Saving Energy with Your Thomson Gateway
Code of Conduct v3
To prove its commitment to protect the environment, THOMSON has signed the Code of Conduct v3
(CoC v3), an agreement to reduce the power consumption of broadband devices.
It provides rules for the power consumption in:
±
Full power state:
This is the normal operation mode of the device, where all functionality is enabled.
±
Low power state:
When there is no user traffic on the device, the device should switch to low power mode. This is a state in
which devices are only allowed to use a limited amount of energy to be able to power its components
and respond to user activity.
Example:
Take the following example:
±
The user switches off his computer at 20:00.
±
There are no other devices connected to the Thomson Gateway.
The Thomson Gateway switches to low power mode. This results in a considerable drop in the overall power
consumption of the Thomson Gateway.
THOMSON power saving innovations
On top of the CoC v3 measures, THOMSON has developed the
Automatic Power Management
to further
reduce the power consumption.
Automatic Power Management
The Thomson Gateway constantly monitors the user activity and uses this information to optimise the power
consumption:
For example:
±
When there is no or low user activity, the Thomson Gateway
reduces the clock frequency of the central
processor
. The lowered clock frequency will result in a lower power consumption.
±
Switch the wireless interface to a reduced power mode
in which the access point is available for
connection, but other functions are turned off. This is only possible if there are no devices connected to
the Thomson Gateway.
