The energy harvesting devices can also harvest their power from these ambient broadcast wirelesses TV signals. The usage of cross-polarized antenna MIMO scheme allows the video signals to be carried over multi-carrier frequencies via OFDM at much wider bandwidth in the UHF bands. The electronic devices operating at 3V or less than 3V can also be used to scavenge their power from such type of broadcasting by means of a dipole antenna. The condition is that the dipole should lie within a range of 6.5km from the source.
