Setting | Description |
Min Contention | For each access category, enter the minimum |
Window | contention window value. Channel access is |
| prioritized by assigning smaller contention |
| window values to a higher priority traffic class. If a |
| channel is busy or a transmission collides, a node |
| chooses a random number between 0 and the |
| current contention window minimum. |
Max Contention | For each access category, enter the maximum |
Window | contention window value. The minimum |
| contention window value is doubled each time a |
| collision occurs until the maximum is reached. A |
| small contention window value decreases the |
| access delay but increases the probability of a |
| collision. |
Fixed Slot Time | For each access category, enter the fixed slot time. |
| Channel access can be strictly prioritized by |
| assigning smaller contention window values to a |
| higher priority traffic class. Traffic in the access |
| category must wait for this fixed number of slots |
| after each packet is received before resuming its |
| random |
Transmit | Enter the number of microseconds that qualified |
Opportunity Limit | transmitters can transmit through the normal |
| |
| Larger values allow a client to control the channel |
| for longer periods of time, allowing it to achieve |
| higher throughput in this access category at the |
| expense of longer access times for all access |
| categories. |
