Abstract
A wireless LAN card to be connected to a portable computer having a main body with a PCMCIA socket, includes a wireless transmission board including a wireless sending/receiving part to modulate and demodulate packet of a specific frequency modulation range and to wirelessly send and receive data; and a wireless LAN board including a controller to sense whether or not the wireless transmission board is connected to the wireless LAN board, to convert the data received through the PCMCIA socket into the packet data, and to transmit the packet data to the wireless transmission board. With this configuration, a wireless LAN card and a operation of controlling the same is provided, in which the wireless LAN card is usable as a memory card and a wireless sending/receiving part thereof is easily replaceable for one of a desired specification.
