The Marketing Minute: Marketing Is a Team Sport
Semtech Corporation, a leading provider of high-performance semiconductor, Internet of Things (IoT) systems and cloud connectivity service solutions, announced that LoRa® technology will continue to serve as the core radio modulation for Amazon Sidewalk across all markets in this year’s Sidewalk international expansion.
Amazon Sidewalk, a wireless community network operated at no charge to customers that helps devices work better and stay connected beyond home Wi-Fi range, currently covers approximately 95% of the U.S. population1. The expanded collaboration comes as Ring plans to launch its Amazon Sidewalk network globally in 2026. The rollout begins in Canada and Mexico later this month and expands to other regions later this year.
Since 2023, Amazon has chosen LoRa as the long-range connectivity solution for Amazon Sidewalk, enabling IoT sensors to operate beyond individual residences and to connect both stationary and mobile devices throughout neighborhoods. This technology transforms Amazon Sidewalk from a Local Area Network into a Wide Area Network, enhances network coverage and plays a key role in enabling the multi-continent expansion.
Amazon Sidewalk represents one of the largest consumer-facing LoRa deployments globally, joining the extensive industrial and enterprise LoRaWAN® networks that have established LoRa as the market leader in low-power wide-area connectivity. The LoRaWAN IoT connectivity market is experiencing explosive growth, with industry analysts projecting the market will grow from $10.7 billion in 2025 to $44.8 billion by 2030, representing a compound annual growth rate of 33.1%. The LoRa Alliance® recently announced LoRaWAN deployments have surpassed 125 million devices globally, achieving a 25% CAGR.
“Amazon Sidewalk has consistently been building a secure, community network solving IoT’s hardest problem: invisible, reliable connectivity,” said Jay Desai, general manager at Amazon Sidewalk. “Sidewalk transforms connected devices into trusted products by keeping them online when Wi-Fi fails during key moments, eliminating setup friction, and enabling services previously impractical at scale.”
“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, senior vice president and general manager, analog mixed signal and wireless products group at Semtech. “As Sidewalk scales to serve tens of millions of devices globally, LoRa’s unique combination of long-range connectivity, ultra-low power consumption and proven network scalability makes it a great foundation for community IoT networks that deliver real value to consumers.”
LoRa Enables Sidewalk’s Technical Evolution
Chirp spread spectrum (CSS) modulation in LoRa technology provides the technical foundation enabling Amazon Sidewalk’s new capabilities:
Enhanced Network Density: LoRa multi-spreading factor capability optimizes longer range and shorter time-on-air, supporting higher device concentrations in urban environments while maintaining reliable connectivity.
Location-Based Services: Unique location accuracy service that combines the power of Wi-Fi, Bluetooth Low Energy (BLE) and GPS enables a new class of location aware devices that don’t need expensive cellular solutions for asset tracking applications.
Hub-Less Deployments: Utilized for both out-of-band-diagnostics as well as signaling radio for battery-powered cameras, LoRa lowers the need for hubs/repeaters, reducing infrastructure complexity for consumers while extending effective coverage areas.
Proven Heritage in Massive IoT Networks
Semtech’s LoRa technology has been deployed by more than 170 major mobile network operators globally, with over 500 million connected devices across smart cities, utilities, logistics, unmanned aircraft systems, and industrial applications. This proven deployment heritage provides the technical foundation and ecosystem maturity required for Amazon Sidewalk’s global expansion.
The technology’s long-range capability, extending connectivity up to several kilometers from Sidewalk bridge devices, combined with its ability to penetrate buildings and operate in dense urban environments makes it uniquely suited for neighborhood-scale networks. LoRa provides free, long-range connectivity that consumers can rely on for years of battery-powered operation.
Building on CES 2026 Momentum
Ring showcased its expanded product portfolio using LoRa at CES 2026, introducing comprehensive sensor families for security, safety and home automation. These products join the growing network of devices powered on Sidewalk, including water leak and freeze detection sensors, wearable devices and environmental monitoring solutions, all leveraging the connectivity advantages of LoRa.
The Sidewalk network’s architecture—combining LoRa for long-range communication with Bluetooth Low Energy for device setup—creates a robust, resilient IoT infrastructure that can scale to support millions of devices while maintaining the ultra-low power consumption critical for battery-operated sensors and cameras.
