Waspmote is an open source wireless sensor platform specially focused on the implementation of low consumption modes which allows the sensor nodes ("motes") to be completely autonomous, that is battery powered. Lifetime of Waspmote sensor nodes may go from 1 to 5 years depending on the duty cycle and the radio used.
LoRaWAN is a new, private and spread-spectrum modulation technique which allows sending data at extremely low data-rates to extremely long ranges. The low data-rate (down to few bytes per second) and LoRaWAN modulation lead to very low receiver sensitivity (down to -136 dBm), which combined to an output power of +14 dBm means extremely large link budgets: up to 150 dB, what means more than 22km (13.6 miles) in LOS links and up to 2km (1.2miles) in NLOS links in urban environment (going through buildings).
Waspmote is based on a modular architecture. The idea is to integrate only the modules needed in each device optimizing costs. For this reason all the modules (radios, sensor boards, etc) plug in Waspmote through sockets.
You will need batteries to use Waspmote as an autonomous device.
