What is a PCMCIA Wireless Card?

PCMCIA cards let you connect to wireless Internet hotspots.

A PCMCIA wireless card can add a whole new dimension to your laptop: wireless networking. Most people, however, do not need a wireless card because manufacturers include an internal wireless card as a standard feature.

Identification

PCMCIA is an abbreviation for Personal Computer Memory Card International Association. Most people prefer to use to more common term "PC card." Wireless PCMCIA cards contain an antenna that communicates with wireless access points.

Significance

Wireless cards are most beneficial on older laptops that do not have internal Wi-Fi or if your internal wireless card breaks, according to CNet. You also might want one to upgrade to the latest wireless standard--802.11n as of 2010.

Free Wi-Fi Hot Spots

You can use your wireless PCMCIA card to connect to free Wi-Fi hot spots at public places such as coffee houses and libraries, according to PC Magazine. If you want to start home networking, you need a wireless router.
