This creatable/settable object configures the minimum acceptable guaranteed-uplink-bit-rate value for a profile's QoS negotiation. An admin sets this to establish a hard floor on the guaranteed (not just best-effort) uplink rate the profile will accept, important for applications needing assured minimum throughput. For example, a profile for a device that must reliably push periodic status updates might set this floor to ensure the guaranteed rate never drops low enough to delay those updates unacceptably.
