Where can I use it?
If you have a compatible phone, and a Reliance Jio SIM, you should be able to use it just about anywhere. The commercial launch is going to be pan-India, and even the launch for employees is across India. In an emailed statement, from Mukesh Ambani at the last held Annual General Meeting, the company states that Jio will be present in all of the 29 states of India, with a direct physical presence in nearly 18,000 cities and towns of our nation. Jio's wireless footprint extends even further and covers over one lakh villages.
The statement adds that Reliance will cover 80 percent of India's population by the end of 2016, and to this end, has deployed a network of nearly 2,50,000km of fibre optics to create the backbone of the network.

hello friend's if you are confused from the adds published on the T.V of airtel 4G network speed then click the link below which redirect you to my youtube vedio comparing Airtel 4G and reliance JIO 4G  click here...

What will it cost?

There are several reports suggesting that the pricing could be as low as Rs. 300 to Rs. 500 for a bundle of data, e-commerce access, media, and payment services. How this all works out will be important to follow, particularly given the current attention to issues of net neutrality and zero rating.










Who else is offering 4G right now?

All the networks are upgrading to 4G services - Airtel presently has the most visible presence, and is charging the same rates for 4G as it does for 3G data. However, the company hasn't made any announcements about VoLTE yet. In a recent interview, Idea has also said that the ecosystem is not ready for VoLTE yet.
Idea has started the rollout of its 4G services, starting with South India, across 75 towns. Idea will expand northwards through South India by March 2016, and will launch services in other markets in India in a phased manner, covering 10 telecom circles by June 2016, it said. Idea is offering the same tariffs as existing 3G plans, along with special 4G Trial Packs to get users started on the network..
Vodafone also plans to roll out 4G in Metros by March, and has already started its 4G services in 10 towns in Kerala, and is also charging 3G rates for the network.

LiFI-Fastest network on the Earth

Jump to: navigation, search
Li-1st, the first Li-Fi equipment
Li-Fi (Light Fidelity) is a bidirectional, high speed and fully networked wireless communication technology similar to Wi-Fi. Coined by Prof. Harald Haas,[1] Li-Fi is a subset of optical wireless communications (OWC) and can be a complement to RF communication (Wi-Fi or Cellular network), or a replacement in contexts of data broadcasting. It is so far measured to be about 100 times faster than Wi-Fi, reaching speeds of 224 gigabits per second.[2]
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.[3] A complete solution includes an industry led standardization process.


Technology details[edit]

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.[4] 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.[5]
Visible light communications (VLC) works by switching the current to the LEDs off and on at a very high rate,[6] too quick to be noticed by the human eye. Although Li-Fi LEDs would have to be kept on to transmit data, they could be dimmed to below human visibility while still emitting enough light to carry data.[7] The light waves cannot penetrate walls which makes a much shorter range, though more secure from hacking, relative to Wi-Fi.[8][9] Direct line of sight isn't necessary for Li-Fi to transmit a signal; light reflected off the walls can achieve 70 Mbit/s.[10][11]
Li-Fi has the advantage of being useful in electromagnetic sensitive areas such as in aircraft cabins, hospitals and nuclear power plants[citation needed] without causing electromagnetic interference.[8][9] Both Wi-Fi and Li-Fi transmit data over the electromagnetic spectrum, but whereas Wi-Fi utilizes radio waves, Li-Fi uses visible light. While the US Federal Communications Commission has warned of a potential spectrum crisis because Wi-Fi is close to full capacity, Li-Fi has almost no limitations on capacity.[12] The visible light spectrum is 10,000 times larger than the entire radio frequency spectrum.[13] Researchers have reached data rates of over 10 Gbit/s, which is much faster than typical fast broadband in 2013.[14][15] Li-Fi is expected to be ten times cheaper than Wi-Fi.[7] Short range, low reliability and high installation costs are the potential downsides.[5][6]
PureLiFi demonstrated the first commercially available Li-Fi system, the Li-1st, at the 2014 Mobile World Congress in Barcelona.[16]
Bg-Fi is a Li-Fi system consisting of an application for a mobile device, and a simple consumer product, like an IoT (Internet of Things) device, with color sensor, microcontroller, and embedded software. Light from the mobile device display communicates to the color sensor on the consumer product, which converts the light into digital information. Light emitting diodes enable the consumer product to communicate synchronously with the mobile device.[17][18]

History[edit]

