Broadband Modem Definition
A broadband modem can provide a high-speed Internet connection. It attaches to your computer to provide a connection that can be in the form of a DSL, cable or wireless modem. Because of its high speed and reliability, it is preferred over dial-up connection. It also gives you the ability to perform a number of downloads and uploads in a short period of time.

Function
-
A broadband modem can supply Internet connections up to 10 Mbps. This speed can fluctuate depending on where you live or the number of people sharing the connection. Most companies limit the number of downloads users can perform, as this slows down the network. In addition, if the service provider is experiencing trouble with its network, your broadband modem may not function properly or you may not receive a connection at all.
Types
-
The three major types of broadband modems are DSL, cable and wireless. A DSL modem is one of the fastest broadband modems. It uses an existing phone line to transmit signals, so it interferes with your telephone connection. Most users install a filter so they can use the phone line and the DSL connection simultaneously. A cable broadband modem acquires a connection using a pay-TV connection to transmit signals. To receive this connection, cable lines are installed at your home address. Most users do not like this type of broadband modem because it requires cable wires, and those who live in apartments must receive approval for installation. A wireless broadband modem receives a connection like DSL and cable, but the connection is wireless and doesn't require cables. The wireless connection is usually provided by satellite and mobile networks.

Features
-
Broadband modems can use an Ethernet connection or a USB connection. Many users choose an Ethernet connection because it has proven to be more reliable. If your computer is networked to another computer using a broadband modem with an Ethernet connection, you can receive a stronger connection and transfer information or files from one computer to another. Ethernet connections usually require additional cabling, which can be more expensive and take up additional space. A broadband modem using a USB connection can be slower, and if you are using other USB peripherals, such as a printer, they can interfere with your broadband modem.
Misconceptions
-
Many believe that to set up a broadband modem, one must have extensive computer experience. Some service providers are including free home set-up with their services. An instruction manual is provided, along with customer service telephone support to help you set up your modem. Some will send a technician to your home at an affordable rate to set up your broadband modem.
Warning
-
If you use a broadband modem, activate your firewall. When using broadband modem services, you are on a shared network, and thus others have the ability to see your network if it is not protected. Many people also choose to use a router to secure their network. The service provider can advise you the best way to protect your computer when using a broadband modem.
