Wi-SUN Products Launch Anouncement!  ——RFstar Has Joined Hands with TI to Develop Wide-Area Mesh!
Jun 24, 2022 Wi-SUN Products Launch Anouncement! ——RFstar Has Joined Hands with TI to Develop Wide-Area Mesh!
Recently, RF-star, a veteran wireless IoT company in China, announced that it has joined hands with Texas Instruments to launch several Wi-SUN products, focusing on the development of wide-area mesh, hoping to provide customers with integrated solution development environment of end-edge-cloud in the field of industrial IoT and public facilities. The products disclosed by the company include a variety of Wi-SUN communication modules based on the TI CC1352 and CC1312 series, which support Sub1G multi-band and 2.4GHz communication, and support self-organizing networks by mesh and multi-hop. The distance of a single hop can reach several kilometers. Development history of Wi-SUN Even for most people in the IoT circle, Wi-SUN is a new technology. Actually it has been created for more than a dozen years. However it floated only in recent years after more major chip vendors and device manufacturers joined the technology alliance and started to promote the technology. As early as 2008, there was no unified wireless communication standard for the Wide Area network in the industry, while there were various wireless communication protocols in the industry at that time. What these protocols have in common is that they adopted the IEEE 802.15.4 standard. But they still cannot achieve interconnection in the application layer. In order to solve this complex problem, Wi-SUN FAN (Wireless Utility Field Area Network), a large-scale wireless mesh network based on IP technology came into being. The standard is committed to becoming the global wireless mesh network standard with interoperability. With the implementation of the standard, Wi-SUN alliance was established in 2012. Currently, the alliance has more than 250 members worldwide, including Cisco, ARM, Texas Instruments and Itron, etc. Over the past two years, the Wi-SUN standard has matured, and hundreds of millions of Wi-SUN enabled devices have been deployed worldwide. It is widely used in public utilities and smart city facilities due to its feature of enabling smart meters, smart street lights and other devices to be connected to a public network. Wi-SUN technology is an open specification based on IEEE 802.15.4g, IEEE 802 and IETF IPv6 standard protocols. Wi-SUN FAN is a mesh network protocol that support self organizing and self-healing functions. Each device in the network can communicate with its neighbors, and signals can be transmit to each node in the mesh, making very long range hops in between. Wi-SUN features long distance transmission, security, high scalability, interoperability, easy deployment, mesh network, as well as low power consumption (the battery life of Wi-SUN modules has a chance to It can be used for ten years). It is widely used in smart meters and family intelligent energy management (HEMS) controllers for communication, and is also conducive to building a wide-area large-scale internet of things. The Wi-SUN standard mainly consists of two sub-specifications, namely FAN and HAN. ...

Beacon Technology Makes Indoor Positioning Easier
Oct 29, 2021 Beacon Technology Makes Indoor Positioning Easier
The IoT technology is constantly updated and iterated, and the indoor positioning technology has also undergone earth-shaking changes. From room-level positioning, decimeter-level positioning to high-precision centimeter positioning, the evolution of technology is always unexpected! Various positioning technologies of indoor positioning solutions appear in turn. Which technology is most suitable for indoor positioning? Let’s take a comprehensive perspective to understand the Bluetooth indoor positioning solution. Overview of Beacon Indoor Positioning Technology There are two Beacon indoor positioning technologies: 1. Passive location: Use the Bluetooth gateway to capture the broadcast data transmitted by the beacon on the person/object. The gateway is deployed and installed in the environment. And the gateway will return the collected beacon data to the server through the network. The server obtains the real-time position coordinates of the beacon through a positioning algorithm based on the coordinates known by the gateway. 2. Active position: Use the APP on a mobile device to get the Beacon broadcast data. The APP will have a positioning algorithm. Based on Beacon broadcast data, we can know the person's location who holds the mobile device. The location and navigation in the room are realized through APP or Applet, which is suitable for shopping malls, parking lots, and hospitals. Features of Beacon indoor positioning technology Compared with Wi-Fi positioning technology, Beacon technology suffers less environmental interference. Beacon product is based on the battery power supply. With the advantages of Bluetooth low energy consumption, long service life, small size, and the high penetration rate of Beacon devices, Bluetooth positioning is the most commonly used technology in indoor positioning technology. In daily life, smartphones and smart speakers support Bluetooth. The popularity and mass use of Bluetooth makes Bluetooth chips at a low price. And the BLE price is lower than traditional UWB/RFID solutions. How does Bluetooth realize indoor positioning? The Bluetooth working frequency is 2400 MHz ~ 2483.5 MHz. When Bluetooth initiates a broadcast, in addition to its own MAC address, the strength of the Bluetooth signal will also be broadcasted, namely RSSI information. The RSSI reflects the signal strength of the broadcast data packet. According to the RSSI, when the Bluetooth receiver is closer to the transmitter, the signal strength is stronger, on the contrary, will be weaker. The relationship between the signal strength and the distance from the transmitter can be found through the transformation of signal strength. By deploying a Bluetooth transmitter in the room, namely a beacon, the Bluetooth receiver can determine its indoor location after receiving the RSSI signal broadcasted by the transmitter. This positioning method is called active positioning, and the positioning accuracy is 3 meters to 4 meters. Through a reasonable algorith...

