You’ve probably already heard of 5G. Some, in fact, must already be tired of hearing about it. Do you really understand the evolution that 5G will bring to our everyday life, though? The technological transformation that it can provide? Well, my goal with this article is to present the most relevant features of 5G.

A 5G network is a cellular system, as are analogue systems, 2G (GSM), 3G (WCDMA) and 4G (LTE). But, its emergence, at first, does not have as its main goal of connecting mobile phones or allowing people to communicate faster. 4G already meets this need well.

The main idea of 5G is to connect things. What things? Any kind of thing that creativity and human need requires. That is, 5G will take the development of the Internet of Things (IoT) to an entirely new level.

So, with 5G, we will be able to connect, for example, any type of appliance that exists in a house, such as a microwave oven, TV, air conditioning, refrigerator, washing machine and even doors, windows and monitoring cameras. It will be possible to control and interact with a house at any time of the day. It will be up to each user to decide and program the autonomy of each utensil, according to their needs.

Some benefits of the 5G system are:

  • Faster data exchange;
  • Much lower latency;
  • Increased number of devices that can be connected to a single cell tower.

Firstly, let’s talk about speed. The 5G system promises a theoretical speed of approximately 10 Gb/s. That’s a lot. Currently, the 4G system has a theoretical capacity of 300 Mb/s. That means that the 5G system will be approximately 34x faster. Those numbers are the download speed rates.

The upload speed will also increase. However, upload speed rates will not be updated in the same proportion as the download speed, due to device battery limitations. It is not possible to specify the value of upload speeds on 5G systems yet, since we do not have any devices on the market, but it should also increase considerably, compared to the speed rates of the 4G system.

Latency is the delay in time between a request and its response. Imagine that a person in front of a screen and a button. This person is instructed to press the button to end the activity whenever the image of a bird appears on the screen.

The activity starts and random images begin to quickly appear on the screen. The delay in time that the person takes to identify the image of the bird within the sequence of images and trigger the button is latency.

The current latency of 4G networks is approximately 50 milliseconds. This value allows us to make video calls, for example. However, we still notice a delay between questions and answers of the callers. 5G promises to end this and do much more — the promised latency for the 5G system is 1 millisecond, that is, much lower than that of 4G networks.

Thus, one of the many possibilities brought on by the implementation of 5G would be the autonomous car. The entire transportation system would be interconnected in a 5G network and its security can only be guaranteed with a very low latency. This low latency is essential in order to have a response time similar (or even faster) than the human reflex.

A human driver, concentrated in traffic, knows the right time to brake and accelerate their vehicle. The driver knows that they need to stop at intersections and red traffic lights. An autonomous car needs to have this “intelligence”, and, most importantly, the same reaction time.

Thus, in a 5G system, an autonomous car brake warning will be fast enough to avoid a collision. This would be the “real-time” response, similar to the human reflex. However, latency in 5G is faster than the human reflex. Therefore, an autonomous car will be theoretically safer than a human driver.

The 5G system also promises a greater number of simultaneous connections per cell tower. In the 4G system, we have approximately 100 thousand connections per square kilometer. With 5G, we will have 1 million connections in the same area. Thanks to this significant increase in connections, the 5G system will be known as the system that managed to connect “things “(understanding “things” as any electronic equipment) to the Internet.

With this increase in the number of connections, it will be possible to connect everything around us: appliances, doors, windows, cars, motorcycles, traffic lights, sensors on streets and highways, light poles, security cameras, electricity and water meters, among many other things. We’ll be able to have a “living” and smart city, where interaction would be complete and instant and work 24/7.

This city would be alive because everything would be connected. Smart, because all “things” would have microprocessors with software. Instant, because of the very low latency. Your car would “talk” with other cars, with the streets and roads and calculate the best route to any destination. It could warn your gates when it was coming so that they would automatically open. You could program your residence to open the windows if it is sunny, close them if it looks like it will rain. A doctor could operate on a patient remotely, through mechanical arms.

The possibilities are endless. 5G will be a real game-changer in the society we live in today. Surely, the changes will not be instant, because there is a whole industry aimed at profit. However, the deployment of the 5G system is definitely the first step towards these changes.

we are constantly evolving, therefore, we are already studying the technology that enables the 5G system to exist.

