The biggest deployment challenge for the Aviat link was the region’s topology and configuration of the system for optimal reliability as it transmitted over hilly terrain and farmland. The link also crosses over the Shannon Estuary, which constitutes 16 percent
of the path. Reflection is the biggest challenge when transmitting radio frequency over water. It can result in multi-path signals, which can slow the network down considerably. Tidal patterns also were considerations, as changing tides alter thermal conditions and vary the degree of reflection. It is challenging to install a high-capacity link with a high modulation scheme over water.
