LoRa Edge Platform Streamlines IoT Design and Cuts BOM Costs

Designing for the Internet of Things (IoT) is increasingly complex. With over 500 billion devices projected to connect by 2034, companies need robust strategies that provide precise location and efficient energy use without inflating costs.

IoT touches every facet of daily life—from wearable health monitors to expansive asset‑management networks—requiring reliable, long‑range, low‑power communication that can span several kilometres.

These devices are often expected to operate for up to eight years. Continuous data streams are rarely needed; instead, infrequent, low‑bitrate transmissions are sufficient. Low‑Power Wide Area Networks (LPWANs) satisfy these requirements with minimal power draw, excellent coverage, and scalability.

Semtech’s new LoRa Edge platform brings together an ultra‑low‑power LoRa transceiver, GNSS, and Wi‑Fi scanning in a single chipset. By eliminating separate GNSS and Wi‑Fi modules, LoRa Edge slashes Bill‑of‑Materials (BOM) costs while delivering the right mix of location accuracy and energy efficiency.

LoRa is already proven in mission‑critical applications such as long‑range sensor readouts and street‑lighting control. Its sub‑GHz modulation supports data rates from 0.3 kbps to 50 kbps, with transmission distances up to 15–20 km; even in dense urban settings, links over 2 km are reliable.

"LoRa is long‑range and extremely low power—enabling tiny trackers with long battery life," said Olivier Beaujard, Senior Director of the LoRa Ecosystem at Semtech. "In utilities, water, gas, and asset management, this technology makes a tangible difference," he added.

LoRa’s architecture consists of a proprietary Physical (PHY) layer based on Chirp Spread Spectrum (CSS) and a Media Access Control (MAC) layer known as LoRaWAN. End‑points communicate with a star‑topology network, connecting via a single hop to gateways that can serve multiple gateways for redundancy.

The first LoRa Edge chipset with geolocation, the LR1110, captures portions of satellite broadcast signals. These signals are aggregated into a Navigation (NAV) message and forwarded to the cloud. The GNSS scanner supports GPS L1 + GPS GEO, SBAS (EGNOS + WAAS), and BeiDou B1 + BeiDou GEO/IGSO.

LoRa Edge is an all‑in‑one chipset suitable for indoor and outdoor deployments. It empowers customers to manage total cost of ownership by paying only when an asset needs to be identified. Secure key provisioning at production and a streamlined join process simplify development while meeting stringent security requirements. Together, LoRa Edge and Semtech’s LoRa Cloud geolocation services provide a unique architecture that dramatically reduces power consumption.
