IEEE 802.11 (Wi-Fi)

Atmel Wi-Fi offers ultra-low power single-chip Wi-Fi solutions which allow enable battery-powered peripherals—such as remote controls, cordless mouse/keyboard products, and headsets/speakers—to communicate directly with many Wi-Fi-enabled devices. The Atmel approach leverages a platform's existing Wi-Fi device to provide concurrent WLAN and WPAN functionality. This breakthrough convergence delivers unprecedented cost savings for systems developers and solves integration and coexistence problems associated with legacy WPAN approaches like Bluetooth and proprietary technologies.
