How does Bluetooth actually work ?

Bluetooth is the method for the short range communication between the electronic devices like mobile phones, computer and et all for the transfer and the data, file and other many types of information . Not only this the wireless mouse  and keyboard have been almost replaced by the system of the bluetooth. It is really cool kind of stuff . The range of the bluetooth of about 100 m.

The Bluetooth RF transceiver (or physical layer) operates in the unlicensed ISM band centered at 2.4 gigahertz (the same range of frequencies used by microwaves and Wi-Fi). The core system employs a frequency-hopping transceiver to combat interference and fading.

The bluetooth is managed by the system of the “Star topology” in many devices are connected they form the piconet there in which all the bluetooth  devices are synchronised , there exists the main server and other clients or we can say the master and the slaves .Let’s take the example of our mobile phones if we want to share our data and files then, the devices which want the data’s is considered as the client and other is called the master or the server. Now let’s go for the internal mechanism of the transfer.

Firstly the master produces the radio frequency shortly known as (RF) of the different range the bandwidth. According to the experiment there are about 79 different kinds of the ISM bands of the RF. Then the clients is tuned to certain frequency is connected to this devices via this RF ,then the data’s and the files can be shared
