What is FHS (Frequency hopping synchronization)?

Frequency hopping synchronization is an association between a master (M) and slaves (S) results from a frequency-hopping algorithm orchestrated by the master (M), and which is dispersed between slaves (S) by means of phase synchronization. This provides slaves (S) equivalent time for availability. Frequency hopping is a communication scheme utilized in Bluetooth-empowered devices between a transmitter and a receiver.
