Bluetooth technology help us to connect device each other

Bluetooth Technology

 Bluetooth
 could be a short-range wireless technology that allows you to connect computers, mobile phones, and hand-held devices to every different while not without cable.

 Bluetooth uses frequency hopping in time slots except for frequency-hopping, Bluetooth uses a fast acknowledgement to confirm a more robust  communication link, and it dodge the interference caused by annunciation   by merely moving on from one frequency to a different. it always hops quicker and uses shorter packages to avoid the impact of disturbances. Bluetooth works at 2 levels of power, a lower level of power that may cover a smaller space, like that of a room, and a better level of power, that covers a bigger space, like inside a home. Every microchip features a integral set of safety controls and identity codes that may be predetermined and used solely by the owner of the Bluetooth-enabled gadget. Nowadays  Bluetooth  technology  is be used  in phones and pagers, modems, LAN access devices ,headsets, notebook  ,tablet , desktop and hand-held computers, printers, fax machines, keyboards and joysticks

What is Bluetooth models

  Model :Description
 File Transfer :Refers to object transfer or transfer of files between devices.
 Internet Bridge : During this model, a cordless electronic equipment acts as a modem to a                  computer  and serve  dial-up networking and faxing facilities.
 LAN Access : Multiple data terminals use a LAN access point (LAP) as a  wireless                 associate an local area network Ethernet.
Synchronize : The synchronization model allows  authenticate of data between a  device to device                              
Headset :  It's wireless connected and might act as an audio input-  output interface  of  control  devices.


           Every technology have weakness and advantages. For  Bluetooth technology benefits is Bluetooth does not need any configuration to be set for beginning a connection and transfer data between devices. It eliminates the necessity of using  any wires or cables. Bluetooth technology uses a safe connection between devices having a password lock once sharing data between devices. A user can need to enter the password initial  for sharing files and also the alternative user who can receive files also will need to enter an equivalent password.

           Bluetooth technology functions below one hundred meters of distance, that produces the method of data sharing simple and quick.By contrast disadvantages of Bluetooth technology is that this  technology can't be used for web connections because of its restricted  transfer rate. Since Bluetooth technology produce  larger range and data lines frequency, it  get a lot of  exposed to attacks as an example interceptions and sound. As long as new versions area unit returning, you don’t ought to worry regarding now.
          Bluetooth technology drains battery life, and this principally happens once you  use it on your mobile  phones.  It consumes great amount of battery life in  short period of your time and if anyone leaves it   switched  ON for a good quantity  of time,  the battery life are going to be dead in no time. thus you can’t keep switched  ON forever. Security is vital that why Bluetooth Security is introduced .It Bluetooth users will establish "trusted devices" which will exchange data while not asking permission. Once the other device tries to determine a connection to the user's gadget, the user must arrange to enable it. Service-level security and device-level security work along to shield Bluetooth devices from unauthorized data transmission.
         Security strategies embody authorization and identification procedures that limit the use of Bluetooth services to the registered user and need that users create a aware call to open a file or settle for a knowledge transfer.