Professor Harald Haas, from the University of Edinburgh in the UK, is widely recognised as the original founder of Li-Fi. He coined the term Li-Fi and is Chair of Mobile Communications at the University of Edinburgh and co-founder of pureLiFi.[12]
The general term visible light communication (VLC), includes any use of the visible light portion of the electromagnetic spectrum to transmit information. The D-Light project at Edinburgh's Institute for Digital Communications was funded from January 2010 to January 2012.[19] Haas promoted this technology in his 2011 TED Global talk and helped start a company to market it.[20] PureLiFi, formerly pureVLC, is an original equipment manufacturer (OEM) firm set up to commercialize Li-Fi products for integration with existing LED-lighting systems.[21][22]
In October 2011, companies and industry groups formed the Li-Fi Consortium, to promote high-speed optical wireless systems and to overcome the limited amount of radio-based wireless spectrum available by exploiting a completely different part of the electromagnetic spectrum.[23]
A number of companies offer uni-directional VLC products, which is not the same as Li-Fi.[citation needed]
VLC technology was exhibited in 2012 using Li-Fi.[24] By August 2013, data rates of over 1.6 Gbit/s were demonstrated over a single color LED.[25] In September 2013, a press release said that Li-Fi, or VLC systems in general, do not require line-of-sight conditions.[26] In October 2013, it was reported Chinese manufacturers were working on Li-Fi development kits.[27]
In April 2014, the Russian company Stins Coman announced the development of a Li-Fi wireless local network called BeamCaster. Their current module transfers data at 1.25 gigabytes per second but they foresee boosting speeds up to 5 GB/second in the near future.[28] In 2014 a new record was established by Sisoft (a Mexican company) that was able to transfer data at speeds of up to 10Gbps across a light spectrum emitted by LED lamps.[29]

Standards[edit]

Like Wi-Fi, Li-Fi is wireless and uses similar 802.11 protocols; but it uses visible light communication (instead of radio frequency waves), which has much wider bandwidth.
One part of VLC is modeled after communication protocols established by the IEEE 802 workgroup. However, the IEEE 802.15.7 standard is out-of-date, it fails to consider the latest technological developments in the field of optical wireless communications, specifically with the introduction of optical orthogonal frequency-division multiplexing (O-OFDM) modulation methods which have been optimized for data rates, multiple-access and energy efficiency.[30] The introduction of O-OFDM means that a new drive for standardization of optical wireless communications is required.
Nonetheless, the IEEE 802.15.7 standard defines the physical layer (PHY) and media access control (MAC) layer. The standard is able to deliver enough data rates to transmit audio, video and multimedia services. It takes into account optical transmission mobility, its compatibility with artificial lighting present in infrastructures, and the interference which may be generated by ambient lighting. The MAC layer permits using the link with the other layers as with the TCP/IP protocol.[citation needed]
The standard defines three PHY layers with different rates:
  • The PHY I was established for outdoor application and works from 11.67 kbit/s to 267.6 kbit/s.
  • The PHY II layer permits reaching data rates from 1.25 Mbit/s to 96 Mbit/s.
  • The PHY III is used for many emissions sources with a particular modulation method called color shift keying (CSK). PHY III can deliver rates from 12 Mbit/s to 96 Mbit/s.[31]
The modulation formats recognized for PHY I and PHY II are on-off keying (OOK) and variable pulse position modulation (VPPM). The Manchester coding used for the PHY I and PHY II layers includes the clock inside the transmitted data by representing a logic 0 with an OOK symbol "01" and a logic 1 with an OOK symbol "10", all with a DC component. The DC component avoids light extinction in case of an extended run of logic 0's.[citation needed]
The first VLC smartphone prototype was presented at the Consumer Electronics Show in Las Vegas from January 7–10 in 2014. The phone uses SunPartner's Wysips CONNECT, a technique that converts light waves into usable energy, making the phone capable of receiving and decoding signals without drawing on its battery.[32][33] A clear thin layer of crystal glass can be added to small screens like watches and smartphones that make them solar powered. Smartphones could gain 15% more battery life during a typical day. This first smartphones using this technology should arrive in 2015. This screen can also receive VLC signals as well as the smartphone camera.[34] The cost of these screens per smartphone is between $2 and $3, much cheaper than most new technology.[35]
Philips lighting company has developed a VLC system for shoppers at stores. They have to download an app on their smartphone and then their smartphone works with the LEDs in the store. The LEDs can pinpoint where they are located in the store and give them corresponding coupons and information based on which aisle they are on and what they are looking at.[36]
