What is Bluetooth Wireless Technology?

By | 8th November 2015

 Bluetooth Wireless Technology

Bluetooth technology uses radio transmissions to enable devices such as computers, printers, mice, or mobile phones to communicate wirelessly over a short distance. Bluetooth was invented in 1994 by the Ericsson mobile phone company of Sweden. The bluetooth standard was released  in 1999 and is now widely used by mobile phone and computer companies, including IBM, Nokia, 3Com, Intel etc

Bluetooth provides economical and low power communication method that helps conserve a mobile device battery’s power. WI-FI and bluetooth has been proven to coexist on a home network, we will look at how to install and configure bluetooth on home devices.

 Some of the ways to use Bluetooth technology are:

·   To transfer files between computers or between a computer and another device
·    To print using a Bluetooth enabled wireless printer
·    To use a Bluetooth enabled wireless keyboard or mouse
·    To listen to music using Bluetooth enabled wireless headphones
·    To synchronize a Bluetooth enabled personal digital assistant (PDA) to a computer or another device
·         To create a wireless connection to the Internet with a Bluetooth enabled mobile phone or a modem server
·   To join a Bluetooth personal area network (PAN)





How To Set up a Bluetooth Enabled Device

To set up a Bluetooth enabled device, you need to do three things:

1.      Add a Bluetooth adapter to your computer.

This is usually done by plugging the adapter into a USB port. (If a Bluetooth adapter is already built in or attached to your computer, ignore this step.)

2.      Set up the device so that your computer can find it.

To do this, you must:

o        Turn the device on.

o        Make it discoverable.

To learn how to make a device discoverable, check the information that came with your device or go to the manufacturer’s website.

3.      Install the device.

To install most devices, such as a mobile phone, keyboard, mouse, or personal digital assistant (PDA), you can use Bluetooth Devices in Control Panel. If you have Bluetooth wireless technology installed on your computer, follow these steps:

To install a Bluetooth Enabled Device
1.     Click the Start button
2.      Select and click Control Panel
3.      Click Hardware and Sound, and then click Bluetooth Devices.
4.      Click Add, and then follow the instructions.

To install a Bluetooth Enabled Printer

To install a bluetooth enable printer follow this steps:
·         Click Start
·         Click Control Panel
·         Click Hardware and Sound
·         Click Add a Printer
·         Click Add a network, wireless or bluetooth printer
allow some time for the wizard to detect your printer and follow the recommended steps depending on the type of operating system.
Note
·         Encryption features and a passkey can help to secure your data. However, these and other security measures can be compromised or fail and, if that happens, your data could be visible to or accessible by other devices or computers within range. Therefore, Bluetooth wireless technology should not be considered completely secure.




Find Bluetooth Enabled Devices Near You
If you have Bluetooth wireless technology installed on your computer and you want to find devices near you, open Bluetooth Devices in Control Panel. Here’s how:

·       Click the Start button ,
·         Click Control Panel,
·         Click Hardware and Sound, and then Click Bluetooth Devices.
Any nearby devices will be listed on the Devices tab.

Choose a COM port for a Bluetooth Enabled Device
Some computer programs require a COM port (also called a serial port) to communicate with a Bluetooth enabled device. For example:

·       A program that synchronizes contacts with a mobile phone
·         A program that extracts Global Positioning System (GPS) coordinates from a GPS receiver
When you use the Add Bluetooth Device Wizard to add a Bluetooth enabled device to your computer, you create an incoming COM port, which permits your device to connect to a program on your computer, and an outgoing COM port, which permits a program on your computer to connect to your device. Usually, you only need to use one of these COM ports.

To decide which COM port to use, you can check the information that came with the program or your Bluetooth enabled device, or go to the manufacturer’s website.

If you’re still not sure which COM port to use, try each COM port, one at a time, and use the one that successfully allows the program and your device to communicate.

Change settings for a Bluetooth Enabled Device
If you have a device that uses Bluetooth wireless technology, here’s how to change its name, enable or disable services for it, and control connection settings.

You must have Bluetooth wireless technology installed on your computer to complete these steps.

