Bluetooth DUN allows wireless internet connectivity to a laptop using a Bluetooth-enabled cell phone. It requires configuring both devices for Bluetooth connectivity and an ISP username and password. Bluetooth DUN supports 1-3 Mbps and instructional videos are available on Bluetooth.com.
Bluetooth® dial-up networking (DUN) refers to obtaining wireless Internet connectivity to a laptop using a Bluetooth®-enabled cell phone. Bluetooth® DUN is a good alternative for wireless Internet when there is no local hotspot or wireless access point to provide faster and more efficient access. At a minimum, it lets you check email or perform other low-bandwidth online tasks.
Bluetooth® is a personal access network (PAN) technology that uses radio waves in the 2.4 gigahertz range to connect personal devices. It is often used to connect cell phones with hands-free headsets, but is also used for communication between personal digital assistants (PDAs) and laptops, cell phones and laptops, mice, keyboards and printers, and even game consoles. Bluetooth® DUN is just one of the many ways Bluetooth® technology enhances personal flexibility in the digital world.
To create a Bluetooth® DUN connection, you must first configure the laptop for Bluetooth® connectivity to be enabled. The mobile phone must also be configured to communicate via Bluetooth®. The laptop should recognize all Bluetooth®-enabled devices in close proximity. Your mobile phone is selected as the device of choice and the first time you connect you need to set up a Bluetooth® DUN shortcut. In this step, the laptop is configured to communicate using the Bluetooth® modem instead of the standard internal modem.
When configuring a Bluetooth® DUN, an Internet Service Provider (ISP) username and password are required, as well as a telephone number for dial-up access. If the Bluetooth® connection is encrypted, the user may also need to enter a Bluetooth® security code into both their mobile phone and laptop. This will allow the devices to successfully “shake hands” or form a connection.
Once a Bluetooth® DUN shortcut has been created on the laptop, the user can click it at any time to use the mobile phone to dial an access number. Online speed varies depending on various factors, but Bluetooth® supports one to three megabits per second (mbps), depending on the Bluetooth® specification used. To put this in perspective, a basic Digital Subscriber Line (DSL) service transfers data at about 100 Mbps.
Because different cell phones and laptops have different navigation steps for pairing Bluetooth® devices and creating a Bluetooth® DUN, Bluetooth.com has created instructional videos. By clicking Connect Devices from their home page, the Bluetooth® enthusiast can find specific videos for pairing devices. If your phone model is not listed, there are also generic instructions for setting up a Bluetooth® DUN.