Currently, we have equipment capable of analyzing the spectrum range that will be used in the 5G system. We have a spectrum analyzer (FSW85 from Rohde Schwarz) that reaches up to 85GHz, able to analyze the 5G NR Sub 6GHz and also the 5G range that operates above 24GHz mmWave (millimetre waves).

The past two years have demonstrated biometric technology’s positive influence on our daily lives. Biometric applications in healthcare, finance, cloud computing, and online applications have easily integrated technology into our everyday life. As with any other digital technology, it is impossible to precisely foresee the future of biometric technology, which has become an integral part of the modern digital ecosystem. Nonetheless, adequate evidence indicates that the biometric industry will continue to expand rapidly, said experts from Securiport Sierra Leone. Securiport provides cutting-edge border management technologies through solutions-based services at no cost to clients. Their mission is to assist governments in preventing criminals from crossing borders undetected and in uncovering unlawful transnational activities.


With solutions currently in place across dozens of countries around the world, and a dedicated team of professionals developing innovative tools to respond to ever-changing environments.

According to the most recent report by EMERGING Research, the biometric industry attained revenue of US$44 billion in 2021 and is forecasted to expand at a CAGR of 14.8% between 2022 and 2027. Let’s examine some of the most innovative technological innovations shaping the future.

Here are the top six biometric technology developments that organizations should look out for in 2022:

#1 Cybercrimes Adapt to Artificial Intelligence

As Machine Learning (ML) and Artificial Intelligence (AI) capabilities grow more prevalent in our daily lives, cybercriminals have gotten more sophisticated in detecting target systems and employing tech-driven tools. As artificial intelligence refines attackers’ strategies, they can now attack systems ruthlessly and consistently, concentrating on their weak points. Deepfake is an example of an AI-based cyberattack that exploits identification systems by imitating the facial characteristics of victims. Therefore, the rate of evolution of these complex risks will continue to increase in 2022 and beyond.

#2 Trustworthy Identity Verification Systems

Sharing economy platforms, such as Uber, Airbnb, and a variety of other businesses that connect people via P2P services, are continuously searching for new strategies to establish their reputation. Consequently, this sector has increased the use of identity authentication with non-shareable credentials. Using non-shareable credentials allows companies to offer services that make them more trustworthy and improve the customer experience.

#3 Non-Transferable Credentials

Restricting authentication to a specific person is a pressing problem for many businesses, from banking institutions to school systems to the sharing economy. It’s difficult for ride-sharing companies, for example, to guarantee that drivers and customers are who they say they are.

Therefore, it’s challenging for businesses to maintain a check and balance on the driver to see if registered entities are executing their tasks. Since credentials and devices can be freely traded or taken by force, biometric authentication will lead the way in this space.

#4 Electronic Identification, Authentication, and Trust Services

The Electronic Identification, Authentication, and Trust Services (eIDAS) regulations will redefine how companies related with their customers in 2022. eIDAS is an automated system that lets businesses verify their clients’ identities and government-issued documents. eIDAS will increase inclusion by allowing individuals to interact online, reducing the environmental footprint of travel, improving efficiency, and providing a cost-effective choice to encourage international commerce for economic growth.

People and businesses in Europe expect to see much work done in 2022 and beyond to ensure customer confidence, verify the credibility of online transactions, and secure access to services.

#5 Unstaffed Stores

The concept of unstaffed stores emerged after the coronavirus pandemic destabilized the global order – and has never looked back since. Before entering these businesses, consumers are asked to download a smartphone application that must be scanned. Furthermore, AI-backed facial biometric recognition devices are also installed to verify clients.

A series of digital cameras are also deployed to monitor customers and record their activities, including the things they carry in their bags. Numerous pilot stores without employees have opened but are still in the testing phase. However, 2022 seems to be the year when such stores become prevalent.

#6 NFC-Powered Travel Solutions

Global transit networks use contactless technologies to promote a safer travel environment for passengers on buses, trains, and airports. Due to COVID-19, public transportation and activities have become a possible risk for customers. Service providers are aware that they must overcome new challenges to sustain and build ridership and maintain and establish confidence in their services.

