An RSTAR L900 System uses L900 RSTAR

at the sensor level, deployed in a star topology

from a continuously active L900 RSTAR

, which consists in a L900

interfaced to a

datalogger. The system is based on the 900 MHZ, 868 MHz and 2.4 GHz spread spectrum band (country

dependent) with extensive open-country range through use of simple dipole or directional antennae.