1.     Click the Start button ,
2.       Click Control Panel
3.      Click Hardware and Sound, and then click Bluetooth Devices.
4.      Click the device that you want to change, and then click Properties.

Note:
*       To help protect your computer, only make your computer discoverable when you want a Bluetooth enabled device to find your computer.




Using passkeys for Bluetooth Enabled Devices
Here are answers to some common questions about using passkeys for Bluetooth enabled devices.

 What is a Passkey?
A passkey (sometimes called a passcode) is a number that associates your computer with a Bluetooth enabled device. For security reasons, most Bluetooth enabled devices (with some exceptions, such as mice) require you to use a passkey. Using a passkey helps ensure that your computer is connecting to the device that you intended and not someone else’s device that is nearby.

 What does “exchanging passkeys” mean?
Exchanging passkeys, also known as association or pairing, means getting a device to recognize your computer or another Bluetooth enabled device. With some devices, you do this by running the Add Bluetooth Device Wizard and typing in your passkey when prompted. Other devices require a different method. For more information, check the instructions that came with the device.

The purpose of the passkey exchange is for Windows to positively identify the device that you want to connect to.

Note:
·         Your Bluetooth device might be less secure if you use a short passkey. If you have a choice, use a longer passkey of up to 16 characters. Also, for security reasons, do not retype your passkey more often than necessary, particularly in public places where a hacker could be “eavesdropping” on your Bluetooth device.

 Where do I get a Passkey?
If a passkey is listed in the documentation for your device, use that one. If not, and if you have Bluetooth wireless technology installed on your computer, the Add Bluetooth Device Wizard can automatically generate a passkey for you or you can create one of your own. To start the wizard, follow these steps:

1.    Click the Start button
2.      Click Control Panel
3.      Click Hardware and Sound, and then click Bluetooth Devices.
If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

4.      Click Add, and then follow the instructions.

Note
·         Encryption features and a passkey can help to secure your data. However, these and other security measures can be compromised or fail and, if that happens, your data could be visible to or accessible by other devices or computers within range. Therefore, Bluetooth wireless technology should not be considered completely secure.

Connect to a Bluetooth Personal Area Network (PAN)
When you connect to a Bluetooth personal area network (PAN), you gain access to all Bluetooth enabled devices and computers that are part of the PAN. This is easier than connecting to multiple devices or computers individually. Connecting to a PAN automatically creates a TCP/IP connection between your computer and Bluetooth enabled devices or other computers. For example, you could use a PAN to connect to another computer to share files or play games.

1.    Click start
2.      Click control Panel
3.      Click Manage Network Connections.
4.      Under Personal Area Network, click the Bluetooth Network Connection icon.
5.      On the toolbar, click View Bluetooth network devices.
6.      In the Bluetooth Personal Area Network Devices dialog box, under Bluetooth devices, click the device that you want to connect to, and then click Connect.

If the device you are looking for isn’t listed, it might not support PAN services. If you are sure that it supports PAN services, try reinstalling the device by following the steps in Set up a Bluetooth enabled device.

Connect to the Internet using a Bluetooth Enabled Mobile Phone
You might be able to use a Bluetooth enabled mobile phone to connect your computer to the Internet. First, check the information that came with your phone to see if it can be used as a modem. If it can, follow these steps to set it up:

Note
·         Before following these steps, make sure your phone has exchanged passkeys with your computer. For more information, see above Set up a Bluetooth enabled device.

1.     Click Start Button
2.      Click Connect to
3.      Click Set up a Connection or network
4.      Click  the Connect to the Internet wizard.
5.      If you already have an Internet connection, click Set up a new connection anyway.
6.      If the Do you want to use a connection that you already have? page appears, click No, create a new connection.

4.      On the How do you want to connect? page, click Dial-up, and then follow the steps. Make sure you select the Bluetooth enabled modem (your phone).

5.      On the Type the information from your Internet service provider (ISP) page, in Dial-up phone number, type the carrier code or phone number.

Contact your mobile service provider for the required ID (or user name), password, and carrier code or phone number.
