Li-Fi, An Internet Service 100 Times Faster Than WiFi

Wireless Fidelity or WiFi, as we know it, has changed the way Internet is accessed all over the world. The high-speed connectivity has allowed people from around the world communicate via Internet.

Now, what if we told you that a group of scientists in Estonia has developed a technology that is 100 times faster than WiFi? Seems unbelievable, right? Not at all. A company named Velmenni, based in Tallin, Estonia, has a new internet providing service termed as Li-Fi or Light Fidelity.

Light Fidelity uses Light Emitting Diodes (LED) to transfer signals from the router to the end user device at a speed of 1 gbps (Giga bytes per second).

Here are seven points about Li-Fi you must know:

1. The Li-Fi technology provides 100 times faster Internet than WiFi. It allows speed up to 224 gbps.

2. It requires an LED light source, an internet connection and a photo detector to spread the signals.

3. The Estonian company, Velmenni used this technology to merge the smart lighting system and Internet connectivity to increase its revenue and save energy.

4. Li-Fi uses the same technology as used in standard television or air-conditioner remote control.

5. The infrared beams of a remote control encode signals in light pulses and can transmit around 1,000 bits per second. On the other hand, an LED bulb can transmit signals at a speed of 1,000,000,000 bits per second.

5. The term Li-Fi was first used by Edinburgh University professor, Harald Haas, who demonstrated the system at the Technology, Entertainment and Design (Ted) conference in the year 2011.

6. The Li-Fi does not interfere with other radio signals such as broadband and WiFi. Hence, it can be used on aeroplanes as well. So, no more flight mode!

7. The downside of Li-Fi is that it cannot be used outside the house in daylight, as the sunlight would interfere with the LED signals. Besides, it cannot penetrate through walls like WiFi does, hence, the user needs to be in close proximity of the LED source to get uninterrupted signal.

Internet Neutrality – What is the Buzz?

Save the internet! Save the internet! This mantra seems to exist as the most apprehensive syllable uttered by the world. The internet essentially was rolled out decades ago with regular alterations and betterment to the structure over the years.


So what exactly is net neutrality? Almost a couple of months ago, some service providers and government administrations treated some parts of the internet with discrimination. Net neutrality is the brawl to make all data available on the internet uniformly.


The Concept of Open Internet
The theory of net neutrality proposes all data on the World Wide Web must be treated equally and must remain accessible to internet users at all times. However, some public and private administrative sectors believe that certain data from the internet must come at a premium. ISPs, government agencies and telecom operators have entire control over the internet’s content and can control the costs, speed and availability of various websites.

Fanatics strongly oppose this discriminating move and have shown grave dislike for the actions.

In a nutshell, net neutrality comprises about:

• All sites must remain uniformly accessible 
• Internet companies shall not entail telecom-style licensing
• Preference of speeding up websites must not prevail
• Free or paid websites must not prevail

Consequently, all users must have freedom to access websites without any obligation from government agencies, ISPs or telecom operators.


Hype in India about Net Neutrality
Telecom operators in India adhere to the guidelines laid by the TRAI (Telecom Regulatory Authority of India) and are pressing to introduce new principles for the internet that may stake or freedom for privacy and preferences. If this intention bears fruit, our Internet Service Providers will choose which portals or apps we can visit and the costs for each site.

Website owners and application publishers will have to pay each ISP individually to make your work visible to the users on their network. For instance, the Airtel network may charge it customers for using WhatsApp, whereas the Hike Messenger would be free as it is a product from Airtel.


What’s More Important?
The surge in wireless broadband connections has lead to intense debate and differences in outlooks. All odds are bending in favor of the customer and independent ISP companies are now withdrawing their programs. The internet is finally free as before and people can use it accordingly. Several ISPs such as Aadishesh have shown grave concern about Net Neutrality and have initiated several states with internet connection.
The conflict with net neutrality is not what people should brood over; instead, the prime focus should remain with pan-India internet connectivity for all.
