A wide area mirroring router enables mobile device screen mirroring across a wide area network. The wide area mirroring router (WAMR) is in wireless communication with a mobile device to receive Internet Protocol (IP) packets, including multicast packets, containing data related to mirroring content displayed on the mobile device to a remote display device. The WAMR encapsulates the IP packets into envelopes for transmission via a tunnel to the remote display device over the wide area network.
