Para que serve as configurações de Beacon Interval...?

Para que ser as configurações de Beacon Interval, RTS Threshold, Fragment Threshold...?


Mudando uma destas configurações consigo um desempenho maior na rede em distâncias maiores?

tambem queria saber isso

Essa é uma dúvida de muitos, já li sobre, mas não tenho convicção pra responder, portanto aguardo as respostas também.

Beacon Interval

Beacon frames are transmitted by an access point at regular intervals to announce the existence of the wireless network. The default behavior is to send a beacon frame once every 100 milliseconds (or 10 per second).
The Beacon Interval value is set in milliseconds.

DTIM Period

The Delivery Traffic Information Map (DTIM) message is an element included in some Beacon frames. It indicates which client stations, currently sleeping in low-power mode, have data buffered on the access point awaiting pick-up.
The DTIM period you specify here indicates how often the clients served by this access point should check for buffered data still on the AP awaiting pickup.
Specify a DTIM period within the given range (1 - 255).
The measurement is in beacons. For example, if you set this to "1" clients will check for buffered data on the AP at every beacon. If you set this to "2", clients will check on every other beacon. If you set this to 10, clients will check on every 10th beacon.
Fragmentation Threshold

Specify a number between 256 and 2,346 to set the frame size threshold in bytes.
The fragmentation threshold is a way of limiting the size of packets (frames) transmitted over the network. If a packet exceeds the fragmentation threshold set here, the fragmentation function will be activated and the packet will be sent as multiple 802.11 frames.
If the packet being transmitted is equal to or less than the threshold, fragmentation will not be used.
Setting the threshold to the largest value (2,346 bytes) effectively disables fragmentation.
Fragmentation involves more overhead both because of the extra work of dividing up and reassembling of frames it requires, and because it increases message traffic on the network. However, fragmentation can help improve network performance and reliability if properly configured.
Sending smaller frames (by using lower fragmentation threshold) may help with some interference problems; for example, with microwave ovens.
By default, fragmentation is off. We recommend not using fragmentation unless you suspect radio interference. The additional headers applied to each fragment increase the overhead on the network and can greatly reduce throughput.
RTS Threshold

The RTS threshold specifies the packet size of a request to send (RTS) transmission. This helps control traffic flow through the access point, especially one with a lot of clients.
If you specify a low threshold value, RTS packets will be sent more frequently. This will consume more bandwidth and reduce the throughput of the packet.
On the other hand, sending more RTS packets can help the network recover from interference or collisions which might occur on a busy network, or on a network experiencing electromagnetic interference.

Muito Bom.
