Method of repeating data transmission between network devices by timing a first predetermined period after previous first data transmission

A method of transmitting data from a transmitting device, comprising:

• transmitting a first data frame to a receiving device a first time, using an immediate acknowledgement policy;
• consecutively transmitting the first data frame to the receiving device second through (N−1)th times, using an immediate acknowledgement policy, each of second through (N−1)th first data frame transmissions being made a first predetermined time period after a respective previous first data frame transmission;
• transmitting the first data frame to the receiving device an Nth time, using a no acknowledgement policy, the Nth first data frame transmissions being made a first predetermined time period after the (N−1)th first data frame transmission;
• and
• transmitting a second data frame to the receiving device, using an immediate acknowledgement policy, a second predetermined time period after the Nth first data frame transmission,
• wherein N is an integer greater than 1, and
• wherein the second predetermined time period is less than the first predetermined time period.
