It is a visible light communication system that uses light from light-emitting diodes (LEDs) as a medium to deliver networked, (instead of radio frequency waves) that is part of the Optical Wireless Communications technologies, which carries much more information, and has been proposed as a solution to the RF-bandwidth limitations. Also deliver mobile, high-speed communication in a similar manner as Wi-Fi and is bidirectional.

The Professor Harald Haas of the University of Edinburg and his team have made another breakthrough in Li-Fi by demonstrating that up to 1.1 Gbps can now be transmitted using light waves from micro LEDs over a distance of 10m using less than 0.5W power. This proves the point that lights can be dimmed down while high data rates and coverage are maintained.

About the Li-Fi industry there’s a company the name PureLiFi in which the Prof. Hass is a co-founder, already start to sell a product the name Li-1st which is the world’s first commercially available high-speed, bidirectional optical wireless system that can operate with a range of commercially available LED luminaries. It provides an IP-enabled ceiling unit and a desktop device that can be connected via USB to client devices. This industry is expected to grow up to $6 billion by 2018.

This could be the future of the internet and the networks systems including the wireless connections, we just need to wait a couple months or years to see what is going to be in the future and how far we’ll get.

...Li-Fi Technology. T.Ganesh ECE- A tganesh.gopi140@gmail.com Abstract Li-Fi (Light Fidelity) is a bidirectional, high speed and fully networked  and a subset of optical wireless communications (OWC) and could be a complement to RF communication (Wi-Fi or Cellular network), or even a replacement in contexts of data broadwireless communication technology similar to Wi-Fi. The term was coined by Harald Haas  and is a form of visible light communicationasting. It is so far measured to be about 100 times faster than some Wi-Fi implementations, reaching speeds of 224 gigabits per second. It is wireless and uses visible light communication or infra-red and near ultraviolet (instead of radio frequency waves) spectrum, part of optical wireless communications technology, which carries much more information, and has been proposed as a solution to the RF-bandwidth limitations. This OWC technology uses light from light-emitting diodes (LEDs) as a medium to deliver networked, mobile, high-speed communication in a similar manner to Wi-Fi. The Li-Fi market is projected to have a compound annual growth rate of 82% from 2013 to 2018 and to be worth over $6 billion per year by 2018. Whether you‘re using wireless internet in a coffee shop, stealing it from the guy next door, or competing for bandwidth at a conference, you‘ve probably gotten frustrated at the slow speeds you face when more than one device is tapped into the network. As more and more people and their many devices access...

It is low-energy, non-ionizing radiation which can penetrate many non-polar, non-conducting materials such as clothing, paper, masonry or plastic. They can penetrate fog and clouds. Their wavelength corresponds revealingly with bio molecular vibrations. Terahertz radiation, also known as t-rays, has wavelength of 3-100 cm-1. Terahertz radiation was discovered in 1896. Unless they're at a temperature of absolute zero (−273.16°C), all objects, animate and inanimate, give off terahertz radiation (called T-rays), the heat from molecular vibrations. No one knew how to make T-rays bright enough to actually use in the everyday world. Attempts with semiconductors produced only wimpy T-rays, 1/2,000th of a watt at most. One way to make terahertz radiation...

Openradio and Software Defined Cellular Wireless Networking

...OpenRadio and Software Defined Cellular Wireless Networking As with most aspects of computer science, wireless network technology has evolved over the years by way of competing proposals and protocols, developed within academia, industry, or often through collaboration of the public and private sectors. As public adoption of computer networks increased, the demand for methods of connecting these networks and allowing users to access their resources led engineers and theoreticians to adapt existing electromagnetic radiation to transmit computer data over the same media which had previously been used to broadcast audio and video signals. For as widespread as the use of these technologies has become, most of the advancement and innovation still comes from within a relatively small community of experts in and around Silicon Valley. The subject of this report is one such collaboration known as the Open Networking Research Center, or ORNC, a joint task force between Stanford University and University of California at Berkeley, sponsored by prominent technology companies such as HP, Intel, Google, Cisco and VMWare. One of the projects that ONRC is working on is to develop a software defined networking solution for cellular wireless data networks, which they refer to as OpenRadio. This report will focus on what ONRC perceives as the problem or shortcoming with the current TCP/IP infrastructure which supports cellular wireless, what they propose as their solution, and how close they are...

...o there are many issue with wireless devices, I am going to discuss and also going to throw light on new possibilities. These are main 4 Issue with wireless technology we are having these day 1. Capacity We are transmitting these wireless data in form of radio wave, we all knows these are limited, scarce, and expansive and no hope for further expansion as per our need. These limitation is not able to full fill our current monthly data transmission demand and we are no doubt running out of spectrum. 2. Efficiency There is another problem, efficiency. These base stations consume lots of power every hour. Interesting thing is that most of the power is not used for transmitting radio waves, but to cool down the base stations. Thus efficiency of such base stations is only about 5%, that means a big problem. 3. Availability You can’t use your wireless devices in your Flight, hospitals, in military prone areas for security issue. 4. Security Security is another issue, these penetrating and scattering radio waves have no controls in boundaries, they goes off the range we use, even consumes power too. Even somebody can make misuse of these radio waves, Looking to another corner, we have 20 billion of Light bulbs deployed across the world in current infrastructure. That’s what I am going to cover in my post. We have electromagnetic spectrum, where we have Radio waves and visible light, Comparing their availability, bamm, we have 10,000 times more visible...

...gadgets though provide us with the best of functionalities, the hassles of managing them cannot be denied. There is no single device that offers the best features of all the gadgets and hence a need of integrating them into one arises. With the already existing concept of internet of things, the need of the hour is to enable this technology to understand and analyse human habits and act accordingly. * The need of a common platform that interacts with all the devices and supports the interaction of all gadgets amongst themselves. E.g. here we wish to have a network pool registered with the Master Controller which enables connectivity and interaction of all the devices with each other. So a DSLR connected to a Smart TV through the master controller shall enable us to see the captured moments on the big screen. * The humanoid thinking of the Master Controller is what we intend to achieve in order to derive the maximum value of all the devices. The devices shall in this case act as per my thoughts. UNDERSTANDING THE APPROACH Here we see the Master Controller (MC) connected to all the devices through the Li-Fi ("light fidelity" technology, that can be a complement of RF communication or a replacement in contexts of data broadcasting. It is high speed and bidirectional which carries much more information and has been proposed as a solution to the RF-bandwidth limitations) and Bluetooth, the devices in turn are connected to this common pooled network established by the...
