There is little doubt that the 5G network – the next-generation wireless standard that promises ultra-fast speeds with almost no latency – is the key technology that will change the rules of the game by 2019. But how many compatible 5G devices will we see this new Year? And how disruptive will they really be?

While most companies will retain the presentations of their phones for the Mobile World Congress event that takes place in Barcelona at the end of February, they expect to see Chinese phone manufacturers like Huawei use the attention they have in Las Vegas to make a wink Meanwhile, chip makers such as Qualcomm, Nvidia and Intel will likely promote their best proposals for 5G, while operators such as Verizon and AT & T will talk about 5G plans during their presentations and speeches that will be offered throughout the week.

Since Verizon said it was the first large telecommunications company to deploy field tests of 5G technology three years ago, the excitement that has generated the promise of this technology continues to grow.

But do not think that the arrival of this network is just about supercharging the connection of your cell phone to the network. Considers that the 5G network is the technology that will allow autonomous vehicles to communicate with each other, or that people can wirelessly transmit virtual reality content in high definition through their VR lenses.

What Is 5g?

It is the next (fifth) generation of cellular technology that promises to greatly improve the speed, coverage and responsiveness of wireless networks. How fast are we talking? Think about 10 to 100 times faster than your current cellular connection, and even faster than anything you can get with a fiber optic cable in your home. (You can download a full season of  Stranger Things  in seconds).

Is It Just About Speed?

No. One of the key advantages is something known as low latency. This term is mentioned a lot. Latency is the response time between when you click on a link or start streaming a video on your phone, send the request to the network, and when the network responds and takes you to the link’s website or starts playing your video.

The waiting time can last about 20 milliseconds with the current networks. If you are wondering how fast 5g network really is compared to other networks you should check internet speed using speedcheck.org. It does not seem to be much, but with 5G, the latency is reduced to 1 millisecond.

That responsiveness is key to things like the reproduction of intense video games in virtual reality or so that a surgeon in New York can control robotic arms that perform an operation in San Francisco. However, the latency is affected by the range of the connection.

How Does It Work?

5G, initially, used a spectrum of super high frequency, which has a shorter range but greater capacity. But, due to range and interference problems, operators are beginning to explore a lower frequency spectrum (the type used in today’s networks) to help carry 5G at greater distances and through walls and other obstacles.

Are There Other Advantages?

Yes. The 5G network is designed to connect to a greater number of devices than the traditional cellular network. For example, 5G will help boost the Internet of Things devices, be it a collar for your dog or a refrigerator.

The 5G network is designed specifically to deal with equipment that is used by industries such as agriculture or ATMs. Beyond speed, it is also designed to work differently in connected products that do not need a constant connection, such as a sensor for a fertilizer. That kind of low-power scanners are designed to run on the same battery for 10 years and still be able to send data.

When Does 5g Arrive?

Verizon will launch the world’s first “5G” service in October. But this is a technicality. The service is not mobile, but a replacement for fixed broadband. An installer has to place special equipment that can pick up the 5G signals and turn them into a Wi-Fi connection at home so other devices can access it.

There is also some debate about whether the Verizon service qualifies as 5G because it does not use the standards that the industry has agreed upon. The company wanted to move forward and used its own technology. Verizon says that speeds, ranging from 300 megabits per second to 1 gigabit per second, make the service eligible to carry the 5G designation. His rivals and even experts from the chip maker Qualcomm deny this claim.

In the report of “ Vulnerabilities in LTE and 5G Networks 2020 ” prepared by the company, the results of the security analyzes carried out in 2018 and 2019 on the networks of 28 operators in Europe, Asia, Africa and Latin America are detailed. In the analysis, they have discovered flaws in the GPRS Tunneling Protocol (GTP) .

GTP Security Flaw: They Can Hack 4G and 5G

GTP is a standard in the IP communications protocol that defines rules when managing traffic on 2G, 3G and 4G networks . It is also part of the GPRS Core Network , as well as its successor, the Evolved Packet Core (EPC) , allowing users to remain connected to the Internet as they move from one site to another.

This protocol has various vulnerabilities affecting both mobile operators and their clients. As a consequence, an attacker can interfere with network equipment and leave an entire city without communications. You can also impersonate users, and use the services with your identity so that the charges reach your bills.

The flaw is that the protocol does not check the actual location of the client, making it very difficult to verify if the traffic is legitimate. Additionally, there is another architecture-level flaw that affects the way client credentials are verified, allowing an attacker to spoof the node acting as the Serving GPRS Support Node (SGSN).

The 5G NSA and SA, Affected by the Failure

The ruling not only allows to act by impersonating another person’s identity, but also elements of the real user’s session can be obtained, such as their phone number. With this, you can redirect traffic to impersonate that of the hacked user.

