A modular wireless communications system (edge device, etc.) that includes a base unit having a base unit processor and one or more additional units that each include a processor, in which the base unit processor is configured with processor-executable software instructions to determine whether the base unit has been combined with the one or more additional units to create a combined unit and/or whether one or more of the additional units have been detached from the combined unit. The processor may automatically perform an edge reconfiguration interrogation and enumeration (ERIE) operation in response to determining that the base unit has been combined with the one or more additional units to create the combined unit or in response to determining that one or more of the additional units have been detached from the combined unit.
