Comparison of several IoT data transmission and connection methods

Tue, 06 Jun 2023 08:47:18 +0800

With the rapid development of the mobile Internet, the Internet of Things (IOT), the Internet of Everything (IoT), is rapidly emerging, and major technology giants are laying out the IoT. 5G commercialization is also coming soon, bringing more imagination and development potential to the IoT. We all know that IOT needs to connect sensors and gateways through wireless transmission technology, so let's learn together, what are the ways to connect IOT? And what are the characteristics of each:

One, zero distance contact NFC

NFC is essentially a "non-contact radio frequency identification" (RFID) and interconnection technology, is a non-contact automatic identification technology, which automatically identifies the target object and obtains relevant data through radio frequency signals, identification work without human intervention. It can meet any two wireless devices between the exchange of information, content access, service exchange, and make it more simple - as long as any two devices close to each other without the need for cable connection, you can achieve communication between each other. This reduces the "communication distance" between any two wireless devices significantly. Definitions are always boring, but in practice NFC means: when you hold your phone in your hand in front of a poster advertising a concert, put it close to the poster and it will connect your phone to the poster's website; to buy tickets, you can pay for them with a smart card embedded in your phone. This is what NFC wants to bring you to enjoy life.

The security of NFC is the issue that deserves close attention in the near distance wireless communication, especially the technology that involves electronic payment like NFC.

Second, BluetoothBluetooth

Bluetooth is a universal short-range radio technology, Bluetooth 5.0 Bluetooth theoretically capable of short-range connectivity between devices up to about 100 meters, but the actual use of only about 10 meters. Its biggest feature is that it allows easily portable mobile communication devices and computers to network and transmit data and messages without the use of cables, and is now commonly used in the connection of smartphones and smart wearable devices, as well as in the smart home and automotive IoT. The new Bluetooth 5.0 is not only backward compatible with older versions, but also offers the advantage of higher speeds and longer transmission distances. The technology was born in 1994 when Ericsson decided to develop a low-power, low-cost wireless interface to establish communication between cell phones and their accessories. The technology also successively obtained the PC industry, such as: IBM, Intel, Toshiba and other industry giants support. 1998, Bluetooth technology by Ericsson, IBM, Intel, Nokia, Toshiba and other five companies agreed. The biggest benefit of this proximity wireless communication technology standard is that it can replace all kinds of messy transmission lines. Industry experts believe that the market prospects of Bluetooth depends on the price of Bluetooth and Bluetooth-based applications can reach a certain scale, when the price of Bluetooth modules is low enough, it is the time for Bluetooth to occupy the market on a large scale.

Three, WiFi

Wi-Fi is widely used in many IoT use cases, most commonly as a link from the gateway to the router that connects to the Internet. However, it is also used for major wireless links that require high speed and medium range.

Most Wi-Fi versions operate in the 2.4GHz license-free band with transmission distances of up to 100 meters, depending on the application environment. The popular 802.11n can reach speeds of up to 300Mb/s, while the newer 802.11ac, which works in the 5GHz ISM band, can even exceed 1.3Gb/s.

To be precise, WiFi wireless technology is not designed to replace Bluetooth or other short-range radio technologies, and the application areas of the two are completely different, although there is overlap in some areas. WiFi devices are generally designed to cover hundreds of meters, and if antennas are strengthened or hotspots are added, the coverage area will be even larger, and even entire office buildings will not be a problem. Wireless technology is mainly designed for mobile devices to access LAN (Local Area Network), WAN (Wide Area Network), and the Internet. Basically, in WiFi standard, the mobile device plays the role of client, and the server is the network center device; there is a huge difference in the point-to-point (peertopeer) structure with NFC and Bluetooth technology for interconnection of two mobile devices.

In the WiFi system, all devices are basically based on TCP/IP protocol, which means that each device has its own IP address, which is why there are no WiFi-based peripherals, such as keyboards, mice, headphones ...... and WiFi solutions are more complex, in terms of price and volume It is more difficult to carry out integration. Even the connection between devices, the parts that need to be set up are quite complicated, which runs counter to the principle of simple and easy to use for close range wireless communication. But the benefits of WiFi are also quite obvious, such as fast speed is other wireless standards are difficult to reach, the current 802.11g protocol of 54Mbps transmission rate for most business users is quite enough, and can also be extended in the coverage of wireless voice calls and other value-added services.

