LoRa is a new, private and spread-spectrum modulation technique which allows sending data at extremely low data-rates to extremely long ranges.
Libelium has added long-range wireless coverage to Waspmote sensor nodes, by integrating Semtech’s LoRa™ RF technology in a new module-on-a-chip embedded radio design for Smart Cities and Internet of Things (IoT) deployments.
Libelium’s LoRa module 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.
Waspmote sensor nodes are designed to deploy by the thousands, connecting any sensor using any communication protocol to any Cloud system. The LoRa communication protocol extends wireless connectivity so that Waspmote 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 Waspmote long-range module can receive data packets transmitted through difficult conditions and long links, thus reducing infrastructure costs for city uses.
