coverage

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.

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.