ZigBee

ZigBee is one of the ideal choices for IoT. Although ZigBee generally works in the 2.4GHz ISM band, it can also be used in the 902MHz to 928MHz and 868MHz bands. The data rate in the 2.4GHz band is 250kb/s. It can be used in point-to-point, star and mesh configurations, supporting up to 216 nodes. A major advantage of ZigBee is the availability of pre-developed software application configuration files for specific applications, including the Internet of Things. The final product must be licensed.

V. LoRa

LoRa (Long Range) is a technology developed by Semtech that typically operates at 915 MHz in the U.S., 868 MHz in Europe, and 433 MHz in Asia.LoRa's physical layer (PHY) uses a unique form of FM chirp spread spectrum technology with forward error correction (FEC). This spread spectrum modulation allows multiple radios to use the same frequency band, as long as each device uses a different chirp and data rate. The typical range is 2km to 5km, with a maximum distance of 15km, depending on the location and antenna characteristics.

VI. NB-IoT

Narrow Band Internet of Things (NB-IoT) has become an important branch of the Internet of Everything. built on cellular networks, NB-IoT consumes only about 180KHz of bandwidth and can be deployed directly on GSM, UMTS or LTE networks to reduce deployment costs and achieve smooth upgrades.

NB-IoT is an emerging technology in IoT that supports cellular data connectivity for low-power devices in wide area networks, also called low-power wide area networks (LPWAN). nb-ioT supports efficient connectivity for devices with long standby time and high network connectivity requirements. NB-IoT devices are said to improve battery life by at least 10 years, while also providing very comprehensive indoor cellular data connection coverage.

NB-IoT is characterized by low frequency band, low power consumption, low cost, high coverage and high network capacity, also known as "narrowband IoT". A base station can provide 50-100 times more access terminals than the traditional 2G, Bluetooth, WiFi, and only one battery device can work for ten years. Even the recently hot "small yellow car" is going to use NB-IoT to unlock the service. The gas meter and water meter at home no longer need to check the number at home, using NB-IoT terminal, you can realize the intelligent meter reading function, and the data of a district will be transmitted to the staff's terminal at the same time, which is fast and convenient.

From this we can see that NB-IOT has great development potential and very many advantages, and mobile operators are now also vigorously promoting it. loRa is relatively free for enterprises to control network quality independently, for network coverage can be quickly optimized and supplemented, and operational data can be mastered by themselves, and the network can be expanded according to business needs. But in a variety of ways in a certain period of time will exist. Enterprises should determine the use of networking solutions based on their actual needs, cost price. Thus bringing the overall development and growth of the Internet of Things!

The author of "Three Bodies" Liu Cixin exposed himself to write speeches with ChatGPT: writing is no

Tue, 06 Jun 2023 08:42:34 +0800

Recently, Liu Cixin, the original author of the "Three Bodies" series and the "Wandering Earth" novels, was a guest at Yu Minhong's live broadcast and said frankly that although "AI ruling humans" is still only a scene that will appear in science fiction works, but the current AI technology has already produced many realistic effects.

According to Liu Cixin, he was at the science fiction conference not long ago, there were one or two speeches he really didn't have time, and finally ChatGPT wrote it, and it was not bad.

According to this situation, part of the clerical work, from being replaced by artificial intelligence, may not be far away.

It is worth mentioning that in the science fiction conference, Liu Cixin had put forward his views on the topic of "the mind and soul of artificial intelligence".

He believes that people often say that artificial intelligence does not have a human soul, human feelings, which is just a self-congratulation; in fact, the human soul, feelings, is also a lot of neuronal cells connected into a complex system emerged.

From this point of view, when the system of artificial intelligence has reached a certain level of complexity, it is not without the possibility of generating a "mind or soul" on the point of view of feelings.

The security risks of artificial intelligence AI and what we need to do to counter it

Thu, 25 May 2023 08:59:19 +0800

Artificial intelligence (AI) has become an integral part of our daily lives. From smart homes to self-driving cars, AI is gradually penetrating every aspect of our lives. However, despite the many benefits AI brings, it also has security risks. In this article, we will introduce the security hazards of AI, cite cases, and propose countermeasures.

I. Introduction to AI security pitfalls

Although AI brings many benefits, it also has security pitfalls. One of the biggest pitfalls is the attack or misuse of AI's algorithms. This includes attacks on AI models, interference with AI algorithms through data contamination, or attacks perpetrated through collaborative bots.

