The USB Type-C connector has become the universal interface of modern electronics. From laptops and smartphones to Artificial Intelligence (AI) computing platforms and industrial edge devices, USB Type-C supports both high-speed data transfer and high-wattage power delivery through a single cable. With the adoption of USB Power Delivery (USB PD) 3.1 and its Extended Power Range (EPR), (Table 1) VBUS line voltages have scaled from the familiar 20V/100W standard power range to 28V, 36V and 48V — enabling power delivery of up to 240W over a USB-C cable.

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.

长期以来，亚洲一直被公认为物联网 (IoT) 采用最具活力的地区之一，而 2026 年亚洲科技新加坡展 (ATxSG) 让这一现实不容忽视。Semtech 和 LoRa Alliance® 将其完整的生态系统带到了此次活动中，反响完全符合团队的预期。
LoRa 联盟展馆汇聚了众多网关制造商和终端节点开发商，吸引了络绎不绝的人流，引发了有意义的技术交流，并且至少出现了一个具有里程碑意义的商业时刻，这表明 LoRaWAN® 在亚太地区取得了多么巨大的发展。
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.

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 “这项技术有效吗？” 但是 “我能放心地将我的数据、器件以及合规义务托付给它吗？”
The answer for LoRaWAN® is a confident yes and here's why.
