4.0 Configuration
The Wireless Distance parameter allows a user to set the expected
distance the WiFi signal needs to travel. The default is 100m, so the
BulletPlus will assume that the signal may need to travel up to 100m
so it sets various internal timeouts to account for this travel time.
Longer distances will require a higher setting, and shorter distances
may perform better if the setting is reduced.
Once the RTS Threshold defined packet size is reached, the system
will invoke RTS/CTS flow control. A large RTS Threshold will improve
bandwidth, while a smaller RTS Threshold will help the system recover
from interference or collisions caused by obstructions.
The Fragmentation Threshold allows the system to change the
maximum RF packet size. Increasing the RF packet size reduces the
need to break packets into smaller fragments.
fragmentation threshold slightly may improve performance if a high
packet error rate is experienced.
The Clear Channel Assessment uses carrier sense and energy
detection to determine if a channel/medium is available for
transmission. Changing the threshold will impact how the BulletPlus
Wifi determines channel availability.