The attack has been detailed on 4G networks, but since the 5G NSA also uses the EPC as the Core Network, they are also vulnerable to these attacks. All the studied networks are susceptible to a DoS attack against network equipment, which can prevent users from accessing the Internet. This can be really dangerous in a few years when there are a multitude of autonomous devices that depend on the Internet to control themselves, as well as industrial machinery, smart homes or other elements of the IoT.

To mitigate vulnerabilities, Positive Technologies recommends operators to filter IP addresses at the GTP level, in addition to following the GSMA’s security recommendations to analyze traffic in real time and block any activity suspected of being illegitimate. In addition, they must be implemented before the massive deployment of 5G SA, since if you do not run the risk of having long-term vulnerabilities that cannot be fixed in the future because the GTP protocol will continue to be present in the infrastructure.

The post Are You Embarrassed By Your 4G And 5G Can Be Hacked To Charge You For Calls You Don\’t Make Skills? Here’s What To Do appeared first on TodayTechMedia.

Once upon a time, there was 1G. This was back in the 1980s with the accompanying analog device. Next came 2G in the early 1990s, which introduced the digital voice. In the early 2000s, we saw 3G and the rise of the iPhone and mobile data. This brings us to 4G, which most of us use on a daily basis for LTE and mobile broadband.

Consider looking into how to spark a digital transformation in order to better understand the processes, philosophies, and strategies behind what drives this consistent push for better, such as with mobile networks.

1G, 2G, 3G, and 4G all led to 5G, which is designed to provide more connectivity than was ever available before. We’re answering burning questions about the most recent development in mobile networks, the highly controversial and advanced 5G, which is already available to the public. Here’s everything you need to know.

What Is the Technology Behind 5g?

Like 4G LTE, 5G is also OFDM-based (Orthogonal frequency-division multiplexing) and operates based on the same mobile networking principles.

OFDM is s a type of digital transmission and a method of encoding digital data on multiple carrier frequencies, such as with cell phone companies and mobile networks. The new 5G NR (New Radio) air interface further advances OFDM to deliver a much higher degree of flexibility and scalability.

New 5G NR air interface design techniques are also a feature of 5G which will enable broader use of the mobile network, such as in mission-critical communications and connecting the massive IoT.

How Is 5G Better Than 4G?

5G will not only deliver faster, better mobile broadband services compared to 4G LTE, but it will also expand into new service areas such as IoT and cloud computing. 

Here’s a Breakdown of How 5G Compares to 4G:

Faster: Can deliver up to 20 Gigabits-per-second (Gbps) and over 100 Megabits-per-second (Mbps).

Greater capacity: Designed to support a 100 times increase in traffic capacity and network efficiency.

Lower latency: Significantly lower latency to deliver more instantaneous, real-time access.

More unified and more features: Elevates existing services and supports new ones.

Uses spectrum: Gets the most out of every bit of spectrum across a wide array of available bands—from low bands to high bands.

What Industries Is 5G Being Used?

Broadly speaking, 5G is used across three main types of connected services, detailed below. One of the defining characteristics of 5G is that it is designed for the ability to flexibly support future services that are unknown today. This is known as forwarding compatibility.

Enhanced mobile broadband: Can be used to implement new immersive experiences such as VR and AR with faster, more uniform data rates, lower latency, and lower cost-per-bit.

Mission-critical communications: Can enable new services that can transform industries with highly reliable, available, low-latency connections. This includes remote control of critical infrastructure, vehicles, and medical procedures.

Massive IoT: Can seamlessly connect to virtually everything through the ability to scale down in data rates, power, and mobility—providing extremely low-cost connectivity solutions.

Where Is 5G Being Used?

Global operators started launching new 5G networks in early 2019. 5G mobile networks are expected to be available nationwide in many countries by 2020. All major Android phone manufacturers are commercializing 5G phones.

5G has been deployed in 20+ countries and counting, with 5G seeing a much faster rollout and adoption compared with 4G. Consumers are very excited about the high speeds and low latencies 5G brings to the table.

If users wish to use 5G, they would need to upgrade their mobile device to one that has the capacity to handle it. There are several new mobile phones available that are designed to support 5G, and multiple carriers across the world support the 5G wireless network. As the 5G rollout timeline progresses, more smartphones and carrier subscriptions will become available.

Soon, 5G technology and 5G compatible devices will become mainstream.

What Are the Controversies Associated With 5G?

There are several 5G conspiracies out there, many of which peddled by people who associate the recent COVID-19 pandemic with the release and implementation for 5G, due to the timeline. These controversies claim 5G is a hazard to one’s health, can kill birds and plant life, and precipitated COVID-19.

There currently is no scientifically-backed evidence that validates these claims.
