Receiving sat signals without dishes? From some trials we had on a telco I used to work, You would need to use a network of low-orbit satellites, carefully choosing the better frequencies and it will provide you low bandwidth. This will likely cost a lot of money, if you find someone providing a service like that. One trial for such network were the Iridum project. AFAIK, the original company bankrupted due to the very high costs of launching and managing about a hundred satellite network. I'm not tracking such things nowadays, but I won't doubt that you would find someone providing this kind of services. I think the telephones that are onboard of some flight companies use a satellite service like that. > Probably by introducing some _very_ redundant code inside the stream > that we upload through the modem and that the satellite will stream from > the sky, we can get some S/N db.
