Explicit congestion notification (ECN) bits that have traditionally been utilized in end to end congestion mitigation can be redefined to identify and compare congested and uncongested wireless accesses. Accordingly, mobile devices or other user equipment can leverage ECN data in order to make intelligent network selection, e.g., selecting a network with no congestion over one in a congested state. Accordingly, an application executing at the mobile device can send or receive data via the selected network that is selected based on ECN data.
