Abstract: A WiFi / WAPI dual-mode WLAN card circuit design based on mini PCI-E specification is introduced, whose implementation is based on HED05W01SU chip and AL2230S chip, including hardware design, software design and test program.  In the aspect of hardware design, the RF chip interface design, the baseband chip interface design and the mini PCI-E interface design are included.  In the aspect of software design, the driver software and the management software for WLAN card working in Windows OS environment are presented. Based on the GB15629.11 specification, the test program is added for verifying the WLAN card development, and the test results meet the specification requirements. High integration, simple interface, inexpensive and easy to operate is the WLAN card marked properties.
