How Facebook Changes the World We Live In

Facebook project updates

Mark Zuckerberg’s fame on the internet world is so phenomenal. Gifted with the ability to code a program while at Harvard, he and his friends made something that would change the world and Facebook is changing the world today undoubtedly. The world is united and reconnected by this number one social media platform, and it is serving the world for free! Yet Mark does not stop there, he is wanting more…

To Network the World

About two-thirds of the world population (or 4 billion) still has no access to the internet. Facebook (headed by Mark) aims to connect everyone by giving free access to the internet. Facebook has been working on so many projects and prototypes over the years in pursuit to making this goal a reality.

 

Their initiative called internet.org, along with partnerships with some biggest companies in telecommunication, aims to bring internet closer to people in the developing countries.

 

Facebook started in regions with existing infrastructures, it offers free basics service where people won’t need to pay a single cost. No money at stake but their usage is concentrated on what Facebook wants them to navigate. It clearly sets no competition invading the free basics service. This could also identify the factors that the developers would need to know in order to improve the said service.

 

Facebook has also started working on projects to provide internet access to those areas without any infrastructure yet – in remote areas.

The Aquila drone

Facebook presented its prototype last July 2015 to the world. The Aquila drone, having almost the same wingspan as Boeing 737 but lightweight at 400 kg., is designed to stay in the air for 90 days while circling at the radius of about 3 km. It rises daily from 18,000 m to 28,000 m in altitude and goes back to its starting altitude in order to save energy.

 

A laser invented by Facebook which can transmit info in gigabits will transmit data from a distance of 16 km or more. Then the drone sends the internet connection signal to the homes where it’s flying over. The drone should create 80 km perimeter on the area where it is moving.

Terragraph Technology

Facebook has also been working on two more projects on the same goal of connecting the world. A Terragraph technology is introduced which is made out of nodes that would be useful in crowded regions such as some places in India. This device signals can pass through buildings using special transmitters, with no trouble at 60GHz. Facebook wants to make sure that residents get broadband access without wiring their homes for net.

 

This is still under a test phase but the prototypes have already been made and testing is being coordinated with partners.

The Aries project

This is also a new project which attempts to hone the efficiency of the antennae and radio spectrum. The process is called a spatial multiplexing which tries to open 24 data channels in one antenna, and 96 numbers of antennae are to be installed on one tower only. This aims to expand broadband internet in rural areas with distanced receivers.

In Conclusion

These projects are no joke and as Facebook had announced about the funding of hundreds of millions of dollars to make these happen, I somehow see the sincerity of Facebook’s CEO to achieve his goal to make the world a better place.

 

Truly, internet helps us in our lives since it has been built and I sympathize for people who do not even know what an internet is. Having the courage to network everyone and connect all people to the world through the internet is another phenomenon to witness.  Well, I won’t be surprised if somehow Facebook will get profit from these projects (it’s still business and so the partnership happens), but not from the people who have been deprived of knowledge and world awareness all their lives. One day, and I believe it is going to happen soon, we will all be connected in this sense.

Latest Top 10 Countries Providing the Fastest Internet Speed

Top 10 countries with fastest net

The known average of loading a web page is at 6.3 megabits per second, and this was globally observed recently. While this seems fast enough to watch an online streaming movie and send an email at decent bytes, depending on how you are using the internet (i.e. uploading bigger files like videos), you might find that the average speed is still slow. This is even proven by the Massachusetts-based internet provider Akami Technologies in their latest study on how internet speeds still stack up in countries across the globe.

 

They recently released a report for the first quarter of this year, ranking ten countries having the fastest internet speed in the world. [Source: Business Insider]

 

#10 Finland

The speed of the internet in Finland is 17.7 mbps on the average and this is relatively fast.  Six years ago, the Ministry of Transport & Communications in the country offered every Finnish at least a 1 mbps connection. I bet the adjustments of the citizens of Finland were quite historic.

 

A 1 mbps net speed will not even give you a relaxed state of mind when watching a YouTube video, it’ll let you send an email in very slow pace.

 

#9 Czech Republic

The internet in Czech Republic is amazingly at 17.8 mbps on average. Their speed increased by 31% compared to last year’s. This is above what most Americans would consider average. This speed lets you watch HD videos without any buffering.

 

#8 The Netherlands

This country is at 17.9 mbps on average. The Netherlands also has the highest percentage of households using the internet among European Union two years ago, as per 2014 report.

