Interfaces

Cell capacities are compared in the following table, which shows that small cells suit most offices and large cells suit most warehouses:

Coverage

The number of Access Points in a set area determines the network coverage for that area. A large number of Access Points covering a small

area is a high-density cell. A few Access Points, 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, a high density area consists of a number of Access Points installed every 20 feet and each Access Point generates a small

radio cell with a diameter of about 10 feet. In contrast, a typical warehouse might have a low density area consisting of large cells (with a

diameter of about 90 feet) and Access Points installed every 200 feet.

Wireless Distribution System (WDS)

A Wireless Distribution System (WDS) creates a link between two 802.11a, 802.11b, or 802.11b/g APs over their radio interfaces. This link

relays traffic from one AP that does not have Ethernet connectivity to a second AP that has Ethernet connectivity. WDS allows you to

configure up to six (6) ports per radio

In the WDS example below, AP 1 and AP 2 communicate over a WDS link (represented by the blue line). This link provides Client 1 with

access to network resources even though AP 1 is not directly connected to the Ethernet network. Packets destined for or sent by the client

are relayed between the Access Points over the WDS link.
