A first edge device mounted on a vehicle includes a processor that communicates sensing information in a real time or near real time to a central cloud server, where sensing information includes position information of the first edge device and a time-of-day. Based on the time-of-day and a specific initial access information obtained from the central cloud server, the processors sets the following: a first beam index at the first edge device for an uplink communication and a second beam index at the first edge device for a downlink communication, a specific physical cell identity which indicates a first base station to which the first edge device is to be connected, a first wireless carrier network (WCN) from amongst a plurality of different WCNs at the edge device, and a beam configuration to service one or more user equipment in a surrounding area of the first edge device.