 

#7 Japan

Japan is known to provide advancement in technology and is rich enough to support this aim. Ranking at 2nd in Q4 of 2015, Japan is now providing an internet speed average of 18.2 mbps. This is still relatively fast, allowing multiple people using the internet by watching Netflix, playing online games and surfing the net using multiple devices at a time without any delay.

 

#6 Latvia

Latvia’s average net speed is at 18.3 mbps which is nearly three times faster than the universal average.

 

#5 Switzerland

Switzerland has managed to increase their internet speed by 26% from last year, which gives an 18.7 mbps on average nowadays.

 

#4 Hongkong

The people living in Hongkong is having an average net speed of 19.9 mbps. This country is known as one of the first to reach 60 mbps in 2013.

 

#3 Sweden

Sweden has an increase of 32% from their last year’s net speed, enjoying a 20.6 mbps on average today. Wow, can’t wait to learn what I can do with the speed at the number one post!

 

#2 Norway

Norway has the largest growth of speed at 68%, giving its lucky citizens a speed of 21.3 mbps.

 

#1 South Korea

People who reside in South Korea enjoys the fastest internet speed in the world at 29 mbps.  This is 4.6 faster that the global average. Imagine downloading a HD movie (5000 mb average) at around 2.5 minutes! That’s how fast this speed is.

 

However, while Koreans feel ‘gifted’ with that speed, the country has an intense parameters on internet censorship according to the report of the nonprofit Freedom House.

 

Wrapping Up

Perhaps you have just imagined yourself going on a vacation to any of these countries. A faster speed of the internet is one of the factors to consider if the country is getting good economic growth. Providing this privilege to your citizens leaves a good impression of advancement to the world.

Li-Fi Technology Explained

Lifi technology

The latest advanced technology in terms of internet speed and reliable connection has recently been introduced to the world. A counterpart of WiFi or the internet wireless connection, which uses radio signals or waves to transmit data electromagnetically, is called LiFi which stands for Light fidelity. LiFi also transmits data the same way as WiFi does but it uses the ordinary household Light Emitting Diodes (LED) light bulbs. It can boast a speed up to 224 Gbps (gigabits per second). This is really fast!

How it actually works

LiFi is a VLC (Visible Light Communications) system which uses a photo-detector to accept light signals with a processing element that transforms data to a stream able content. The electricity current supplied to a LED light bulb, which serves as a semi-conductor light source, can be converted at high speeds in motions, which is not seen by the human eye.

 

Let me break down the process…

  1. The data is fed to the lightbulb (LED) with a programmed signal processing tech
  2. The data is sent through its beam to the photodiode or photo-detector at rapid speeds
  3. The receiver converts the tiny changes in the LED bulbs into electrical signal
  4. Then the signal is converted to binary data streams (web, video & audio apps)

The obvious disadvantages:

  • LiFi signal cannot pass through walls
  • LED light bulbs should be placed throughout your home
  • The lights will need to still be open even day time, no light no signal
  • It will be hard to implement outside or public places where there is no lightbulbs

But who would not want to enjoy a speed of 224 Gbps?!!

 

The exciting advantages:

  • I have to mention it again that its speed is 224 Gbps (bear with me)
  • The data can be transferred at higher levels with more devices capable of connecting to one another
  • A shorter range makes the connection safer than WiFi because there is less chances of malware interceptions
  • It is reported that embedded light beams off the surface still gives 70 Mbps (still wow!)

Is the World Ready for this?

I have to admit, although I sometimes confess myself as a nerd when it comes to IT, this latest advancement came to my knowledge as a late bloomer. Who would have imagined that we can let the data be transferred through light beams?!

I heard that Dubai started adapting the process and executing the power of LiFi to consumers. And it has been reported that the operation is a success. The rest of the world will pretty soon be presented with LiFi technology. And yup I’m really excited to try and experience the promising speed it has been bragging about.

Imagine what LiFi can do

  • LiFi gives more security that WiFi, and as mentioned, the streaming of data when you are connected to a LiFi is safer from malicious attacks.
  • It can possibly let people have safer night-walks as your city can set enabled LiFi street lights
  • Vehicle head and rear lights could incorporate LiFi enabled LED bulbs which can introduce a car-to-car communication. Imagine what this can easily do when you are on the road. A faster help when you get stranded or more warnings or what-nots ahead on the road.
  • The traffic lights can also be LiFi enabled, so you won’t get bored when a heavy traffic tries to kill your time.
  • WiFi is not enabled under water. With LiFi, an access to internet is now possible even if you are in a submarine.

There are still more possibilities when LiFi becomes part of our daily lives. So buckle up with that imagination, and wait till you find yourself running after light beams.
