Korean Air Will Not Implement In-Flight Wi-Fi

In-flight Wi-Fi has become a necessity for many people, and especially for business men and women traveling across the globe. Under these circumstances, you would expect Korean Air to go with the flow and strive to offer its passengers access to the Internet.


The reality is different, though; Koreans simply refuse to implement in-flight Wi-Fi on their fleets. So why did they choose to do that? According to Dante Dionne, an innovation technology officer at Korean Air, passengers expect to have in-flight Internet access speeds that are similar with the ones that they are used to on the ground.

Due to the modern infrastructure, the average Internet speed in Korea can reach 100 Mbps, which is about 10 times faster than what could be achieved with existing commercial satellite technologies. Still, I strongly believe that most of the passengers should be happy to check their emails, update their Facebook profiles or simply browse the Internet at slower speeds, rather than being unable to access it at all.


Pasword-Protected Wi-Fi Networks in Europe

The European Court of Justice recently decided that open Wi-Fi providers are not responsible for copyright violations committed by other people. Still, the Court has decided that the providers should protect their open networks using passwords. This way, people who break the law will be easier to track down.


Right now, free Wi-Fi is quite rare in Germany in comparison with other European countries, for example. The explanation is simple: open Wi-Fi providers are liable – indirectly, of course – for the actions of people who connect to their networks.

Everything started a while ago, when a business owner who was offering free Wi-Fi in his shop got a letter from one of Sony’s lawyers. It looks like one of the free Wi-Fi users was sharing Sony’s music, and the company has asked the business owner to pay the lawyer fees.

The Europeans plan to offer free Wi-Fi across the entire continent by 2020.


New Powerful Wi-Fi Technology Hits the Market

What do you do when your Wi-Fi network behaves poorly, disconnecting your devices several times per day, and when the poor Internet speed reminds you of the old dial-up days? You could fix the problem, at least partially, by adding signal repeaters, high gain antennas and high-quality cables to connect them to the router. Fortunately, the Wi-Fi industry is very active, so new solutions that significantly boost speed see the daylight quite often.

802.11ad is a new wireless standard that uses a much higher frequency in comparison with today’s wireless network standards. While 802.11n and 802.11ac operate using 2.4 and 5 GHz frequencies, the new standard operates at 60 GHz. As a direct consequence, the devices are able to handle much more data in comparison with the previous standards.

Due to the ultra-fast speeds, it will be possible to replace cabled connections with 802.11ad routers whenever it is needed, for example.


Believe it or not, TP-Link has already built an 802.11ad router, which is also MU-MIMO capable. Its price is $350, and I think that many enterprise users will be interested in it.

Snapchat Spectacles Are Ready

According to Snapchat CEO Evan Spiegel, Snapchat spectacles are going to be available this fall. But don’t let the fancy name fool you: these are plain video recording sunglasses.

See something you like? A gentle tap on the frames will start the 10 seconds video recording, using a 115-degrees field of view.

The glasses cost $130 and will come in three different colors. Take a look at the video below to see them in action.


Jaybird Freedom Wireless Headphones

Apple’s AirPods may have lured some people, but most gadget reviewers – including myself – were disappointed by them. Let’s pretend that they wouldn’t be that easy to lose, and just concentrate on their sound quality – it’s terrible!

Fortunately, there are several headphones that work without wires and sound much better than Apple’s creation. Jaybird Freedom wireless headphones is a great example of headphones that sound fantastic and aren’t that easy to lose.


In fact, Jaybird’s headphones are built for exercise. Apparently, there are the perfect devices for cyclists and even volleyball players, which are known to move their bodies quite a bit while they’re playing.

Just like Apple’s headphones, Jaybird’s headphones make use of a Bluetooth connection and provide about five hours of music time. But they look – and most of all, sound – so much better!


Microsoft and Raspberry Pi

Microsoft’s Internet of Things Grove Kit will help us develop cool gadgets (smart devices, robots, etc) using the Raspberry Pi 3 computer. The kit, which will soon be available at Digi-Key Electronics, will set you back quite a bit – it’s $155.

It may sound expensive, considering the fact that the third generation of the Raspberry board can be purchased for only $35, but wait until you see its content:

– 5-inch HDMI touch display with a resolution of 800×480 pixels (WVGA);

– RGB LED expansion board;

– weather sensor;

– light sensor;

– sound sensor;

– buzzer;

– actuators;

– connector cables;

– more!


The highlight is definitely the 5-inch HDMI touch display. I can only imagine how many cool projects we can build, and then run their output on this monitor!

Of course, people who are interested in building robots will need a few more parts – servos, for example.

Microsoft wants to put Windows 10 on as many devices as possible, and it’s encouraging to know that its OS can run decently even on a Raspberry Pi computer.
