The Part 15 power limit (one watt) applies to all unlicened devices in this band, and there's no higher limit for "professional" devices. That said, I've read that most WiFi equipment runs between 20mw and 200mw. So check your spec sheets if looking to upgrade a device. I suspect a device using the lower end of that power range does so not out of courtesy but to use cheaper parts.
Of course, Part 15 prohibits you from using a non-type-certified antenna too.
