ProSAFE Wireless Controller Setting Description TXOP Limit Specify the transmission opportunity (TXOP) limit. Note: Station EDCA parameters only The TXOP limit applies only to station AP EDCA parameters and specifies the maximum period during which the client station client can initiate transmissions. The following are the default values for the Station EDCA parameters: • Data 0 (Best Effort). 0 • Data 1 (Background). 0 • Data 2 (Video). 3008 • Data 3 (Voice). 1504 8. Click the Apply button.

Manage Load Balancing Load balancing lets you balance WiFi 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 WiFi 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. Configure WiFi and QoS Settings 210

Manage Load Balancing

Load balancing lets you balance WiFi 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 WiFi 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.

TXOP Limit

Note:

Station EDCA

parameters only

Specify the transmission opportunity (TXOP) limit.

The TXOP limit applies only to station AP EDCA parameters and specifies the

maximum period during which the client station client can initiate transmissions.

The following are the default values for the Station EDCA parameters:

•

Data 0 (Best Effort)

•

Data 1 (Background)

•

Data 2 (Video)

3008

•

Data 3 (Voice)
