Satellite Communications & Mesh Networking

A terminal uses an antenna and radio equipment to exchange data with a satellite. A modem connects the terminal to a compatible satellite network and service. A local mesh radio network can connect teams at the scene, with satellite providing a separate link back to headquarters.

A command vehicle can send video, maps and incident reports back to headquarters when terrestrial coverage is weak or disrupted. Rescue and fire vehicles may also need dispatch connectivity at remote or temporary sites. Use a parked antenna when the link is needed after arrival, or a tracking terminal and compatible service when it must work in motion.

Common satellite links use about 11–12 GHz down and 14 GHz up for Ku, and about 20 GHz down and 30 GHz up for Ka. Ka can support high-capacity spot-beam services. Both are affected by rain, with Ka generally more sensitive under comparable conditions. Actual capacity and availability depend on the service and link design.

Start with the vehicle’s actual route and work sites. For cross-border routes, verify beam coverage and service continuity in each country. For a defined local area with high video demand, compare Ka where the operator offers suitable capacity. In heavy-rain regions, compare both bands using the operator’s availability figures and rain margin. Check terminal compatibility, unobstructed sky view and local permissions before specifying the antenna.
