IOT EDGE DEVICES UTILIZING MULTI-TRANSPORT MEDIUMS (BLUETOOTH MESH, WIFI MESH, CELLULAR) TO CONTROL DELAY AND JITTER

An apparatus comprising at least one integrated circuit configured to cause the apparatus to: determine delay information and/or jitter information for a first plurality of data units in a first data transmission, the first plurality of data units in the first transmission being received by a receiving device via a plurality of different connections from a transmitting device; in dependence on the determined delay information and/or jitter information for the first plurality of data units, determine for a second transmission of a second plurality of data units, which one or more of the second plurality of data units is to provide redundant data, the second transmission to be received by the receiving device via the plurality of different connections between the transmitting device and the receiving device, the second transmission being subsequent to the first transmission; and cause information about which one or more of the second plurality of data units is to provide redundant data, to be provided to the transmitter.
