I'm pretty sure that high speed is just 802.11e frame aggregation or similar. > For high power I don't think this is the case.

But that doesn't necessarily mean that it needs to be programmed differently. The eeprom settings and the calibration is quite flexible so a higher power chip with the appropriate feedback would be sufficient. johannes
