History Nokia and Symbol Technologies in 1999 created an association known as WECA (Wireless Ethernet Compatibility Alliance Wireless Ethernet Compatibility Alliance). This partnership became known as Wi-Fi Alliance in 2003. The purpose of the meeting was to create a brand that would allow more easily promote wireless technology and ensure compatibility of equipment. Thus in April 2000, WECA certifies interoperability of equipment according to the IEEE 802.11b standard under the brand Wi-Fi. Jason Konior This means that the user has the guarantee that all computers that have Wi-Fi seal can work together seamlessly, regardless of the manufacturer of each of them. You can obtain a full list of teams that are certified Wi-Fi Alliance - Certified Products. In 2002 the association WECA was formed and almost 150 members in its entirety. The IEEE 802.11 standard was designed to replace the equivalent physical and MAC layers of the standard 802.3 (Ethernet).This means that the only thing that differs a Wi-Fi to an Ethernet network is in how they are transmitted frames or data packets, the rest is identical. Therefore, an 802.11 wireless LAN is fully compatible with all the amenities of local networks (LAN) cable 802.3 (Ethernet).
