Write a Short Note on Bluetooth

Write a Short Note on Bluetooth
·        Bluetooth is wireless protocol utilizing for short-range communications and data transmission over the distance from fixed or mobile devices.
·        It is used to create wireless personal area network (PAN).
·        Bluetooth uses a radio technology called frequency hopping spread spectrum.
·        It chops up data being send and transmits by 75 different frequencies.
·        It can achieve gross data rate of transmission mbps and it provides way to connect and exchange information between devices such as mobile phones, telephones and laptops and personal computers and printers.
·        Bluetooth protocols simplify the discovery and setup of services between devices.
·        Bluetooth devices can advertise all of the services they provide.
·        This makes using services easier because more of the security, network address and permission configuration can be automated than with many other network types.
·        This technology is most useful when transferring information between two or more devices that are near each other in low bandwidth situations.
