Many of the IoT and other applications that are battery operated demand low power modes. WiLink8 offers multiple features for enabling low power operation. Apart from the Wi-Fi Alliance standard defined WMM APSD, the device offers other features as well. Wake on Wireless (WoW) feature enables power saving for the attached host processor as well. The WiLink8 device can wakeup the host when it detects specific Wi-Fi activity thus enabling system level power saving. Also when the device is not actively transmitting data it can enter into a low power state and wakeup to listen to beacons. The learning algorithms implemented in WiLink8 enable the device to use this feature efficiently with any AP.
The device also supports a power management scheme in AP mode. AP Enhanced Low Power (ELP) mode can put the AP into sleep state when there is no active data transaction from the connected stations thus reducing the idle current consumption to 800 μA.
