LoRaWAN eval kits enable low power, long range networking

This product is featured in EDN's Hot 100 products of 2016. See all 100 here.
Microchip Technology's kit includes a LoRaWAN gateway, two sensors, and a local server application: all the required components to create a low-power wide-area network in Europe (DV164140-1 for the 868 MHz band) or North America (DV164140-2 for the 915 MHz band).

Each kit includes two Motes (LoRaWAN sensors) based on Microchip’s RN2483 or RN2903 LoRa modules, a LoRaWAN gateway and a local LoRaWAN server application. Driven by the LoRa Alliance, LoRa technology is able to achieve a range of up to 16 km and 10-year battery life. The technology targets low data rates and low-duty-cycle applications for tracking and monitoring such things as energy, location, utility infrastructure, smart city, environment, agriculture and public safety. Although predominantly used for the uplink of sensor data, bidirectional communications allow real-time acknowledgement of mission-critical data and downlink control of remote actuator nodes.

Each kit can serve as a building block for development of a long-range LoRa network where designers can expect up to 16 km of range and 10 years of battery life using two AAA batteries. LoRa technology employs spread spectrum modulation which delivers data robustness in a noisy environment and works through physical obstructions. Because the two Motes are European R&TTE Directive Assessed (DV164140-1) or FCC Certified (DV164140-2), time to market can be significantly reduced through simplification of standards and government regulatory certification.
The DV164140-1 and DV164140-2 are priced at $499.00 each.
