How can you overcome rain fade to ensure reliable satellite communication?

Heavy rain disrupts satellite links, leading to data loss and downtime. Advanced RF solutions, however, are engineered to maintain a highly stable connection even in severe weather, minimizing disruptions and maximizing uptime. To overcome rain fade, you must combine a sufficient power margin with dynamic techniques. The best approach uses Uplink Power Control (UPC)1 to boost signal strength and Adaptive Coding and Modulation (ACM)2 to make the signal more robust, ensuring the link remains active during heavy rainfall. I learned about rain fade the hard way. Early in my career, I believed that designing a satellite system with a 3-5 dB link margin was enough to handle any weather. I […]
