Initial RTT (Round Trip Time)
Round trip time is the elapsed time between a terminal transmission and an access
point acknowledgement. Each terminal continuously adjusts the acceptable round
trip time, calculating the average elapsed time over a number of transmissions. If
an acknowledgement takes longer to receive than the average round trip time
calculated, the terminal will resend the transmission.
Because terminals cannot calculate an average round trip time without a number of
transmissions, a starting point or “Initial Round Trip Time” is required. The terminal
uses the time assigned to the “Initial RTT” parameter as a starting value for round
trip calculations. Once the terminal begins transmitting and receiving data, this
value will be adjusted to reflect the actual average round trip time between transmis-
sions and acknowledgements.