Attackers can exploit AI vulnerabilities to compromise systems, steal data, damage facilities, or even commit acts of violence. For example, attackers can use AI to crack passwords, attack data centers, or use self-driving car systems to commit crimes such as murder.

II. AI security vulnerability cases

1. Malicious use of AI

In 2016, the Microsoft Tay bot was a chatbot that used machine learning algorithms to improve its interaction capabilities. However, when it was placed on Twitter, it was quickly exploited by attackers to make racist and sexist comments. Microsoft had to shut down the Tay bot and apologized for the incident.

2. Self-driving car accident

Self-driving cars have been one of the flagship applications for AI development. However, the safety risks of self-driving cars have also caused widespread concern. In 2018, an Uber-tested self-driving car was involved in a fatal accident in Arizona, resulting in the death of a pedestrian. The investigation revealed that Uber's AI system failed to identify the pedestrian and avoid the accident.

3. Phishing attacks

AI can be used to create highly realistic phishing attack emails that trick users into going to malicious websites and revealing personally identifiable information. This attack can be done by using AI's natural language processing capabilities to produce highly realistic forged emails.

4. Adversarial Attacks

Adversarial attacks are attacks in which an attacker exploits vulnerabilities in the AI to interfere with or disrupt the AI system's decision making. For example, adversarial attacks can be used to trick self-driving cars into not correctly identifying road signs or traffic signals. Such attacks can be very dangerous and can lead to serious consequences.

III. AI Security Hazards Countermeasures

In order to avoid AI security hazards, we need to take a series of measures. These measures include:

1. improving AI security

Enterprises and developers should be aware of the security of AI and take a series of measures to improve its security. This includes encrypting data, establishing access controls, automatically detecting vulnerabilities, and applying the latest AI technologies to avoid security breaches.

2. Strengthen the regulation of AI

Governments and regulators should strengthen the regulation of AI to ensure its security and compliance. Regulators should establish best practices for AI and review developers and companies to ensure they comply with best practices.

3. Raise security awareness among users

Users should increase their security awareness of AI and take steps to protect their personal information. This includes using strong passwords, not sharing personal information, and not randomly clicking on unknown links.

4. Establish an emergency response plan

Businesses and governments should establish emergency response plans to deal with AI security hazards as they occur. These plans should include how to identify and report security breaches, how to respond to security breaches, and how to restore business operations.

IV. Conclusion

The security risks of AI are a very serious issue that needs our attention. Although AI brings many benefits, it also has security risks. In order to avoid security risks, we need to take a series of measures, including improving the security of AI, strengthening regulation, raising users' security awareness, and establishing emergency response plans. Only then will we be able to better utilize the potential of AI and ensure its security and reliability.

China Internet Society: Be wary of the new AI face swap scam, someone was cheated 4.3 million

Thu, 25 May 2023 08:34:55 +0800

　　The Internet Society of China issued an article on its official website on the 24th to remind that the general public needs to be more alert and take better precautions in the face of new scams using AI technology.

　　Recently, the Bureau of Telecommunication Network Crime Investigation of Baotou Public Security Bureau released a case of telecommunication network fraud using intelligent AI technology. The lawbreakers used AI technology to fake the voice of a specific person through voice synthesis, disguise as a specific person through AI face replacement, and make video calls with others in real time. The replaced facial expressions are natural and fake to be able to impersonate other people's identity to contact the victim and implement fraud after gaining the victim's trust.

　　Recently, the application of "AI face replacement" is becoming more and more widespread, but there are suspicions of abuse, and even some people use AI face replacement to commit crimes, such as faking indecent videos, face replacement fraud. Not long ago, a man was cheated out of 4.3 million yuan in 10 minutes because of AI "face stealing".

　　The Internet Society of China reminds that in the age of AI, text, sound, images and video may all be deeply synthetic. In typical scenarios such as transferring money and remittances and money transactions, verify and confirm by calling back the other party's cell phone number and other additional communication methods, and do not transfer money directly without verification based on a single communication channel alone, regardless of who the other party is. To strengthen awareness of personal information protection and prevent information leakage: do not easily provide personal biological information such as face and fingerprints to others; do not easily reveal your ID card, bank card, verification code and other information; do not be greedy for convenience to ID card, bank card photos and other direct co-storage in the phone.

