The Wireless Communication Unit (WCU) is the in-vehicle unit running the WICE WCU software and communicating with the vehicle and the WICE back-end.

WCU:s are identified by a unique text string, which by convention is the MAC address of (one of) the ethernet interfaces in the unit. The WCU id is configured on each WCU (automatically from the MAC address) and is a search parameter available in the WICE Portal web-GUI.

The WCU software is delivered as a self-extracting application installation package, which can be run on the WCU:s manually from a command prompt, using a suitably prepared USB stick, or updated remotely using the WICE Portal mechanism for remote software upgrades (see below).

The WCU hardware platform supports a number of communication interfaces, such as CAN, LIN, FlexRay and Ethernet and can be configured in different ways using the WICE Portal. The WCU platform can also support some limited user-interaction through light-emitting diodes (LED) on the side of the unit. A description of the LEDs is available here.
