Dynamic switching of power levels in device having different wireless communication circuits
A method can include an integrated circuit device, determining if first communication circuits are operating in a first mode that wirelessly receives data at a first rate or a second mode that wirelessly receives data at a second rate that is lower than the first rate. If the first communication circuits are operating in the second mode, transmitting signals with the second communication circuits at a first power level, and if operating in the first mode, transmitting signals with the second communication circuits at a second power level that is lower than the first power level. In the first mode, X symbols per data bit are received and in the second mode, Y symbols per data bit are received, where X<Y. Corresponding devices and methods are also disclosed.
