Coaxial cable interface to outdoor broadband unit
An outdoor broadband unit implements full IP-based routing between a wide area network (WAN)-side interface (such as a Long-Term Evolution (LTE) air interface) and a local area network (LAN)-side interface (such as a home network using MoCA protocol). The outdoor broadband unit maintains a routing table for all connections through an internal routing system based on matching between WAN-side Internet Protocol (IP) addresses and/or ports and LAN-side IP addresses and/or ports. The outdoor broadband unit may support both connection-oriented transport layer routing (such as Transmission Control Protocol (TCP)) and connectionless transport layer routing (such as User Datagram Protocol (UDP)).
