Abstract:
In the design of shore-to-shore and shore-to-vessel links, the impact of the signal reflections on the surface is often neglected. When choosing an antenna height for an inshore node, a typical decision is to use the largest possible height; but, this approach can lead to signal degradation. In this work, we aim to experimentally assess the impact of surface reflection on the received signal strength of a set of short-and-medium-range shore-to-shore links (<200 m) that use antennas installed at two heights, at a few meters above surface (<3 m). We observed considerable consistency between packet-based measurements of the received signal strength [indicator] (RSSI) and the two-ray model estimates. We conclude that these results provide strength to the claim that both the two-ray model and antenna height adjustment are key building blocks for an effective design of over-water links in coastal environments.
