WebMar 22, 2024 · Tropospheric scatter is a communications capability using the Troposphere (up to about 13 km altitude) to provide communications. The COMET system is small and lightweight with a maximum transmit power of 10-watts and utilizes a 1-meter dish, providing low latency (typically 9-20 mS) and large data links (5-60 Mbps) up to 60 km, but in … WebTroposcatter relied on relatively high-powered transmitters and large high-gain "billboard antennas" to "bounce" signals off of particles in the troposphere which is the lowest layer of the atmosphere. Depending on the power used, and the antenna sizes, a single tropospheric "hop" can span several hundred miles, which would require several ...
