Does TI have any low-power wifi modules?

Hi, everyone

I am doing a project which needs low power wifi chip. Does or will Ti have this kind of chip?

I am trying to use CC3000 but seems it is not a low-power choice.

Regards

Zheng

    Hi Wu,

    Wifi low power techniques are achieved mostly by using algorithms that ensure efficiency. For a certain communication range and data rate, there will always be a certain amount of power that is physically required.

    Hi, Aaron

    Sorry that I forgot verifing your answer. I was busy in the project. Your r right. By making the chip into sleep mode, I think we can achieve low power target. And msp430 itself is also low power unit.

    I created a low power mode where a 400mAh battery last over 2 months even while cc3000 connects ~6times a day.
    Of course the msp430 sleep most of the time, when it wakes up and if transmission is pending is set the cc3000 with the Enable pin.

    tcp client mode is a must (calling out) and the server (that is always on) have a que of user data to send to it.
