A wireless modem can be described as a device that is connected to a wireless network rather than a telephone line. Computers that use a wireless modem are linked directly with the wireless internet provider (IP), thus allowing access to the Internet. This type of modem is capable of performing at speeds very similar to those of dialup modems, which is much slower than a broadband Internet connection.

Some of these devices are able to be connected directly to a person's personal data assistant (PDA) or to a notebook computer. Types of available interfaces include:

1. Serial Ports
2. Compact Flash Cards.
3. Universal Serial Bus (USB)
