Very Low—Roaming aggressiveness is very low. The client maintains connection with the current
access point until its RSSI and transmit rate drop to the values where it may loose connection. The
client roams to another access point only when it might loose connection with the current access
point. This roaming policy prioritizes connection to the current AP rather than performance. This
policy is best suited for environments in which only one access point is present.
Low—Roaming aggressiveness is low. The client maintains connection with the current access point
until its RSSI and transmit rate drop to values where performance is heavily degraded. This policy
is best suited for environments in which access points are distributed sparsely.
Normal—Roaming aggressiveness is normal. The client maintains connection with the current
access point until its RSSI and transmit rate drop to values where performance is degraded. This
policy gives balanced priorities to roaming aggressiveness and performance.
High—Roaming aggressiveness is high. The RSSI and rate thresholds are set to high values to
increase the aggressiveness of roaming. This policy is best suited for environments in which many
access points are closely distributed and in which the user moves around at a faster pace.
Very High—Roaming aggressiveness is very high. The RSSI and rate thresholds are set to values
that give the best performance. This policy is best suited for environments in which multiple access
points are present and in which the user can switch to the best performing access points at any time.
Default—The default roaming policy is Normal. This roaming policy is set in the client driver.
