How 433Mhz and 868Mhz communication works

Communication on 433/868 works with radio frequency waves on those frequencies. These waves are transmitted and received by a radio transceiver with an antenna. On these bands, a couple of communication methods can be used, called radio modulations.

The most commonly used radio modulations on 433 and 868MHz are ASK (Amplitude-Shift Key) and variations of FSK (Frequency-Shift Key) like BFSK or GFSK. Basically, they define how data is transmitted: ASK uses differences in Amplitude (transmitting power) to create waves/data transmission. FSK uses slight differences in frequency instead. Nearly all 433/868 devices support just a single radio modulation. Often for controllers, this is ASK modulation for 433 and FSK modulation for 868 MHz. However, in order to enable our antenna to work with as many devices as possible, we have made sure that both radio modulations are supported on both technologies.
