The minimum configuration required is the Extended Service Set Identifier ESSID of the WLAN or test AP and the WEP keys if applicable AP requirement considerations Each site is unique in its AP requirements Consider the following points when determining how many APs are needed and where they should be placed e Minimum Radio Signal Strength All APs in the coverage area must receive a signal strength better than 70 dbm Measurement is made in negative dbm which measure the amount of signal loss due to distance Therefore stronger signals are those with smaller values For example 50 and 60 indicate stronger signals than 70 80 is a weaker poorer signal than 70 e Adjacent APs and channel interference In order to avoid undesirable interference from adjacent APs ensure that adjacent APs do not use channels that overlap on the same frequencies Figure 1 shows the frequencies used by each channel In the figure channels on the same horizontal line do not overlap In the coverage area of any given AP signals from other APs using overlapping channels should be at least 15 to 20 dbm weaker Because the Site Survey mode displays signals only from APs on the same Extended Service Set ID ESSID check for signals from APs using all ESSIDs to avoid channel overlap NN40010 303 Chapter 3 Planning 27 Figure 1 Frequencies used by each channel Frequency Wireless handset range Wireless LAN cove