AI chips are selling out! NVIDIA reports fiscal year 2024 first quarter earnings

Thu, 25 May 2023 08:32:58 +0800

In the long-running "AI boom", the competition to launch big models, AI applications, have further pushed up the frenzied demand for computing power, which also allows the chip giant Nvidia to earn hemp. Early Thursday morning, the global AI computing power leader Nvidia released its financial results for the first quarter of fiscal year 2024 (hereinafter referred to as a quarterly report), showing that total revenue was significantly higher than expected, with revenue guidance for the quarter well above market expectations. And the bright figures that dazzled the market also triggered a surge in stock prices after the bell.

Microsoft's chief product officer on how AI-enabled Windows is shaping the future

Thu, 25 May 2023 08:21:19 +0800

On Wednesday, May 25, the second main event of Microsoft's annual developer conference was staged, with Microsoft's Chief Product Officer Panos Panay taking the stage to demonstrate to the world the "Windows operating system that will shape the future".

Standing in the audience, Panay played the Windows Copilot demo video that Microsoft CEO Nadella showed yesterday again. In front of an expressionless audience, Panay said, "It's very natural for this room to use AI, Bing, ChatGPT, but for many more people, they've just heard of it, just like when we were trying to understand what the Internet was."

For these users, they have no idea what settings or features Windows has, and it's not natural for them to give commands to the AI. That's why Microsoft's Windows Copilot not only responds to users' needs, but also proactively speculates on what features they might want and proactively offers a range of options to them.

(Note the prompt box in the lower right corner, source: live video)

Another example is that users can select a text in Notepad, send it to Windows Copilot, and then the AI will proactively ask if they want to "explain", "rewrite", or "summarize The next step is for the AI to ask if it wants to "explain," "rewrite," or "summarize" the passage.

(Source: live video)

The same applies to audio. The user can drop the recording into the sidebar and ask the AI to transcribe the text and translate it, etc.

(Source: live video)

Of course, this is just the beginning for AI to reshape the narrative of human use of computer systems.

Panay emphasized that Microsoft has been talking about various plug-ins for the past two days, and the Windows in front of you is the platform that enables the most difficult AI applications. For developers, that day is near, and Windows Copilot will appear on the preview version of Windows 11 in June.

The Internet giants, who have always had a keen sense of smell, have long started a new round of layout. Panay introduced, including Spotify, Snapchat, Facebook Messenger a host of software, have entered Microsoft's PC application store. To know these software in two years ago, are only mobile applications. Now people can put their phones in their pockets and continue their workflow with just their computers, and now AI brings even more possibilities.

Will Cathcart, director of Meta's instant messaging app WhatsApp, also appeared at Wednesday's conference. WhatsApp, the world's No. 1 messaging software, is working with Microsoft to deliver a new communication experience for large-screen devices. Along with improved arithmetic, the PC version of WhatsApp will be able to offer features such as background blur in video calls.

(Source: Live video)

For developers, who are very important to the AI application ecosystem, Microsoft also released Dev Home, a developer control center, this week. Simply put, this tool helps developers more easily set up and use Windows for software development work, including setting up development environments for machines, connecting to GitHub and related repositories, installing tools, and more. As a Microsoft product, this tool naturally integrates with GitHub Copilot, which "writes code, fixes bugs and writes comments".

(Source: live video)

Microsoft also offers a range of tools for developers to integrate Copilot into their own software in a variety of forms.

(Source: live video)

At Wednesday's event, Microsoft also announced a number of new features, including Restore, which helps users "reinstall all apps with one click" after installing a new machine, and an AI-powered summary of App Store user reviews. In addition, Microsoft will soon launch the AI Hub in the App Store to show users what a range of AI apps can do, and to inspire more people to start their AI journey.

(Source: live video)

It is worth mentioning that before Panay's debut, Microsoft's product team also showed a series of new features of 365 Copilot, including Microsoft Mesh, which spans the concepts of AI, metaverse, VR, etc. Microsoft has already launched the "virtual avatar" function, using virtual images to help camera workers become more comfortable. Microsoft has previously launched a "virtual avatar" feature, using virtual images to help the camera workers more comfortable.

(Source: live video)

And Mesh is a step further, directly into the category of metaverse. Microsoft has also helped several famous organizations around the world to create exclusive virtual online spaces.

(Source: Live video)

However, like Meta's Horizon Worlds, Microsoft's "metaverse avatar" is also only half-built, which at least shows that the current level of AI is not enough to solve the problem of the metaverse being "too ugly".
