The ongoing acceptance of Wi-Fi certification by a broad range of companies reinforces it as the single wireless LAN standard for the home, small office, enterprise and public access areas. There are currently 93 Wi-Fi certified products from 38 companies.
Companies seeking product certification represent a broad range of interests.
Some of these certifications are coming from companies seeking their first Wi-Fi certification. The Wi-Fi logo is significant in that it certifies interoperability between PC wireless LAN cards, devices and access points from different vendors. Testing usually takes two to four days per product to complete. WECA has defined a test suite that defines how member products are tested to certify that they are interoperable with other Wi-Fi certified products. This testing assures that products bearing the Wi-Fi logo will work with each other.
