LoRaWAN-Based Reference Design For Smart Home And Buildings


Comprises of 2 integrated circuits that reduce power consumption, support high data rates and increase the performance of modulators and demodulators

Semtech Corporation, a leading supplier of high-performance analog and mixed-signal semiconductors and advanced algorithms, has launched the LoRa® Corecell reference design for indoor gateway applications. The reference design is based on the LoRaWAN protocol, designed especially for home, building and factory automations.

The LoRa Corecell reference design provides “minimum optimized solution” for building a gateway application (represented in the name, “core” and “cell”). This reference design comprises of 2 integrated circuits (ICs) – LoRa-based gateway baseband transceiver (SX1302) and low power multi-band Sub-GHz RF Front End (SX1250). The ICs reduce power consumption up to one-tenth the power of already existing products, thus enabling limited power USB-based gateways and mobile battery-operated gateways.


The new ICs allow reduced bill of materials (BOM), small package form factor while increasing the performance of a larger number of modulators and demodulators. In addition, factor five and factor six were added to support higher data rates, reducing time on air and power consumption.

LoRa-based Gateway Baseband Transceiver (SX1302)

LoRaWAN® Class A/B/C has a 125 kHz LoRa reception with 8 x 8 channels LoRa packet detectors, 8 x SF5-SF12 LoRa demodulators, 8 x SF5-SF10 LoRa demodulators and 125 /250 / 500 kHz LoRa demodulator.

Multi-band Sub-GHz Radio Frequency Front End (SX1250)

It has +22dBm Output power with lower UHF bands 169 and 433 or 490 MHz. It comes in a 24QFN (4mmx4mm).

“The LoRa Corecell reference design’s key features, including low power, smaller package and higher integration with improved performance, aim to eliminate design complexity and accelerate time-to-market in the smart home and building industries,” said Pedro Pachuca, Director of IoT for Semtech’s Wireless and Sensing Products Group. “As we announced earlier this year, Semtech is committed to developing a LoRa product roadmap that simplifies Internet of Things (IoT) applications that enable a faster time-to-market for IoT solution providers and systems integrators. This new reference design is key to our LoRa offerings as more real estate and commercial managers, as well as consumers, look for solutions that solve their daily challenges, such as meeting room occupancy and temperature/humidity monitoring.”
