ProSAFE Wireless Controller WC7600

Manage Load Balancing

Load balancing lets you balance wireless clients over the managed access points of one

model, taking the following aspects into account:

• The maximum number of clients that can connect to the access point model.

• The received signal strength indicator (RSSI) of the wireless clients.

Load Balancing Concepts

Load balancing allows the wireless controller to distribute access point clients (the “load”)

equally among the access points that it manages. You configure load balancing per type of

access point model and per radio. By default, load balancing is disabled.

When a client discovers an access point using probe requests or sends association frames,

the access point determines whether to accept the client based on the number of clients that

are already connected, the signal strength of the clients that are already connected, and the

signal strength of the client that attempts to connect.

The wireless controller performs load balancing based on the following criteria:

• Maximum number of clients. If more than the maximum number of clients that you allow

on a radio of an access point attempt to associate, the clients are pushed to another

access point.

If you want a good distribution of clients between the access points, set the maximum

number of clients to a low value (compared to, for example, the total number of clients in

an office or on a floor).

• Signal strength or RSSI. Signal strength determines speed. For a client that is far away

from an access point, the data rate is much lower than for a client that is in closer

proximity to the access point. The distant client requires more time to transmit or receive

data, and the delay could be too long. You can give a threshold for signal strength, which

is specified as a percentage, from 0 percent to a maximum of 75 percent.

RSSI percentages translate into the following power levels in dBm:

• RSSI of 0% = –95 dBm (load balancing is disabled)

• RSSI of 25% = –81 dBm

• RSSI of 50% = –68 dBm

• RSSI of 75% = –55 dBm

In situations in which the throughput expectation is high, if you want only clients near an

access point to associate with the access point, set the received signal strength indication

(RSSI) to a high percentage. In situations in which the clients can be expected to be far

away or fewer access points are available, set the RSSI to a lower value.

Note: The load-balancing settings apply to all profiles, whether they are in

the basic profile group or in advanced profile groups.
