A mobile broadband (MBB) device provides a mobile computer with a wireless data connection to a cellular service. An MBB device supports one or more cellular radio technologies, such as GSM, 3G, CDMA, or LTE. MBB devices in modern standby platforms are all required to provide the same set of power management capabilities and to implement the same general hardware configuration, regardless of the specific cellular technologies supported.

The MBB device is expected to use Universal Serial Bus (USB) to connect to the modern standby platform, and to use software provided by Microsoft for all connectivity and power management operations. Windows includes an inbox Mobile Broadband Class Driver, which provides a standardized interface for mobile broadband data transfer, connection management, and power management for MBB radios. The following guidance focuses on power management for MBB devices that are integrated inside the mobile computer chassis. MBB devices that connect to an external USB port are not discussed.

During modern standby (when the screen is off), the MBB device is expected to be in a low-power state. How much power the MBB device consumes in this low-power state depends on whether the user has provisioned the MBB device on the cellular network. If the MBB device is provisioned and the radio in the device is currently enabled by the user for a data connection, the device should be in a low-power connected-sleep mode in which the device's USB function is in the D2 (suspend) device power state. However, if the MBB device has not been provisioned on the network or the user has disabled the radio for a data connection, the device should be in a low-power radio-off mode. In radio-off mode, the MBB device has only enough power applied to respond to host commands over the USB interface.

The implementation of MBB device power management for a modern standby platform is based on the following:

The user-controlled radio power state of the MBB device.
The USB bus suspend and resume transitions.

The MBB device must be able to enter a low-power D2 (suspend) state after the MBB radio is turned off and the USB bus interface enters the suspend state. All sleep and wake power transitions must be signaled over the USB bus. There is no support for out-of-band GPIO signaling to initiate MBB device power transitions or to interrupt the main processor on the System on a Chip (SoC) or core silicon.

If the radio in the MBB device is currently enabled by the user for a data connection, the device must be able to use in-band, USB resume signaling to wake the SoC or core silicon from modern standby. The SoC or core silicon must be able to wake from its lowest power state in response to in-band, USB resume signaling from the MBB device.

Power management modes

The MBB device is expected to support five power-management modes.These modes are a combination of provisioned, connectivity, and radio power states. A transition from one mode to another is communicated to the device directly over the USB bus through commands from the Mobile Broadband Class Driver or USB device state transitions. Transitions between power management modes must not use external GPIO signaling.

The five power-management modes are:

Active

The radio is actively transmitting data or is actively connected to the cellular network.

Connected-sleep

The radio is provisioned on the network and a user account is enabled. The platform is in modern standby. The MBB device is waiting for data from the network to wake up the SoC, and also for events from the SoC. Average across 2G, 3G, LTE, and various DRX modes.

Radio-off

The radio is provisioned on the network, but Windows or the user has turned off the radio in the MBB device.

No-subscription

The user does not have an active subscription.

No-SIM

The device has no SIM.

The following table compares the five power-management modes.

Power management mode	Radio power state	USB device power state (Dx)	Average power consumption	Exit latency to active
Active	On	D0	Scenario-specific	N/A
Connected-sleep	On	D2 (selective suspend)	<= 15 milliwatts (device-specific)	USB D2 -> D0 <= 400 milliseconds (USB specification)
Radio-off	Off	D2 (selective suspend)	<= 5 milliwatts	USB D2 -> D0 < 400 milliseconds + Base station acquisition and registration (specific to location and carrier)
No-subscription	Off	D2 or D3	<= 3 milliwatts	N/A
Metrologic port devices drivers. No-SIM	Off	D2 or D3	<= 3 milliwatts	N/A

Note In no-subscription mode and no-SIM mode, an MBB device can be in either the D2 or D3 device power state, depending on whether the device supports D3.

The power consumption of the MBB device in each of the power modes shown in the preceding table will vary by radio implementation, network type, and distance from the cellular access point. Contact the radio manufacturer for information about the device-specific power consumption in each power management mode shown in the preceding table.

Software power management mechanisms

The two primary software power management mechanisms for the MBB device are the radio power state and the USB function power state.

Radio power state

The Windows Mobile Broadband Class driver will send a MBIM_CID_RADIO_STATE message to the MBB device with a command to turn the radio power state to on or off per the user's preference. Ines test and measurement driver download. When the user disables the radio, the Mobile Broadband Class driver will send the MBIM_CID_RADIO_STATE message with an MBIMRadioOff command.

USB selective suspend

The Windows Mobile Broadband Class Driver is a Windows Network Driver Interface Specification (NDIS) miniport driver. The Mobile Broadband Class Driver and NDIS collaborate to manage the power of the MBB device. Windows will transition the USB function of the MBB device to the USB suspend (or, in Windows terminology, selective suspend) state when the MBB device should be in a low-power mode. The transition to the USB suspend state is independent of the radio power state.

Windows will transition the MBB device to connected-sleep mode (USB suspend (D2) state) when the system enters modern standby and the device is provisioned on the network. During connected-sleep mode, the radio is on, and the MBB device is expected to generate USB resume wake signaling and return to the D0 state when the radio receives new data from the network that matches programmed wake patterns or when other enabled wake events occur. The power consumption in connected-sleep mode will vary by cellular technology and distance from the cellular access point.

Windows will transition the radio to radio-off mode (USB suspend (D2) state) when the system enters modern standby and the device is provisioned on the network, but the user has set the radio power state to off. In radio-off mode, the MBB device is expected to consume no more than five mil
