Abstract: An automatic modulation mode selecting unit (208) and a method (100) provide for selection from a plurality of modulation modes having an optimized transmission time for a data file. This is particularly useful where a small data file is to be transmitted, such as for a hand-held message pad. The present invention may select a modulation mode having a slow data rate but a short training time to achieve a shorter transmission time a small data file in comparison with using another modulation mode having a fast data rate but a longer training time, and thus a longer transmission time. The automatic modulation mode selecting unit includes a mode select controller (202), a mode computer (204), and a mode select switch (206) for selecting a modulation mode based on a calculated optimized transmission time.
