1. The problem statement, all variables and given/known data The question wants us to determine what the power output of a 2.32 GHz geosynchronous satellite that has an antenna gain of 18 dB be for a mobile receiver that is operating with an effective antenna gain of 3 dB in order to achieve the FM threshold (6 dB). 2. Relevant equations Not sure 3. The attempt at a solution I'm not certain what to do with this problem at all. I know the altitude is about 36,000 km above the equator. I'm thinking of doing something with EIRP, but we don't have transmit power. I believe that the FM threshold of 6 dB is the C/N, but I'm not certain of that. It seems like we're missing info, but I was told that everything we need to solve the problem is given. What I really need is a boost in the right direction! If someone could give me a hint to help me get started, I'd be appreciative!
