We are a traditional industry, but we have an unconventional heart. Enterprise Users are located both in China and abroad. In the face of the industry, it is necessary to build an industry-level (BIG) data platform. When talking about big data platforms, we often think of Hadoop, Spark, Nosql, distributed, etc. I c
Low-Power Wi-Fi transmission standard HaLow is designed for Iot
In most homes, Wi-Fi has become a very important connection method, but many smart home products have never used Wi-Fi connection methods. Why?
One of the biggest problems that many companies do not want their products to use Wi-Fi connections is that Wi-Fi consumes too much power, this is not enough for smart home products that are small, inexpensive, or that require one-time charging f
Ubuntu has revealed to the outside that their newest idea of Iot is to make Linux the core of making Iot more intelligent and scalable. SnappyUbuntuCore is the latest platform for smart devices. It promises to run the same software stored locally or on the cloud. Obviously, the biggest benefit of the latter is that users can avoid frequent regular upgrades. For Ubuntu, the biggest advantage of the platform
According to foreign media reports, Microsoft is planning to buy an Internet of things company from Italy, the Solair company is not only a traditional internet of things company, it provides services including those in the manufacturing, retail, food, beverage and transportation and other traditional industries. Azure IoT lead Sam George says Solair is able to add new intelligence to the internet of things through some data that has not yet been full
Iot is a broad concept and is not a new concept. Looking at some weak media reports that the application of a certain QR code is very boring, I don't know whether the media is shameless, or the readers are all idiots. Do not drag the Internet of Things like the QR code or RF.
Iot is neither a new concept nor a new technology. More objectively speaking, Iot only

the constrained Application Protocol (coap) is a software protocol designed to enable very simple electronic devices for interactive communication over the Internet. It is especially designed for small low-power sensors, switches, valve doors and components that require remote control or supervision over standard Internet networks. Coap is an application layer protocol used to connect dev
with Kinomacreate. The kinomacreate supports JavaScript version fifth, and the XS virtual machine is optimized for IoT devices.Kinomajs is a new JavaScript framework that is designed to be used to develop applications for connected devices and mobile devices. With KINOMAJS, developers can quickly connect to the basic components of any IoT device, including user experience, network communications, digital m

The goal of this page was to help testers assess IoT devices and applications in the Internet of things spaces. The guidance below is at a basic level, giving testers of devices and applications a basic set of guidelines to consider F Rom their perspective. This isn't a comprehensive list of considerations, and should is treated as such, but ensuring s are covered would greatly improve the security of any

IBM was one of the first companies to announce their development plans for the blockchain, which has established multiple partnerships at many different levels and demonstrated their fondness for blockchain technology. It has published a report stating that blockchain can be the best solution for the internet of things. In January 2015, IBM announced a project--adept project, a research project using peer-to-peer blockchain technology. IBM has also developed a proof-of-concept system with
Today to the bookstore to see a book called "C # Internet of Things Programming fundamentals " books, interested in the internet of things I grabbed to see, the book is the project is the host computer development projects, simpler, if the Internet of things development is just this, it seems that I do IoT development is more than enough. I looked at this book for more than 10 minutes, and the technical mishap made me face it. This book says using WPF
In the book "evolution of the Internet", we propose that "the future functions and structure of the Internet will be highly similar to that of the human brain, and the virtual perception of the Internet, virtual movement, virtual hub, and virtual memory neural system will be available"And draw a structure of the Internet virtual brain.
Based on this point of view, we try to analyze the relationships between the four most popular Internet concepts ----------- big data, cloud computing,
Comparison of four wireless technologies: Who is more suitable for the IOT field?
It is predicted that about 2020 devices will be connected via wireless communication by 50 billion. According to data from the GSM alliance, mobile handheld computers and personal computers only account for 1/4 of the total, while the rest are self-interconnected devices that use non-user interaction to communicate with other machines. At present, our Internet is rapidly
opportunities and development space, while some security issues surfaced, more and more physical devices connected to the Internet of things, coupled with the user's lack of security awareness, hackers can easily hijack physical devices into zombies, and manipulate these devices to launch a DDoS attack. So what do equipment manufacturers and IDC operators need to do to deal with such DDoS attacks?First device manufacturers need to add secure program settings in the terminal, now hackers can eas
