This creatable/settable object configures the maximum uplink bit rate the device requests as part of a profile's UMTS QoS parameters. An admin sets this to cap or request the desired ceiling on upload speed for a given profile's data session, useful for shaping cellular usage for a specific application. For example, an admin provisioning a profile for a low-bandwidth telemetry device might request a low maximum uplink bit rate to keep usage predictable, even though the modem could physically support more.
