摘要

The present invention relates to a communication unit (3) in an at least partially remotely controlled mining machine (5). The invention also comprises an at least partially remotely controlled mining machine (5) comprising such a communication unit and a method for remote control of an at least partially remotely controlled mining machine. Said communication unit (3) in an at least partly controlled mining machine is adapted for transferring remote control information between a machine operator and a control system in the mining machine via one or more access points in a wireless communication system in a mine. The communication unit (3) further comprises a radio unit and two or more antennas provided in a space defined by an enclosing protective housing. Said two or more antennas are directional antennas. The radio unit is adapted for data communication with the control system of the machine via one or more data links.
