Chapter 5 Compliance : Configuring FortiGate units for PCI DSS compliance : Network topology : The CDE wireless LAN
  
The CDE wireless LAN
Wireless networking is a special issue. Even if you do not use wireless technology you must monitor to ensure that unauthorized wireless access has not been added to the CDE network. For this purpose, Figure 154 shows a FortiAP device in the CDE. The FortiAP device can provide dedicated wireless monitoring, an access point, or both.
A small retail outlet could reduce costs by using a FortiWiFi unit, a FortiGate unit with integrated wireless networking. The FortiWiFi unit would have to be located where it could provide sufficient wireless monitoring (or access point) coverage for the entire premises.
