1. A communication configuration system for a fleet of autonomous vehicles (AVs) in a given region, the communication configuration system comprising: one or more processors; and one or more memory resources storing instructions that, when executed by the one or more processors, cause the communication configuration system to: receive localization data from a respective AV of the fleet of AVs, the localization data comprising a location and an orientation of the respective AV; using a network resource map, select a proximate network node relative to the respective AV based on the location of the respective AV, the network resource map indicating locations of network nodes for connecting the fleet of AVs with a backend system; and based on the orientation of the respective AV, transmit configuration commands to the respective AV to cause the respective AV to configure an on-board communication system to transmit and receive data with the proximate network node.
