fiber vs adsl

Fiber or ADSL? Which technology is better?

Why is fiber faster than ADSL? And above all, what about choosing between fiber or ADSL when you have a choice?

The answers may not be obvious, and we explain why below.

Fiber or ADSL: a story of throughput above all

We could spend hours explaining technically what makes ADSL different from the fiber. But the easiest way to find out which fiber or ADSL is the best is to launch an Internet speed test. The speed exceeds 110 Mb/s on a fiber connection, its lower limit, i.e., a download speed of about 12.5 Mb/s. A download can go up to 1 Gb/s (or 125 MB/s in the download).

On the ADSL side, it all depends on your location. With luck, you can get a maximum of around 80 Mb/s (or 10 Mb/s in the download), because its line must be eligible for VDSL2 technology and therefore be close (less than 3.5 km) to a DSLAM (among other constraints). The user is content with a “simple” ADSL connection without VDSL technology with a maximum speed of 20 Mb/s (or 2.5 Mb/s in the download), which is now considered very weak.

What is the advantage of fiber over ADSL?

Attenuation is a defect that does not concern the fiber – or much less – since the signal strength is reflected on a glass or plastic surface inside a cable. The attenuation is almost non-existent and, above all, the data transmission speed is much faster.

The advantage of fiber over ADSL is, of course, its speed, wherever you are. However, it has one major flaw today: it requires the line to be built to the user’s home (this is called FTTH fiber, or Fiber to the Home). In other words, it is necessary for a technician to come to your home to drill through your walls or floors and physically pull it to your Internet box. It is not always possible or, at least, not still possible quickly.

Is it better to use ADSL or FTTLA fiber?

But regarding the download, it is often much faster (up to 10 or 20 times) than a traditional ADSL line. While waiting for very high-speed connections to become widespread throughout France, it very often happens that different operators only offer ADSL or FTTLA fiber offers, without any other alternative. In this case, there is no hesitation, regarding throughput, it is the FTTLA fiber that should be used. The subscription sometimes costs a few more euros, but it is to have a much higher performance.

Epic Games: millions of Fortnite players exposed to a vulnerability

A flaw in Fortnite that was discovered by researchers from a security solutions provider allowed hackers to take control of a player’s account, and to access his confidential data. Corrected since then by Epic Games, this breach made it possible to use the recorded credit card and listen to the games without the players’ knowledge.

Thanks to its team of researchers, security systems publisher Check Point Software Technologies discovered a flaw in the Fortnite video game that potentially affected all registered accounts, 200 million players worldwide. The main version of the game, called Fortnite Battle Royale, consists of a player-to-player battle, with games involving up to 100 players at a time, organized in teams of two or four, or solo. They must scan the map for weapons, objects, and resources. The last team still alive wins the game.

Players can buy V-Bucks, the virtual money of the game, by spending real cash after recording their credit card information, and most often, their parents’ credit card information. These purchases offer no strategic advantage and are mainly used to obtain cosmetic improvements. Despite this, accounts can be resold on specific sites for several hundred dollars, making them a target of choice for hackers. The most common scams use fake sites that promise players free or discounted V-Bucks, encouraging them to identify themselves and therefore give the website their password.

Hacking with a single click

The discovery of the Israeli research team is much more sophisticated and consists of a flaw in the identification through another sub-domain of the publisher Epic Games. The website, dedicated to the results of Unreal Tournament 2004, contained a SQL vulnerability. The team took advantage of this opportunity to steal the user’s OAuth identification token, which allows them to identify themselves with a third-party account, such as Facebook, Xbox Live, Nintendo, Google or PlayStation Network. This token is sufficient to access the player’s account on the site. The attack takes the form of a link, for example by promising promotional V-Bucks. Just clicking on the link allows the pirate to steal the token, no further action is required.

The researchers’ demonstration shows that they were able to access the entire account and even buy virtual currency with the registered credit card. However, the intrusion is not limited to the personal information on the site. By logging into the account, a potential hacker could have followed the discussions in the game, including the audio talks. Any intruder would not only have been able to hear the player talking but also conversations from other people in the background, near the microphone.

The vulnerability is already fixed

Even if fixed with a patch, the fact remains that this breach, not exploited in its current state since discovered by researchers, could encourage pirates to dig deeper into the game’s protections to exploit other vulnerabilities. And this time, it is not sure that the publisher will be informed.

CES 2019: 5 techno trends to monitor

Las Vegas’ CES is the annual meeting place for high-tech innovations.

So what technological trends can we expect from this 2019 edition? Here are the 5 biggest trends that will be at the heart of the announcements and discussions of this 52nd edition.

5G

If the 5G has become the spotlight of CES and the Mobile World Congress, the first wave focused on two major markets: the IoT and the Internet at home, for access without fiber and cable. While 2019 saw the announcement of the first 5G smartphones, announcements from major manufacturers and start-ups of connected objects should also go in this direction with the integration of 5g technology directly into devices. It is right in sectors as diverse as the smart home, health and the connected car.

Immersive reality

Mixed reality, augmented reality and virtual reality have also become recurrent trends in these areas. But this 2019 edition should be marked by the generalization of these technologies. This 52nd edition of the Las Vegas show will also demonstrate the installation of augmented reality in everyday life, whether in the world of health, education, and training, but also in sport.

Voice-activated devices

If Amazon Alexa at these 2017 and google assistant the following year have made the buzz, these 2019 should see a proliferation of these voice assistants and newcomers in multiple devices, such as televisions, connected mirrors, cars and even more surprising products like switches.

Connected and autonomous cars

In two years, the CES has also become the new car fair. This 2019 edition will not contradict this trend with the presentation of new technologies embedded and connected in vehicles. All this coupled with new customization solutions based on the preferences and habits of drivers and passengers, based on AI and in particular deep learning.

And while demonstrations of autonomous vehicles, particularly regarding delivery, will animate the show, another trend will illustrate this 2019: the integration of connected cars into new sharing solutions, with the rise of self-service systems, new parking, and multimodal platforms and, in fact, announcements of partnerships with actors from other types of transport, urban centres…

Resilience and digital trust

Finally, and this year it is a trend that is emerging: resilience. Faced with facebook-type scandals or various cyber attacks, expectations regarding the security of personal or non-personal data and digital trust are growing.

In such a context, the blockchain is an interesting example that should be illustrated in 2019 by solutions and use cases that go beyond cryptocurrencies. More and more local solutions, such as the award-winning sniper voice platform or e-privacy solutions, should also be presented.
