1. An ad hoc wireless LAN consists of a group of computers each equipped with a wireless adapter connected via radio signals as an independent wireless LAN Computers in a specific ad hoc wireless LAN must therefore be configured to the same radio channel An ad hoc wireless LAN can be used for a branch office or SOHO operation Ad hoc Wireless LAN Notebook with Wireless USB Adapter AS Notebook with Wireless PC Card 14 CHAPTER 3 NETWORK CONFIGURATION AND PLANNING Infrastructure Wireless LAN The wireless PCI card can also provide access to a wired LAN for wireless workstations An integrated wired and wireless LAN is called an infrastructure configuration A Basic Service Set BSS consists of a group of wireless PC users and an access point that is directly connected to the wired LAN Each wireless PC in this BSS can talk to any computer in its wireless group via a radio link or access other computers or network resources in the wired LAN infrastructure via the access point The infrastructure configuration not only extends the accessibility of wireless PCs to the wired LAN but also doubles the effective wireless transmission range for wireless PCs by passing their signal through one or more access points A wireless infrastructure can be used for access to a central database or for connection between mobile workers as shown in the following figure Wired LAN Extension to Wireless Adapters Wireless Cell2.
