Technical meaning :--
Technically, is a chipto be plugged into computers, printers,mobile phones, etc. Designed by taking
the information normally carried by thecable, and transmitting it at a specialfrequency to a receiver Blue tooth chip
which will then give informationreceived to these mobile devices.

How Does It W ork?
Bluetooth is a standardfor tiny, radio frequencychips that can be pluggedinto your devices
These chips were designed totake all of the information thatyour wires normally send, and
transmit it at a specialfrequency to something
called a receiver Bluetooth chip.

Avoiding Interference : HoppingBluetooth uses a technique called spread-spectrum
frequency hopping.
In this technique, a device will use 79 individual,randomly chosen frequencies within a designated range
Transmitters change frequency 1600 times a second
