A device can have collocated communication circuits and operate in a parallel mode if selected first wireless channels are above a certain quality, and operate in a time division (TD) mode if the selected first wireless channels are below a certain quality. The parallel mode can include using first channels for a first protocol that do not overlap a second channel used by a second protocol. The TD mode can include first time periods in which a first protocol uses first channels that overlap the second channel, while the second protocol is inactive, and second time periods, in which the first protocol is inactive and the second protocol is active.
