FIELD: physics, communications.
SUBSTANCE: invention relates to wireless communication networks and is intended to detect the physical change of the exterior of a network node module which is part of a network node. According to the invention the network node module (19) comprises a movement detector (20) configured to detect movement between a male element and a corresponding female element, where the network node module comprises one of the elements and both elements are required for obtaining an operative network node, and a control unit (24) configured to generate an indication of a physical change of the network node module based on the detected movement.
EFFECT: detecting physical change of the exterior of a network node module which is part of a network node.
