Dynamic switching of power levels in device having different wireless communication circuits

A device, comprising:

• first communication circuits configured to
• in a first mode of operation, receive data units over first channels without encoding for forward error correction (FEC) at a receiving device, and
• in a second mode of operation, receive data units over the first channels with encoding for FEC at a receiving device;
• and
• second communication circuits coupled to the first communication circuits, and configured to
• transmit data units across a second channel at a first power level if the first communication circuits are operating in the second mode of operation, and
• transmit data units across the second channel at a second power level, lower than the first power level, if the first communication circuits are operating in the first mode of operation.

A system, comprising:

• a combination device that includes
• first communication circuits configured to
• establish a wireless communication link with first type devices according to a first mode or a second mode,
• the first mode including receiving data units over a set of first channels without encoding for forward error correction (FEC), and
• the second mode including receiving data units over the first channels with encoding for FEC, and
• second communication circuits configured to
• establish a wireless communication link with second type devices over at least a second channel that overlaps a plurality of first channels,
• transmit data units over the second channel at a first power level if the first communication circuits are operating in the second mode, and
• transmit data units over the second channel at a second power level lower than the first power level if the first communication circuits are operating in the first mode.
