For instance, a computing device may include multiple chipsets with associated antennas that are configured to perform wireless communications using separate wireless standards which operate at overlapping frequencies. To avoid performance degradation experienced in simultaneous use cases with communications operating at overlapping frequencies, the multiple chipsets may be configured with logic to determine which communications are prioritized when multiple chipsets attempt to communicate simultaneously. The multiple chipsets may be communicatively coupled to coordinate their communications by prioritizing certain types of communications over other types of communications to avoid simultaneous communications in overlapping frequencies.
