Intr oduction Congratulations on choosing o ne of NDC’s I nstantWave Hig h Rate wireless networking product’s family . InstantWave High Rate was one of the first IEEE 802.11b wi reless standard c ompli ant product s in the indust ry and was designed t o maximize the convenien ce of network ing.
Glossar y Group ID / BSSID A Group ID (the 802.1 1 standard uses the term BSSID) is t he ID of a wir eless cell. A wireless cell is usually made up of stations in an area that the radio signal can comfortably cover. In ot her words, any wireless station in the cell can communicat e with any ot her wi thi n reac h of the radi o signal.
Ho w to Use this Guide InstantWave High Rate is ex tremely versatile in provid ing varying levels of network m anagement. Fo r Small Office/Home Offi ce users, setu p and configuration is a quick, four-step pr ocess.
Planning Y our Netw or k Infrastructure Network Types An Infrastructu re network i s formed by several stat ions and o ne or more Access Points (APs), with the stations within a set distance from the AP. Figure 1 depicts a typical Infras tructure netw ork topology .
Server Figure 2. AP to Wire d Ethernet Bridge Type 3. The third typ e of n etwork is co mposed of multiple APs and multiple Stations ( Figure 3 ). The APs could also be connected to serve rs on the wired Ethe rnet network. The shadowed area represents signal overlap bet ween subnet 1 (AP-1) and subnet 2 (AP-3).
Planning an Infrastructure Network This section e xplains som e of the thin gs you need to consider i n planni ng an Infrastructure network. Setting up is a two step process.
