Sigfox announces changes improving IoT applications

First major announcement is that Sigfox will launch a private network (PAN) that will allow IoT customers to choose private and global services according to their needs. The service was launched for the first time in France in the first quarter of 2020, but Sigfox will be implemented in over 65 countries.

The operator’s wide area network (WAN) will be completed next year in cooperation with Eutelsat. Sigfox provides coverage worldwide using the nano-satellite constellation launched by Eutelsat.

The Sigfox PAN offer will benefit from the existing Sigfox WAN ecosystem. Thanks to the potential to use all components on the market and the use of very low transmit power to support facilities without the need for batteries, the Sigfox PAN offer offers enormous potential,

Ludovic Le Moan, CEO and co-founder of Sigfox.

According to Sigfox, by the end of 2019, there will be more than 15 million registered facilities and over 1,500 customers using this solution in various industries around the world. Sigfox says that PAN customers can expect the same as WAN customers in terms of support and quality. PAN clients can choose to subscribe to additional „WAN Extension” services if needed if the device needs to communicate outside the local network.

Sigfox improving the accuracy of Atlas geolocation services

Internet of Things operators have now launched Atlas Native Complimentary. It is made available free of charge in exchange for the rights to process data regarding GPS data. These data are compared to the fingerprint of the Sigfox network using machine learning, which increases accuracy to 800 meters.

To further increase the accuracy of its geolocation services, Sigfox said it has completed the global implementation of Atlas WiFi in collaboration with HERE Technologies’ mapping experts.

Sigfox uses the global WiFi access point database here. Access points are checked by the Sigfox WiFi tracking module and more closely track the location of external and internal resources with less battery consumption than using GPS.

We are delighted to strengthen our partnership with Amadeus and share our combined expertise to create real digital transformation of the travel sector. Our strategic alliance named PinPoint will not only help to improve the travel experience, but this will also change completely the game for an industry looking for decades for THE technology able to save costs while improving efficiency and quality of services

eModGATE with ESP32

Industrial use of ESP32-based solutions

One of industrial IoT devices, supporting Sigfox wireless technology is eModGATE from TECHBASE. Economical, ESP32-based solution can serve as an end-point in any installation or works well as a gateway, gathering data from scattered sensor mesh across the installation. For more information check Industrial IoT Shop with all the configuration options for eModGATE.

ESP-MESH is a network protocol based on the Wi-Fi protocol. ESP-MESH enables the connection of a large number of devices (hereinafter nodes) covering a large physical area (both inside and outside) over a single WLAN (wireless local area network). ESP-MESH self-organizes and self-heals, allowing you to build and maintain networks autonomously.

Traditional Wi-Fi Network Architecture. Source: espressif.com

Traditional Infrastructure of Wi-Fi network is a point-to-multipoint network in which a single central node called an Access Point (AP) is directly connected to all other nodes called stations. The AP is responsible for arbitrating and forwarding transmissions between stations. Some access points relay transmissions to and from external IP networks through routers.

Traditional Infrastructure Wi-Fi networks have the downside of having a limited coverage area as all stations need to be in range to connect directly to the access point. In addition, the maximum number of stations allowed in the network is limited by the bandwidth of the access point, making traditional Wi-Fi networks prone to overload.

ESP-MESH vs traditional Wi-Fi infrastucture

ESP-MESH differs from traditional Wi-Fi infrastructure networks in that the nodes do not have to connect to a central node. Instead, the node can connect with its neighbors. Nodes are responsible for relaying transmissions to each other. This allows for achieving interconnections without the need for nodes to be within the range of the central node, which significantly extends the coverage area of the ESP-MESH network. Likewise, ESP-MESH is less prone to congestion as the number of allowed nodes in the network is no longer limited by a single central node.

Bluetooth LE 5.0/5.1 comming soon to ESP32-based controller

The Espressif’s flagship ESP32 chip recently passed the SIG Bluetooth LE 5.0 certification. This confirms that the version of the protocol supported by the ESP32 microcontroller has been upgraded from Bluetooth LE 4.2 to Bluetooth LE 5.0, which is more stable and compatible.

The implementation and development of the Bluetooth LE (BLE) application requires not only a system that supports this function, but also an attached Bluetooth LE protocol stack consisting of a driver and a host.

Bluetooth 5.0 update for ESP32

Thanks to Bluetooth LE 5.0 certification, ESP32 SoC not only updates the system as a whole, but also adds new features that improve the latest software after passing more stringent tests than previous certification.

Due to hardware limitations, ESP32 does not support such functions of Bluetooth LE 5.0 as 2M PHY, LE Long Range, and ADV Extensions.

It is also worth mentioning that the combination of Bluetooth and Mesh networking is expected to become a key technology for the Internet of Things. A  Bluetooth® Mesh network enables a „many-to-many” relationship among potentially thousands of wireless devices, where data are transmitted not in a direct radio range but in wide physical areas. Espressif’s contribution in this field is the ESP-BLE-MESH, which got fully certified by Bluetooth SIG in September 2019.

Several Bluetooth-operated products on the market, such as wearable devices, smart speakers, cleaning robots, smart lights/sockets, etc., provide evidence that Bluetooth 5.0 and the Bluetooth Mesh networking technology are mature enough to drive the development of interconnected IoT devices.
