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 will be 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

Raouti Chehih, Chief Adoption Officer at Sigfox

The first services from the strategic alliance are expected to hit the market in 2020.

Bluetooth 5.0 update for ESP32

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.

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.

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. To this end, Espressif’s chips and ESP-BLE-MESH, in particular, are designed to help customers develop easily secure and cost-effective products for smart homes, smart buildings, healthcare, new automobiles and other smart industries.

IoT Security with latest SLM 9670 Industrial Grade TPM 2.0

Like other embedded systems, Industrial IoT design faces a constant stream of threats. As hackers adopt new attacks, developers rush to close security holes. Deployed devices need to update IoT firmware, increasing potential security vulnerabilities. For example, using a simple firmware verification check can leave the software published. In this situation, the developer may expect to be able to query external resources for verification and catch attempts to replace the firmware with hacked code. However, even relatively novice hackers can replace the firmware with code that ignores such verification checks. To secure these vurnerabilities comes Industrial Grade TPM 2.0.

Securing devices with Infineon industrial grade TPM

Infineon Technologies AG has unveiled a new security chip that defines the first TPM (Trusted Platform Module), designed specifically for industrial applications such as industrial computers, servers, industrial controllers and edge gates. The module protects confidential data in connected devices and reduces the risk of leakage of this information due to attacks, e.g. hackers.

The OPTIGA TPM SLM 9670 module protects the integrity of industrial systems and the identity of users using them. The system controls access to sensitive data at key locations in industrial environments, such as an automated factory. It also protects the cloud interface if the network uses one. The security system fully meets the TPM 2.0 standard developed by the Trusted Computing Group and is certified by an independent test laboratory in accordance with the criteria contained in this standard. The new module is meticulously controlled and certified by Infineon. Thanks to its use, it is possible to shorten the time of designing and introducing the device to the market, thanks to the ready security solution in the system.

The TPM system has a lifetime declared as 20 years. It allows programmers to perform firmware updates, which in turn enables them to meet the long-term security requirements in rapidly changing industrial environments. In this way, it can also reduce maintenance costs of industrial equipment thanks to secured remote software updates. The TPM chip will be available in serial production in the second half of 2019.

TPM 2.0 Key Features

  • Random Number Generator (RNG) according to NIST SP800-90A
  • TPM FW update functionality installed
  • 6962 Bytes of free NV memory
  • Full personalization with Endorsement Key (EK) and EK certificate
  • Up to 3 keys in the volatile memory
  • Up to 7 keys in the NV memory
  • Up to 8 NV counters
  • Support of various cryptographic algorithms:
    • RSA-1024 and RSA-2048
    • SHA-1 and SHA-256
    • ECC NIST P256
    • ECC BN256

Security chip implementation in Industrial IoT devices

With knowledge of latest Industrial IoT security measures, the choice of proper end-point conroller or gateway is much easier than you think. Some manufacturers can implement TPM 2.0 security chip in production process, to allow users to generate certification keys after purchase, maximizing security of their installations. TECHBASE offers wide range of solutions, optionally aided with TPM system.

For example, ESP-32 based solution, Moduino X series and eModGATE series products offer the support for such security measures. Read more in Industrial IoT Ecosystem brochure, to understand the importance of reliable and secure hardware for Industrial IoT.
