US 11,706,129 B2 · Platform for redundant wireless communications optimization

Abstract

A communication system facilities low-latency, high-availability multipath streaming between terminals (e.g., mobile terminals) and a server platform. In an example application, a remote support service operating on the server platform provides remote teleoperation, monitoring, or data processing services to a mobile terminal embodied as a vehicle or robot utilizing a low latency communication link. The low latency link enables a remote operator to receive video or telemetry feeds, and timely monitor and respond to hazards in substantially real-time. The low latency communication link may be achieved even when the data streams are transmitted over public networks incorporating at least one wireless leg, and where individual connections have varying quality of service in terms of delivery latency due to congestion or stochastic packet losses. Assignment of data streams to particular communication channels may be made on an optimization model derived from a machine-learning process or simulation.
