Concept of Aircards

An aircard is a type of wireless broadband modem used for connecting to cellular networks. Aircards provide roaming access to the Internet from mobile computers outside the range of Wi-Fi hotspots. They may also be used as an alternative to home dial up Internet service in rural areas.

Types of Aircards
Several manufacturers produce wireless network modems including Kyocera, Novatel, Option and Pantech. In recent years, however, the term "aircard" has become associated most closely with the Sierra Wireless AirCard brand of wireless modem products.

Cellular network service providers typically bundle (and sometimes rebrand) compatible wireless modems together with their service contracts. In the U.S., for example, both AT&T and Verizon utilize Sierra Wireless products even though these may be called "AT&T AirCard" and "Verizon AirCard."