IoT Security Made Simple with SimpleLink™ Wi-Fi® RF-star CC3100 and CC3200 Module RF-WM-3200B1
Mar 06, 2019 IoT Security Made Simple with SimpleLink™ Wi-Fi® RF-star CC3100 and CC3200 Module RF-WM-3200B1
The Internet of Things (IoT) connects billions of devices and brings a huge opportunity for businesses to grow. However, billions of new connected devices also brings billions of new opportunities for hackers to steal intellectual property (IP), compromise users’ property and invade their privacy. While consumer awareness for Internet security grows as more security breaches at large companies are revealed to the public, secure Internet communication technology has advanced to a level that provides online banking, e-commerce and government services. State-of-the-art Internet security relies on advanced cryptographic algorithms, powerful computers and collaboration between major Internet companies and users. The common security capabilities available to Internet applications today include the following: Private communication – Information exchanged between parties is encrypted, such that an eavesdropper cannot understand it. End-point authentication – Communicating parties confirm each other’s identity prior to any information exchange to prevent attackers from using a false identity to access information and gain unauthorized control of a remote device. Information authentication – Critical information including transaction data and software updates are digitally signed to authenticate its origin and prevent malware installation. These security capabilities largely rely on a few fundamental building blocks, including: Stable cryptographic ciphers such as the Advanced Encryption Standard (AES), Secure Hash Algorithm (SHA2) and the public key ciphers RSA and ECC. When used properly with an adequate key size, these ciphers have no known practical attack. The Transport Layer Security (TLS) protocol, superseding its predecessor Secure Sockets Layer (SSL) protocol, provides the framework for establishing a secure communication channel between two parties. It handles both information encryption and end-point authentication, and relies on the cryptographic ciphers mentioned above. Public key infrastructure (PKI) provides the building blocks for authentication and trust through a digital certificate standard and certificate authorities (CA) such as Symantec and others. The benefit of using these well-known ciphers and protocols in IoT applications is two-fold. First, it relies on proven technology that is widely deployed and tested by the industry at a mega-scale. Second, it allows harnessing the power of already deployed Internet services (e.g. email, social media) as well as the public key infrastructure provided by CAs. Although Internet security technology is widely available, recent research from Symantec Security suggests that many deployed IoT devices have not implemented adequate security measures. There are likely multiple reasons for these security gaps, but vendor awareness, software complexity and implementation costs are probably at the top of the list. Many IoT devices are based on low-end microcontrollers (MCUs) that have limited processing...
