The A4WP uses resonant charging technology, called Rezence™, that allows consumers to "drop and go," placing multiple devices on a single charging surface without the trouble of accurate positioning or alignment. Broadcom's multi-standard smartphone power management unit drives Rezence™ technology into the mainstream while providing compatibility with existing deployments. When combined with Broadcom's WICED™ (Wireless Internet Connectivity for Embedded Devices) Smart family of SoCs and software for the charging pad, manufacturers can now build complete end-to-end wireless charging packages.
