Access Point Capacity and Positioning
Each site is unique in its AP requirements. Please take the following points into account when determining how many APs are needed and where they should be placed in the facility.
Handset range
There must be wireless LAN coverage wherever SpectraLink 8000 Wireless Telephones will be used. The typical range for a SpectraLink 8000 Wireless Telephone is comparable to that of a laptop computer utilizing a wireless LAN PC card. However, SpectraLink 8000 Wireless Telephones are likely to be used in areas where data devices are not typically used, such as stairwells and outdoor areas. SpectraLink 8000 Wireless Telephones have a Site Survey mode that displays dBm levels to determine adequate WLAN coverage. Refer to the Administration Guide for your SpectraLink Wireless Telephones for details about this feature.
Number of handsets per access point
Estimate the number of SpectraLink 8000 Wireless Telephones and their anticipated call volume per AP area to ensure that the maximum number of calls per AP will not be exceeded. In this estimate, consider the data rates at which the handsets will operate. Higher data rates can only be sustained while well within the range of the AP. If the SpectraLink 8000 Wireless Telephones will be operating near the limits of the RF coverage from the AP, they will automatically drop to 1 Mb/s operation. SpectraLink 8000 Wireless Telephones require approximately 15% of the available bandwidth per call for 1 Mb/s operation, approximately 10% of the available bandwidth per call for 2 Mb/s operation, approximately 7% of the available bandwidth per call for 5.5 Mb/s operation, and approximately 5% of the available bandwidth per call for 11 Mb/s operation.
The maximum number of telephone calls per AP quoted in the summary table above is based on 11 Mb/s operation, and will be reduced if some or all SpectraLink 8000 Wireless Telephones are operating at 1, 2, or 5.5 Mb/s.
