The number of access point units in a set area determines the network coverage for that area. A great number of access point
units covering a small area would be a high-density cell. Few access point units, or even a single unit covering the same small
area would result in a low-density cell, even though in both cases the actual area did not change- only the number of access
points covering the area changed.
In a typical office, smalls cells may have a 3 meter (10 ft.) diameter and an WL520 device every 6 m (20 ft.), which would be
considered high density. In contrast, large cells in a typical warehouse may have a 27.5 meter (90 ft.) diameter and an WL520
unit every 60 m (200 ft.), considered low density.

1. From the Web interface, click the Configure Configure Configure Configure button, and select the Network Network Network Network tab.
2. Select the Interfaces Interfaces Interfaces Interfaces sub-tab.
3. Select the Wireless Slot Wireless Slot Wireless Slot Wireless Slot tab that corresponds to an 802.11b card.
4. Use the drop-down menu to set the Distance Between APs for the appropriate card. The WL520 recognizes the
following five values for the Distance Between APs parameter (configurable for each Wireless NIC): Large, Medium,
Small, Minicell, and Microcell.
CAUTION: !
The distance between APs should not be approximated. It is calculated by means of a manual Site Survey, in which
an WL520 unit is set up and clients are tested throughout the area to determine signal strength and coverage, and
local limits such as physical interference are investigated.
From these measurements the appropriate cell size and density is determined, and the optimum distance between APs
is calculated to suit your particular business requirements.
