Resumen
In this contribution, we present a narrowband radio channel model for a scenario wherein
the radio link operates under near-ground conditions, occurring on a ZigBee wireless sensor
networks applied to smart agriculture. A near-ground network deployment can be useful to avoid
tall antenna masts, or once crops grow. Among the examined scenarios, we analyzed path loss
caused when placing sensor ...

In this contribution, we present a narrowband radio channel model for a scenario wherein
the radio link operates under near-ground conditions, occurring on a ZigBee wireless sensor
networks applied to smart agriculture. A near-ground network deployment can be useful to avoid
tall antenna masts, or once crops grow. Among the examined scenarios, we analyzed path loss
caused when placing sensor nodes in soil, short and tall grass fields. We measured the received
power when locating both transmitter and receiver antennas at two different heights. The path loss
was then estimated as dependent of the radio link range. In another scenario, RSSI were obtained
to analyze the communication quality between sensor nodes using same antennas heights as the
previous scenarios, only for the case of a short grass field. [--]
