As you can see, the transmission does take place on the right and left side around the central 868.0 MHz axis. A bit like a mirroring image. This is called "Double Side Band" (DSB) communication in the radio area with the carrier wavelength set to 868.0 Mhz. | As you can see, the transmission does take place on the right and left side around the central 868.0 MHz axis.
