France's municipalities are moving from pilot projects to full-scale Internet of Things (IoT) deployments and REX TCD Retours d'Expérience – Territoires Connectés et Durables (REX Connected and Sustainable Territories) has become the annual proving ground where that shift gets measured. Olivier Beaujard, Senior Director of the LoRa® Ecosystem at Semtech and Chair of the Board at the LoRa Alliance® attended the 3rd edition of REX TCD, held on June 16–17, 2026, at the Salons de l'Aveyron in Paris. Here’s what the event revealed about the state of connected territory development in France, and why LoRaWAN® is increasingly at the center of it.

Asia has long been recognized as one of the most dynamic regions for Internet of Things (IoT) adoption, and theAsia Tech x Singapore 2026 (ATxSG) expo made that reality impossible to ignore. Semtech and the LoRa Alliance® brought their full ecosystem to the event, and the reception was everything the team had hoped for.
Offering a rich representation of gateway manufacturers and end-node developers, the LoRa Alliance pavilion drew consistent foot traffic, meaningful technical conversations and at least one landmark business moment that signals just how far LoRaWAN® has come in the Asia-Pacific region.
Here is a look back at everything that made ATxSG a milestone event for the LoRaWAN community.

Buildings are among the world's largest consumers of energy and one of their most underleveraged sources of operational intelligence. According to the International Energy Agency, the building sector accounts for roughly 30% of global final energy consumption and nearly 26% of global energy-related emissions. Yet the vast majority of the world's existing building stock — the millions of offices, hospitals, factories, warehouses, schools, and retail spaces that people occupy every day — remains largely unconnected. Heating runs on fixed schedules rather than occupancy. Leaks go undetected for weeks. Equipment fails without warning. Space sits unused while teams compete for meeting rooms.

OFC 2026 in Los Angeles marked a defining moment for the optical and high-speed interconnect industry — and for Semtech. Held March 17–19 at the Los Angeles Convention Center, the show brought together the global optical communications ecosystem at a critical inflection point: Artificial Intelligence (AI) is fundamentally reshaping how data centers are built and the race to scale is pushing interconnect technology to move faster than anyone predicted.

When evaluating low-power wide-area network (LPWAN) technologies for internet of things (IoT) deployments, security is no longer a checkbox, it's a fundamental design requirement. As regulations tighten and cyber threats grow more sophisticated, the question isn't just "does this technology work?" but "can I trust it with my data, my devices, and my compliance obligations?"
The answer for LoRaWAN® is a confident yes and here's why.

The fourth generation of LoRa® technology is revolutionizing edge intelligence with breakthrough capabilities
The Internet of Things (IoT) landscape is undergoing a fundamental transformation. As artificial intelligence (AI) and machine learning (ML) move from the cloud to the edge, IoT devices face an unprecedented challenge: how to support intelligent applications that require higher data throughput while maintaining the long battery life and extended range that make wireless sensors practical in the first place.
Shahar Feldman, senior product marketing director for LoRa integrated circuits (ICs) at Semtech, recently presented how the company's new LoRa Plus™ technology addresses this critical challenge head-on, ushering in a new era of AI-enabled IoT deployments.