Businesses employ biometric technology solutions to provide a safer travel environment, from mask compliance to cleaning initiatives. In addition, NFC-based payments allow users to tap their chip-based identification card on the NFC-powered device installed at the terminal.

Conclusion

Traditional passwords have long been the weak point for many security systems. Fortunately, modern cybersecurity concentrates on eliminating the risks associated with this powerful security solution. Biometrics address this issue by connecting proof of identity to our bodies and behavioral patterns.

Biometric technology is quickly replacing the conventional ways of identity authentication, which have many flaws and are easy to hack. Biometrics strikes the perfect balance between security and ease of use.

Even if fingerprint scanners are integrated into smartphones and many computers, there is still potential for innovation in the authentication and payment applications of the technology. Banks, tech companies, and payment companies are trying new methods of identifying customers based on their unique physical attributes. The objective is to enhance security while streamlining customer onboarding and verification.

Snowflake Offers Weak Product Revenue Guidance, Stock Reverses Up
Want create site? Find Free WordPress Themes and plugins.

Snowflake (SNOW) reported third-quarter earnings that met expectations while revenue topped Wall Street targets. The enterprise software maker’s product revenue guidance came in below expectations. SNOW stock initially tumbled, then reversed up.

The company reported third quarter earnings after the market close on Wednesday. For full-year fiscal 2024, which starts with the April 2023 quarter, Snowflake said it expects product revenue growth of 47%, below consensus estimates of 52%.

Because Snowflake’s business model is consumption-based rather than subscription-based, bearish investors have raised concerns over a possible U.S. recession curbing demand. Snowflake revenue is tied to how much data its customers crunch and store on cloud computing platforms.

For the quarter ending Oct. 31, Snowflake said it lost 63 cents per share versus a 51-cent loss a year earlier. Analysts polled by FactSet expected Snowflake to report a loss of 63 cents a share.

The company reports results using generally accepted accounting principles, or GAAP. Snowflake does not break out adjusted earnings in its releases.

Third-quarter revenue climbed 67% to $557 million, the software maker said. Analysts had predicted revenue of $539.4 million.

SNOW Stock: Revenue Outlook Misses

The Snowflake earnings report also said product revenue rose 67% to $522.8 million vs. estimates of $505.2 million.

At UBS, analyst Karl Keirstead said in a report: ”  To be clear, 67% revenue growth in Q3 and the guide for 47% growth in fiscal 2024 is very impressive in this macro (economy) and certainly doesn’t speak to anything ‘broken’ with Snowflake. That said, investor expectations were running high into this print.”

For the current quarter ending in January, Snowflake expects product revenue of $537.5 million at the midpoint of its outlook. Analysts had expected $549.2 million.

SNOW stock initially fell on the earnings release. But Snowflake stock reversed up 2.1% to near 146 in morning trading on the stock market today.

Snowflake stock was down 57% for 2022 heading into the earnings report.

Snowflake sells data analytics and management tools that run on cloud-computing platforms such as Amazon Web Services, part of Amazon.com (AMZN).

Amid the bear market in software growth stocks, the software stock has a Relative Strength Rating of 17 out of a best-possible 99, according to IBD Stock Checkup.

He also said the Chinese path to modernization provides an alternative way for countries to achieve rapid development while preserving their independence.

“China is committed to be a builder of world peace, a contributor to global development and a defender of the international order. It is also a key participant of, and a contributor to, global development cooperation. From a global strategic perspective, stronger South-South cooperation will help promote democracy in international relations,” Qu said.

Hosted by the China Watch Institute of China Daily and the Technology and Management Center for Development, which is part of the University of Oxford, the forum themed “South-South Cooperation in Science, Technology and Innovation” was held online on Friday.

Qu said the purpose of holding this forum is to share the experience of sustainable development and build consensus for promoting South-South cooperation, thus contributing to the building of a community with a shared future for mankind.

He called for efforts to enhance South-North cooperation and deepen South-South cooperation, and align the Global Development Initiative with the existing development and cooperation strategies of participating countries to generate greater synergy in global development.
