The technology described herein is directed towards a transcoder device (node) that leverages multipath routing techniques using both terrestrial and satellite links simultaneously. The transcoder device implements the multipath transmission control protocol (MPTCP) along with metasurfaces, such as to support satellite, ethernet, Wi-Fi, and new radio (e.g., 5G) interfaces. The transcoder can decode and reencode data packets at the packet level to facilitate communication between user equipment (UEs) and existing Satcom satellites. A metasurface redirects signals from the satellite to a satellite radio frequency (RF) interface of the transcoder, with the transcoder also coupled by a UE RF interface to a UE, such as a computing device or cellphone. For direct-to-device communications, transcoder conversion is bypassed. Various additional functions facilitate such satellite service, including via frequency conversion, doppler manipulation, a repeater, and frequency equalization / negative-slope compensation.
