1/22/04 Review Draft—CONFIDENTIAL Overlap Factor The Overlap Factor is the amount of signal area overlap that you want when the APs are operating. Overlap is important if an AP fails. It allows the network to self-heal with adjacent APs powering up to assume some of the load from the failed device. Although there may be no holes in coverage in this scenario, there will likely be a loss of throughput.
1/22/04 Review Draft—CONFIDENTIAL Select the desired data rates from the pull-down menus for 802.11b/g and 802.11a. High data transmission rates will require an increased number of AP to be placed in your building. You should carefully evaluate your user’s data rate needs.
