Human-readable, semi-persistent overlay that dynamically displays a changeable operational state of a radio base station

摘要

A radio base station (10) for performing radio communication functions includes a human-readable, semi-persistent overlay (31) fixed to a surface of the radio base station. A nonvolatile memory (32) stores a current operational state of the radio base station. The human-readable, semi-persistent overlay indicates (40) at least with text characters or symbols on the current state (34). If the current state of the radio base station changes, then the text characters or symbols on the human-readable, semi-persistent overlay are updated to reflect the changed state. The indication of the changed radio base station state on the human-readable, semi-persistent overlay remains human-readable even if the radio base station is powered-down.
