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 11Mb/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. 

LAN bandwidth 

Estimate anticipated peak call volume to ensure that the LAN has 
enough bandwidth available to handle the network traffic generated
