Site Surveying for Repeater Usage

Repeaters are supported by many of the WLAN products available today. However, the use of repeaters is recommended in only two scenarios:

• Locations where there is no possible way to wire the device

• If the installation will be temporary

The reason for this limited recommended use of repeaters is that a 50-percent reduction of bandwidth is typically introduced. The overlap on a repeater and its wired AP partner has to be, at a minimum, 50 percent. This is required so that the two APs have full communication with each other (see Figure 11-19).
