What are the non-military applications of frequency hopping? Why is it selected Bluetooth used in home devices and wireless computer mouse?

What will be an ideal response?


If any part of the spectrum being used by mobile devices in an area is subject to
interference, then all the communication between them is affected. However, if
they chose to change (hop) their frequency in a predetermined manner, then only
the transmissions in the noisy part of the spectrum are affected. This greatly
enhances the communication possibilities between the devices.
Bluetooth operates in 2.4 GHz ISM band which is shared by number of other
wireless standards. Even if there is interference on one frequency channel, it
might not be these when it hops to the next frequency selected on a random basis.
Hence, frequency hopping ensures minimum interference during transmission by
other wireless standards. It also guarantees a high security without requirement of
high computation power.
