Here's a story about the quiet, invisible networks that are starting to connect everything around you. Semtech Corp. (SMTC) announced that its LoRa technology will remain the core radio tech for Amazon.com Inc.'s (AMZN) Sidewalk network as it goes global. Think of it as the plumbing for Amazon's ambitious plan to build a free, wide-area wireless network that keeps your smart devices connected even when they wander out of your home Wi-Fi's reach.
From Backyard to Border
Amazon Sidewalk is already a big deal in the U.S., covering about 95% of the population. Now, it's getting passports. The global rollout kicks off later this month in Canada and Mexico, with more regions planned for later this year. For Semtech, this is a major validation. Amazon Sidewalk represents one of the largest consumer-facing deployments of LoRa technology in the world.
The backdrop here is an Internet of Things (IoT) market that's not just growing—it's exploding. According to industry group the LoRa Alliance, the LoRaWAN IoT market is projected to balloon from $10.7 billion in 2025 to $44.8 billion by 2030. That's a compound annual growth rate of 33.1%. Meanwhile, global LoRa deployments have already surpassed 125 million devices and are growing at a 25% clip. Amazon's global push with Sidewalk is a bet that this trend has a very long runway.
The Invisible Connector
Since 2023, Amazon has used LoRa as the long-range workhorse for Sidewalk. The tech's claim to fame is letting low-power IoT sensors—think pet trackers, leak detectors, or smart lights—communicate over surprisingly long distances, stitching together neighborhood-wide coverage from what was once just a local network.
"Amazon's embrace of LoRa as the core connectivity technology for Sidewalk validates our vision of enabling the Internet of Things through proven, scalable wireless connectivity," said Madhu Rayabhari, a senior vice president at Semtech. The company touts LoRa's long range, low power needs, and ability to scale as key reasons it works for massive IoT projects.
Jay Desai, general manager at Amazon Sidewalk, summed up the goal simply: delivering "invisible, reliable connectivity." It's the kind of tech you're not supposed to think about, until your dog runs off and you're very glad it's there.
