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...

    Why Bluetooth Channel Sounding Leads High-Accuracy Location Services
    With its well-known audio streaming and data transfer capacities, Bluetooth® technology with has become a ubiquitous part of our lives, powering everything from wireless headphones to smart home devices. But did you know that Bluetooth is now leaping towards high-accuracy location services, thanks to a groundbreaking technique called Bluetooth Channel Sounding? In this blog, we'll explore what Bluetooth Channel Sounding is, how it works, the benefits it brings to location services, which use cases benefit from high-accuracy distance measurement (HADM), and why it's such a game-changer in the world of connectivity. Figure 1 Why Bluetooth Channel Sounding Leads High-Accuracy Location Services What is Bluetooth Channel Sounding? Channel Sounding, previously known as high-accuracy distance measurement (HADM), is a new technique to calculate the distance between two Bluetooth devices. It uses phase-based ranging(PBR) on multiple channels to obtain an accurate distance measurement. Does it sound complex? At its core, the principle of Channel Sounding is simple. How Bluetooth Channel Sounding Works? Look at the picture of the Channel Sounding procedure and let’s explore the principle in an easy way. Figure 2 The Channel Sounding procedure Device A sends a radio signal to Device B, whereupon Device B measures the phase of this signal and transmits it back to Device A with that same phase. Following this, Device A assesses the phase variance between the transmitted and received radio signals to determine the distance traversed by these signals at the time of flight. This procedure is repeated multiple times over different channel frequencies, thereby the Bluetooth devices can estimate an unambiguous distance in a precise way using phase data. The upcoming feature brings good news to the increasing number of Bluetooth devices, especially the ones with location services. What are Benefits of Bluetooth Location Services with Channel Sounding? The benefits of Bluetooth location services with Channel Sounding are vast and impactful. Here are the key advantages: High-Accuracy of Up to 10CM Despite the proven utility of existing Bluetooth ranging technologies, their precision in distance measurements may fall short for more challenging use cases. The ubiquitous received signal strength indicator (RSSI) technique, available on all smartphones, estimates the distance between two devices based on the decline of the signal's amplitude. Regrettably, the accuracy of this method is generally limited, often ranging from three to five meters. Besides, RSSI remains vulnerable to interference from external factors, such as absorption and diffraction. After that, more advanced techniques in distance ranging accuracy are born - Angle of arrival (AoA) and Angle of departure (AoD). Instead of directly estimating distance, AoA and AoD utilize trigonometry to derive distances from the angles of incoming or outgoing radio signals. This methodology can achieve sub-meter accura...
