We are looking for a solution capable of converting a signal 400-700 Mhz into 2.4 Ghz. Indeed, we would like to provide our value-added solutions via the TV frequencies to avoid interference.
Our subscribers use the smartaphones hence the need to transform the TV signal in wifi at home.
Thank you for kindly help us to find the solution.
What you described is simple frequency translation using a mixer and an oscillator. What you then describe is extracting the data from one signal, add some processing, and then modulating a second signal with the modified data. Totally different technology. Wonder what you really want?
