Challenges of Mobile Computing

Mobile computing presents the following challenges.


Mobile platforms spend much of their time attached to AC power. At those times they are like other desktops. Intel AMT can operate even when the platform is powered down, and it can be configured to operate in a low power state until it is awakened due to an external stimulus from the network.

When a mobile platform is operating on batteries (DC power) or even when the platform is asleep on battery power, it is essential to minimize DC power use, which means setting limits to Intel AMT activity on DC power.

Multiple Network Connections

A mobile platform, when docked, may have a wired LAN connection. It may also have a wireless LAN connection. Both of these connections can be active simultaneously or only one of them may be active. Manageability network traffic can be present on both of the network connections simultaneously.  Beginning from Release 9.5, some platforms have no wired interface.

Security in a Wireless Environment

Wireless traffic requires additional protection beyond that used on a standard wired LAN. Unauthorized platforms may attempt access to a wireless network, and wireless traffic is subject to interception by unauthorized platforms. To eliminate these problems:

   A wireless network access point must verify the identity of a device attempting to connect to it and validate that the device is authorized to connect to the network.

   The traffic must be protected from prying by unauthorized targets that can pick up the wireless transmission.

Intel AMT must be able to exchange manageability messages with a remote management console over a protected wireless LAN.

Working Inside and Outside the Enterprise

When a mobile platform is outside of the enterprise network and is connected to a foreign network (for example, at home, in an airport or hotel, or at a customer site), it cannot be managed by a management console inside the enterprise network. Intel AMT can be configured to reject manageability traffic outside of the enterprise network, in order to prevent unauthorized management consoles from attempting to access the device. Intel AMT must be able to detect if the platform is inside or outside the enterprise network. Tunneled manageability messages may still reach the platform, if the platform is configured to receive them.
