Techniques are disclosed involving media access. For instance, wireless connections may be assigned into one or more groups. The assignments may be based on interference characteristics. Connection(s) within each of these groups may have acceptable interference characteristics with each other. Further, media access may be granted based on these groups. For example, if a device wishes to communicate across one of the connections, access may be granted for concurrent connections among all connections in the corresponding group. The granting of such access may be performed by a centralized controller device, such as an access point.
