This publication describes techniques for determining a data rate at which an electronic device on a wireless local area network should transmit to another wireless local area network device. The electronic device conducts a data rate search by transmitting multiple short packets, or probes, each at a different rate over a trial period to determine a data rate for future transmissions. The packets are transmitted one after the other to the access point and may or may not carry meaningful data. The data rate search can be further informed by a transmission history of the electronic device, smart search algorithms, searching multiple input/multiple output (MIMO) streams, searching guard intervals, and searching across multiple bands. A candidate set of data rates can be tried multiple times to get accurate estimates for the data rates before a data rate is selected for transmission.
