Patent ID: 11277807

Abstract:
The present disclosure relates to delivery of data traffic over a wireless connection. In more particular, it relates to methods, a tunneling unit (208), and system for emulating wired connectivity between two or more robot devices (202, 204) and a controller (222). Buffering (212) of data frames, from two or more robot devices, received up-streams a wireless access network (206) is performed. Based on the time-stamps extracted (210) from data frames a relative time offset is determined for the two or more robot devices. Buffered uplink frames are forwarded (216) to the controller in a pre-define order, enabling using the relative time offset when forwarding downlink frames (232), being received over the wireless access network (206), to said two or more robot devices, such the that the downlink frames reach each one of two or more robot devices simultaneously. A deterministic delivery of data frames over a wireless connection is provided.
