Chapter 2: Network Configuration andPlanningNetwork TopologyWireless LAN Basic5An Ad-Hoc wireless LAN is a group of computers, each equipped with one WLAN adapter,connected as an independent wireless LAN. Computers in a specific Ad-Hoc wireless LAN must beconfigured to share the same radio channel.Fig 2-1 Ad-Hoc Wireless LANNotebook with PCMCIA WLAN CardNotebook with PCMCIA WLAN CardDesktop with USB WLAN AdapterThe adapter supports legacy Ethernet LAN network configuration options as defined by theIEEE 802.11b standards committee.The adapter can be configured as: Ad-Hoc for departmental or SOHO LANs. Infrastructure for enterprise LANs. LAN-Interconnection for point-to-point link as campus backbone.
6The adapter provides access to a wired LAN for wireless workstations. An integrated wirelessand wired LAN is called an infrastructure configuration. A group of adapter PC users and an AccessPoint compose a Basic Service Set (BSS). Each adapter PC in a BSS can talk to any computer inthe wired LAN infrastructure via the Access Point.An infrastructure configuration extends the accessibility of a adapter equipped PC to a wiredLAN, and doubles the effective wireless transmission range for 2 adapter PCs. Since the AccessPoint is able to forward data within its BSS, the effective transmission range in an infrastructure LANis double.The use of a unique ID in a BSS is essential. All adapter equipped PCs configured withoutroaming options in independent BSS must be configured with a BSS ID corresponding to the AccessPoint used in the BSS. Check your Access Point for its BSS ID or use the Access Point BrowserUtility program to determine the BSS IDThe infrastructure wireless LAN configuration is appropriate for enterprise-scale wirelessaccess to a central database, or as a wireless application for mobile users.Fig 2-2 Infrastructure Wireless LANNotebook with PCMCIA WLAN CardDesktop with USB WLAN AdapterAccess Point 1Access Point 2Server Desktop PCFig 2-3 The effective transmission range
RoamingInfrastructure mode also supports roaming capabilities for mobile users. More than one BSScan be configured as an Extended Service Set (ESS). The continuous network allows users to roamfreely within an ESS. All adapter PCs and Access Point within one ESS must be configured with thesame ESS ID.Before enabling an ESS with roaming capability, it is recommended to select a feasible radiochannel and optimum Access Point position. Proper Access Point positioning combined with a clearradio signal will greatly enhance performance.Fig 2-4 Roaming in an Extended Service Set (ESS)Access Point 1Access Point 2Notebook INotebook IBSS1 BSS2ESSUSB WLAN AdapterUSB WLAN AdapterServer Desktop PC7
