1. A method comprising:
- increasing the power level of a wireless transmission by using power control that is capable of being open loop or capable of being closed loop, wherein said open loop power control enables a transmitter to unilaterally modify the power based on packet errors if a number of packet errors in a short observation window exceeds a first threshold; and
decreasing, by using power control that is capable of being open loop or capable of being closed loop, the power level of the wireless transmission if a number of packet errors in a long observation window falls below a second threshold.

Abstract
Power is controlled by increasing the power level of a wireless transmission if a number of packet errors in a short observation window exceeds a first threshold. Power is controlled by decreasing the power level of the wireless transmission if a number of packet errors in a long observation window falls below a second threshold. In various embodiments, power is controlled based on packet error rate using both open and closed loop feedback to manage power at an increased level of granularity.
