Abstract: A communication system may include a robotic garden tool and an external device. The robotic garden tool may be configured to receive a first location signal from a satellite, and to transmit calibration information regarding the first location signal to the external device. The robotic garden tool may be configured to remain stationary to act as a first base station with respect to the external device that is moved in an operating area during creation of a virtual boundary by the external device. The external device may be configured to determine, based on (i) the first location signal that is also received by the external device from the satellite and (ii) the calibration information from the robotic garden tool, a plurality of locations of the external device to be used as waypoints to generate the virtual boundary as the external device is moved within the operating area.
