Will a Wireless Phone Jack Work With DSL?
As technology advances, the number of devices that don't need wires increases. The term "wireless phone jack," though, can be slightly misleading, as it still needs the electrical wiring in your home to work. A wireless phone jack will not work with a digital subscriber line. However, most DSL providers offer a wireless modem that allows Internet connections throughout the house.

The often misused term "wireless" technically applies to devices that carry signals through the air using radio frequencies. It covers a wide range of devices from cellphones to computer connections in a coffee shop. A link to a satellite for TV service is technically a wireless connection, along with an industrial microwave radio system that carries thousands of telephone lines between two cities. A cellphone company may define their email services as "wireless," but it also provides wireless voice service. A wireless phone jack does not send signals through the air.

Wireless phone jacks come in sets with a base unit and one or more extension units. Plug the base unit into any wall socket and use a standard RJ11 cord to connect a phone line to it. The base unit sends the telephone signals over the house electrical wiring, so you can plug an extension unit into any wall socket to provide a telephone jack at that location. If the line carries DSL, though, you must place a filter between the base unit and its phone line connection to remove the DSL signal. The system will not carry DSL.

Uses
-
Wireless phone jacks extend your telephone line to any location in the house that has a electrical outlet plug. Many people use them to connect a phone line to a TV cable or satellite receiver that uses a telephone connection for ordering additional services by automatic dialing to the main office. It avoids having to run a phone extension cord to the entertainment system. Wireless phone jacks also work for analog fax machines and dial-up computer modems, but not for the digital signals that must pass over DSL.

If you have DSL in your home, you can easily install a modem that includes a wireless router. You should already have a filter into the phone line to separate the digital computer and the analog phone signals coming from your service provider. Simply remove your old modem form the digital side of the filter and plug the wireless router in its place. It will send Internet signals through most of your house, and you can connect to the Internet using a computer with a wireless card installed. Call your DSL service provider for details.
