A manufacturer can use the WiFi logo on a new product only after strict prod- uct testing to demonstrate compatibility with standards and with previously manufactured units. Interoperability is thus ensured, so that Nokia and Cisco products can “talk” to Lucent and Dell network cards, and vice versa. The 802.11 standard defines the in- frastructure mode and the ad hoc mode. The infrastructure mode (Figure 1) in- volves at least one access point (AP) that is connected to the wired network infra- structure, along with a set of wireless end stations. This connection type is used in airports, cafes and other public places. The configuration is called a Basic Service Set (BSS). An Extended Service Set (ESS), by comparison, in- volves a set of two or more BSSs, thus forming a single sub-networks. Most so- phisticated access point models can al- Figure 1.
