Bluetooth frequency hopping basics

WebThe Bluetooth standard is based on frequency hopping spread spectrum technology. Although at any point in time, the Bluetooth signal occupies only 1MHz, the signal changes center frequency (or hops) deterministically at a rate of 1600Hz. Bluetooth hops over 79 center frequencies, so over time the Bluetooth signal actually occupies 79MHz. Webfrequency hopping method from BR and EDR to transmit efficiently. [1] Note that for Bluetooth LE there are only 3 channels in use for broadcasting as well as for connecting …
