Libelium has added long-range wireless coverage to the Waspmote Plug and Sense! by integrating Semtech’s LoRa™ RF technology in a design for Smart Cities and Internet of Things (IoT) deployments.
Libelium’s Plug & Sense! LoRa works in both 868 and 900 MHz ISM bands, which makes it suitable for virtually any country. As the 868 and 900 MHz frequency bands are lower than the popular 2.4 GHz band, the path loss attenuation is better in LoRa and experience fewer interferences. In addition, these low frequencies provide great penetration through materials (brick walls, trees, concrete), so experience less signal loss where obstacles are present. This LoRa communication protocol extends wireless connectivity so that the sensors can transmit data at distances of several miles, even through buildings, and over 20 miles in open spaces.
With LoRa’s high sensitivity of 138dBm, the Plug & Sense! can receive data packets transmitted through difficult conditions and long links, reducing infrastructure costs for city uses.
