Semtech LoRa® Technology Helps Power Amazon Sidewalk’s Global Expansion

Key Terms

loraWAN technical

LoRaWAN is a wireless networking protocol designed for connecting many small, battery-powered devices over long distances while using very little energy. It lets sensors and meters send short bursts of data — like temperature readings or location pings — to gateways that forward them to cloud services. Investors care because the technology lowers deployment and operating costs, enables large-scale Internet of Things applications, and creates market opportunities for chipmakers, device makers, network operators and service providers; think of it as a frugal postal system that carries brief messages from far-flung devices so they don't need frequent refueling.

iot technical

The Internet of Things (IoT) describes a network of everyday devices—such as appliances, vehicles, and equipment—that are connected to the internet and can share data automatically. For investors, IoT represents a growing trend that can drive efficiency and innovation across many industries, potentially creating new opportunities for growth and value. Its expansion influences how companies operate and compete in a digitally connected world.

chirp spread spectrum (css) technical

Chirp Spread Spectrum (CSS) is a way of sending radio signals that sweeps the signal’s pitch up or down over time—like a siren sliding between notes—so the message can be picked up even in noisy conditions or over long distances using very little battery. For investors, CSS matters because it underpins many low-power, wide-area wireless networks used in smart sensors and Internet-of-Things devices, influencing product capabilities, service costs, and competitive positions for companies in connectivity, industrial sensors, and telecom infrastructure.

bluetooth low energy (ble) technical

A short-range wireless technology that lets small devices like phones, fitness trackers, sensors and smart-home gadgets exchange tiny amounts of data while using very little battery power. Investors care because BLE determines how long products run, how easily they connect, and how cheaply manufacturers can add smart features — similar to how fuel efficiency affects a car’s appeal and running costs, which in turn influences sales and market growth.

gps technical

A global network of satellites and ground stations that provides precise location and time information to devices on Earth; think of it as a map and clock in the sky that tells a device exactly where and when it is. Investors care because GPS underpins navigation for shipping and delivery, fleet and asset tracking, location-based services, autonomous vehicles, and precise timing for financial networks—so changes in GPS technology, reliability, or competing systems can affect revenue, costs, and risk across many industries.

wide area network technical

A wide area network (WAN) is a communications system that links computers and office locations across cities, countries or continents so they can share data and applications as if they were nearby. For investors, a reliable WAN matters because it affects a company’s ability to operate smoothly, serve customers, scale to new markets and control costs and security risks—think of it as the highway system that determines how fast and safely goods (data) move between branches.

LoRa modulation becomes core connectivity standard for world’s largest license-free IoT network, expanding internationally in 2026

CAMARILLO, Calif.--(BUSINESS WIRE)-- Semtech Corporation (Nasdaq: SMTC), a leading provider of high-performance semiconductor, Internet of Things (IoT) systems and cloud connectivity service solutions, today 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.

Semtech LoRa Technology Helps Power Amazon Sidewalk's Global 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.
