According to its technical definition, Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices, and building Personal Area Networks (PANs).
For an android smartphone user, you may follow these simple steps below to activate and use the Bluetooth technology on your device:
Step 1. Go to your phone and select settings
Step 2. Select the Bluetooth icon/label
Step 3. Tap on the switch icon to activate Bluetooth from “Off” to “On”
Step 4. You will now be able to see the various or available Bluetooth devices where you can initiate a “hand-shake” (connection).
In almost all phones produced today either a smart phone or a feature phone, Bluetooth is an “in built” wireless technology tool which has the following benefits when using:
➨It creates ad hoc connection immediately without any wires. Connection establishment is very quick. User only need to pair the Bluetooth PAN (Personal Area Network) connection between two devices.
➨It has low power consumption.
➨It can pass through walls.
➨It has range better than Infrared communication.
➨It has been managed by Bluetooth SIG (Special Interest Group) and hence, products from large companies are available and there is no issue of interoperability among different blue tooth vendor products.
➨It is used for voice and data transfer.
➨It uses FHSS (Frequency Hopping Spread Spectrum) and hence, data communication is more secure.
➨The technology is adopted in many products such as head set, in car system, printer, web cam, GPS system, keyboard and mouse.
➨Due to availability of Bluetooth headphones, calls can be taken on phone even while driving and doing some other activity simultaneously. This hands free operation relieves great strain.
➨Bluetooth devices are available at very cheap cost.
➨It has less interference compare to other wireless technologies due to use of FHSS (Frequency Hopping Spread Spectrum) technique.
