VHF communication channel characterisations over complex wooded propagation paths with applications to ground wireless sensor networks

Abstract

Results of measurement trials to estimate path loss and signal fading levels in very-high frequency band are presented for a node-to-node ad-hoc sensor network communication link with very low elevated antennas. Different typical landscapes were tested; from flat open areas to uneven woodland areas. Practical recommendations regarding utilisation of VHF band are formulated. © The Institution of Engineering and Technology 2013.
