Quality improvement of au Wi-Fi (software update etc.)

The improvement of Wi-Fi quality has been performed on the latest models (released after May, 2012). The improvement has also been performed on released au smartphones with software updates, allowing users to use their phones more comfortably.
KDDI will continue to make every effort to offer higher-quality au mobile phone services and appreciate your understanding.

  1. Details of Wi-Fi quality improvement

    KDDI makes the following three improvements on customers' au smartphones, enabling them to use Wi-Fi more comfortably.

    • Countermeasure (1): Improvement of the battery length while Wi-Fi is on

      • To enable users to always have Wi-Fi on, power consumption performance when connected to Wi-Fi access points has been optimized.
        Accordingly, the battery length of the "standby time" is improved when using a smartphone with Wi-Fi turned on; it is nearly equivalent to the battery length of the standby time when using 3G communications only.

        * Varies depending on models and environments.

    • Countermeasure (2): Shortening of the waiting time for switching from 3G communications to Wi-Fi communications

      • Switching process from 3G communications to Wi-Fi communications has been optimized to shorten the time for completing the process.
        This reduces the waiting time to approximately half.

        * Varies depending on models and environments.

    • Countermeasure (3): Shortening of the waiting time for switching from Wi-Fi communications to 3G communications

      • Switching process from Wi-Fi communications to 3G communications has been optimized to shorten the time for completing the process.
        This reduces the waiting time to approximately half.

        * Varies depending on models and environments.
