Access Point Capacity and Positioning

Each site is unique in its AP requirements. Therefore, 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 WLAN coverage wherever the SpectraLink 8000 Wireless Telephones will be used. Adequate coverage for a SpectraLink 8000 Wireless Telephone can be determined by using the Site Survey mode on the handset that displays dBm signal levels and channel when the handset is in range of an AP.

For setting up the data rates, please consult your facility’s RF site survey, designed for voice traffic, to determine if you have sufficient coverage to support all data rates. SpectraLink 8000 Wireless Telephones require the following minimum dBm reading to support the corresponding “Required” data rate setting in the access point.

All SpectraLink 8000 Wireless Telephones on the WLAN network must be configured for a single radio standard (802.11a, or 802.11b, or 802.11g). Handsets configured for different radio standards will not work together.

Number of handset calls per AP

The number of handsets that can be in-call simultaneously was determined based on call quality within a lab environment. Since call quality is impacted by packet retry rate and missed packets, test criteria were established for the maximum data rate (11Mb/s) for handsets in-range of the AP.

As the handsets move near the limits of optimal RF coverage from the AP, they will automatically drop to lower Mb/s operation. SpectraLink 8000 Wireless Telephones require approximately 15 % of