Strengthening Wi-Fi security at the hardware level RFSTAR RF-WM-3220B1 W-iFi module
Mar 06, 2019 Strengthening Wi-Fi security at the hardware level RFSTAR RF-WM-3220B1 W-iFi module
If you’re an Internet of Things (IoT) designer, you’re probably often challenged to do more with less when it comes to security, constantly looking for new ways to protect your products against an ever-growing list of threats with lean system resources and perhaps limited experience. Knowing that these struggles are very real, in this post I’ll outline a few top IoT security risks and common misconceptions on how to address them. I will also provide an overview of how new CC3220SF Wi-Fi module RF-WM-3200B1 give you more tools to help address security challenges through a novel architecture and rich set of integrated security features. Are there IoT applications that don’t need to implement security measures? Any device that connects to the internet may be vulnerable to local or remote attacks. Attackers can target almost any connected device to try and steal manufacturer intellectual property stored in the system, gain access to user data, or even maliciously manipulate the system to compromise users or attack third parties online. As demonstrated by the major distributed denial of service (DDoS) attack late last year, labeled by experts as the largest of its kind in history, even seemingly harmless products such as home digital video recorders (DVRs) can be maliciously infected and used as “botnets” to halt operations for third-party entities. The attack last year affected services such as Twitter and PayPal, but similar attacks could potentially target large smart infrastructure technologies such as electric grid systems. According to a 2016 study conducted by Kapersky Lab, a single DDoS attack can cost an organization more than $1.6 million to resolve. Recognizing these threats,RF-star's CC3220SF Wi-Fi module integrates a host of powerful, multilayered and hardware-based security features to provide you with powerful tools to help protect products from attacks such as local or remote packet sniffing, man-in-the-middle (MITM) server emulation, hostile takeovers via over-the-air updates, remote file manipulation, data and software theft, intellectual property (IP) cloning, and many more. Watch the below video to learn more about these tools: Should IoT security features primarily focus on Wi-Fi and internet-level encryption of packets sent over the air? Having strong Wi-Fi (Advanced Encryption Standard [AES]/Wired Equivalent Privacy [WEP]) and internet-level (Transport Layer Security [TLS]/Secure Sockets Layer [SSL]) encryption is critical to help prevent local and remote network-packet sniffing, respectively. But these measures alone may not be enough to fend off hostile takeover attempts or provide full protection against theft of IP, code, data, keys and identity information stored and used in a connected system. Figure 1 illustrates these measures in action. Figure 1: Local network security features in action The CC3220 Wi-Fi module actually integrates more than 25 additional security features to help provide tools that address potential thr...

2016 CES Observation: Smart Home Promotes New Economic Growth Point RFstar to Participate in the Exhibition
Jul 08, 2017 2016 CES Observation: Smart Home Promotes New Economic Growth Point RFstar to Participate in the Exhibition
The annual CES (Consumer Electronics Show) opened in Las Vegas on January 6, 2016. As a world-renowned science and technology event, the concepts discussed in CES will become a hot topic in the next two to three years. However, in this CES, which seems to have no core theme, there are many things that are observed by interested people: the Internet of things, smart home, virtual reality, etc. More importantly, the combination of Internet of things and cloud computing. "Lazy economy" is being talked about by more and more people, or will become the new economic growth point of smart home in the next few years. An interesting phenomenon is that the concept of the lazy economy is very popular both at home and abroad. Although o2o has been used for many times since the beginning of the year, and now it has been slightly eased, the concept never seems to cool down. As Shahid Ahmed, a senior executive of PWC, said, "in the field of Internet of things, we have reached a turning point: the integration of consumer experience, digital technology and sensor technology." Fortunately, with the continuous development of related technologies, the smart home industry based on the home Internet of things can capture the "lazy economy" as a new growth field - the convenient life at your fingertips, which is the choice of the middle class who cares about saving time and is willing to try. What's more, "lazy people" are not idle, but to further liberate more time and energy to invest in more worthy areas. This coincides with the original intention of smart home interest: to make people's lives truly free and convenient through technology. What the "lazy man" requires is to work out the most reasonable scheme by intelligent calculation according to the actual situation in the simplest operation as possible, and to realize the requirements of accuracy and complexity as efficiently as possible. This requires not only technical support, but also the thinking close to the user's actual experience, otherwise it will become a chicken ribs. In fact, in the smart home industry, sharp manufacturers at home and abroad have caught the pass of this node, and timely launched a variety of products that are convenient for the user's life: sweeper robot, automatic fast food machine, intelligent lighting adjustment, intelligent door lock, etc. In terms of smart door lock, this CES is like the W2 walnut smart lock of CEI, which realizes the remote door opening and closing service of "cloud key", and provides a good experience for "lazy people" to break the space limit. It is worth noting that local excellent original manufacturers also have outstanding performance in the field of smart home, and they have also upgraded and fermented in the domestic market in recent years. There is no doubt that smart home based on "lazy economy" has great development potential. According to the latest report released by research and markets, it is predicted that the global smart home market will grow ...
