This object reports, as a text string, the current operating mode configured on the Cisco URWB wireless device. An admin managing a mesh of these radios can check this field to confirm a unit is running in the intended mode, since URWB devices can typically be configured for different roles such as trackside infrastructure versus mobile onboard use. If a device meant to act as a fixed trackside radio unexpectedly reports a mobile-oriented operating mode, the admin would recognize a misconfiguration that could disrupt the mesh topology.
