A modem and antenna that transmits and receives over the air. Wireless modems support several technologies, including 802.11, Bluetooth, CDPD, DataTAC, Mobitex and Ricochet. There are wireless modems for laptops, handhelds and cellphones. Except for a few analog cellphone models, you cannot plug your cellphone into your laptop's land-based modem even if the cable fits. You generally need a wireless modem on a PC card and a cable designed for your type of phone. See wireless glossary.
