange the atoms in dirt, water and air we get grass.
- 11. NANOTECHNOLOGY FOR WIRELESS DEVICES Nanosensors: One of the key requirements for embedding intelligent and autonomous devices into physical objects of the world requires that devices should adapt to their environment and become a part of the network of devices surrounding them. Such a system cannot be configured manually by using top down approach.
- 12. CONT’D Solutions for Radio: Range and interference avoidance, along with processing speed are the challenges posed by RF operation in the GHz frequency range. Since the radio frequency decides the basic clock speeds, the frequency at which certain physical and medium access control layer signal processing algorithms run per second is also determined by it. Here nanotechnology could be of great assistance.
- 13. CONT’D More Speed, Less Energy: The constantly increasing wireless communication speeds require increasing amount of computation with limited power. It has become possible to follow the Moore’s law and to provide electronics with all the time increasing performance with reduced price due to continuous innovation. Due to the limitations of the manufacturing technology the current approach of simply reducing the transistor size seems to come to an end.
- 14. CONT’D More Memory: As of today, to store data, videos, music and pictures from a number of different applications mobile phones require a substantial amount of storage capacity. Considering, wider use of different tools which allow users to create their own content and the need for fast wireless links for loading of external content, we can easily expect that mobile phones will require up to 10 GB internal mass memory for short term and 50-100GB for mid and long terms.
- 15. CONT’D Power and Thermal Management : The very large surface area of nano structured materials would facilitate in the development of energy and power sources. This would be beneficial for different power harvesting devices, for the battery technologies and fuel cells; Nanotechnologies will thus pave the way for developing hybrid energy solutions.
- 16. CONT’D Current Players: 1. NOKIA 2. DATOOS
- 17. FUTURE IMPACT ON INDUSTRIES The research community is vigorously pursuing hundreds of applications in Nano materials and Nano electronics. Nanotechnology has an impact on all industries: ceramics, metals, polymers, and biomaterials. New materials are the basis of major technological researches. In the coming future nanotechnology will certainly have a colossal effect on the above mentioned industries. Future research could drastically alter our approaches to manufacturing, electronics, IT and communications technology.
- 18. CHALLENGES The initial manufacturing cost could be very high because of the much research still that have to be done. Nanotechnology is an impending and fast growing field whose dynamics and prospects pose many great challenges not only to scientists and engineers but also to society at large. The introduction of nanotechnologies requires committed research of biological risks of nano materials, strategies for risk management in research, production, and recycling, and dissemination of objective information with the public arena.
- 19. CONCLUSION As opposed to focusing only on the potential hazards, we can also think about the use of nanotechnologies in a positive way. We can set the targets and objectives of the research so that they can help us to solve the environmental challenges that we will have to confront during the coming decades: we should develop new electronics materials that are easier to recycle and/or decomposable in biological processes, and optimize and minimize the energy consumption in the manufacturing of future materials and products.
