Smart Cities

A software upgrade for LoRa ICs and gateways significantly increases network capacity, robustness to interference and enables a low power and reliable direct data links from sensors to satellites, says Semtech. The software enhancement can be leveraged by second generation LoRa ICs to enable the LoRaWAN standard new data rate, long range frequency hopping spread spectrum (LR-FHSS), which has been recently ratified by the LoRa Alliance.  

The suite of tools will be specifically enabled on Semtech’s LoRa transceivers: SX1261, SX1262, LoRa Edge platform and the V2.1 gateway reference design. For LoRaWAN networks where V2.1 gateways are deployed, operators can enable the new capability with a simple gateway firmware upgrade, advises Semtech. In addition to expanded capacity, LoRaWAN networks will be more robust in harsh radio conditions (deep indoor) and in some regions will offer the possibility to increase terrestrial coverage.

“As the smart cities trend continues to proliferate globally, the new capability is a step for Semtech’s LoRa platform toward massive IoT deployments in densely populated areas,” said Marc Pégulu, vice president of IoT product marketing for Semtech’s Wireless and Sensing Products Group. “In addition, the enablement of direct IoT to satellite services revolutionises the industry with affordable ubiquitous connectivity for remote areas, ultimately creating a smarter and more secure planet,” he adds.

Semtech’s LoRa device-to-,cloud platform is a long range, low power solution for IoT applications, that has been adopted around the globe, explains the company. It enables the rapid development and deployment of low power, cost efficient and long range IoT networks, gateways, sensors, module products and IoT services worldwide. 

Semtech’s LoRa technology provides the communication layer for the LoRaWAN standard, which is maintained by the LoRa Alliance. The open IoT alliance for low power wide area network (LPWAN) applications has been used to deploy IoT networks in over 100 countries. Semtech is a founding member of the LoRa Alliance. 

Semtech supplies analogue and mixed-signal semiconductors and advanced algorithms for infrastructure, high-end consumer and industrial equipment.

Capable of streaming four high performance USB3 board level cameras, the Quartet TX2 Embedded is the latest carrier board from Teledyne Flir.

The cameras can stream simultaneously and at full bandwidth. By eliminating peripheral hardware and host systems, it is suitable for space constrained applications. It is pre-integrated with the company’s Spinnaker software development kit (SDK) and offers scalable performance options.

The Quartet TX2 carrier board combines power and data transmission over a single cable per camera in a compact footprint of 138 x 92 x 18.2mm. It enables developers to create compact vision systems using Nvidia’s established TX2 computing module, integrating a powerful single board computer (SBC) into vision systems with limited space.

The Quartet TX2 carrier board can be used with up to four Blackfly S USB3 board level cameras. The Nvidia Jetson deep learning hardware accelerator also allows for decision-making system on a single, compact board. 

Teledyne Flir is a Teledyne Technologies company, specialising in in intelligent sensing solutions for defence and industrial applications. The company was founded in 1978.  

Teledyne Technologies provides sophisticated digital imaging products and software, instrumentation, aerospace and defence electronics and engineered systems. Teledyne’s operations are primarily located in the United States, the United Kingdom, Canada, and Western and Northern Europe.
