Aspects of a system for physical layer aggregation may include one or more switch ICs and/or physical (PHY) layer ICs that enable reception of data packets via a medium access control (MAC) layer protocol entity. Each of the received data packets may be fragmented into a plurality of fragment payloads. Each of the plurality of fragment payloads may be sent to a PHY layer protocol entity instance a physical layer protocol entity instance selected from a plurality of physical layer protocol entity instances.
