Tethering is the process of connecting a computer to the Internet using a cellular phone as a modem. Using tethering, you can access the Internet on a computer in locations where you wouldn't normally be able to connect. If there's no Wi-Fi nearby, it's no problem. Some carriers charge more for tethering service, so you may need an extra data feature added to your plan.
USB Data Cable
Connecting to the Internet via USB data cable is the oldest type of tethering. The data cable plugs into the data or charging port on your phone, and the other end plugs into the computer's USB port. This type of tethering has the advantage of charging your cell phone off your computer's battery while you are connected to the Internet. As long as your computer's battery has power, your phone's battery will not die while you are connected. In order to connect, you will need modem drivers. Most cellular manufacturers offer free drivers. You can download the drivers off the manufacturer's web site.
Bluetooth
Bluetooth is a wireless protocol. Most people are familiar with Bluetooth headsets, but it can also be used for connecting to the Internet via a cell phone. To connect, both the phone and the computer must have Bluetooth capabilities. All modern cell phones support Bluetooth, but not all computers do. If your computer does not have built-in Bluetooth support, you will need to purchase a Bluetooth adapter that plugs into the computer's USB port. Bluetooth USB adapters are not expensive. Whether you have built-in Bluetooth or use a Bluetooth adapter, you must go through a Bluetooth pairing process to connect the phone to the PC.
Wi-Fi
Some newer model smartphones have the capability of transmitting and receiving a Wi-Fi signal. With special software you install on your phone, you can tether the computer through the phone's Wi-Fi connection. The phone acts just like a Wi-Fi hotspot, except the Internet connection is through the phone's cellular Internet. You can even set up access keys and security, to keep others from mooching off your phone's Internet connection. Since most cellular carriers charge extra for going over your data allowance, it's definitely a good idea to keep others off your phone's Wi-Fi.
Tethering Software
USB and Bluetooth tethering connections use dial-up-networking to connect the computer to the Internet. Instead of setting up all the connections yourself, some carriers provide free connection software that installs all the necessary software and creates the connections for you. Some of them also offer other features, such as being able to track the amount of data you've used so you don't go over your data allowance. Check on your cellular carrier's website to see if it offers connection software. If you have trouble with the software, contact your carrier's tech support department.
