Rezence (pronounced reh-zense) is an interface standard developed by the Alliance for Wireless Power (A4WP) for wireless electrical power transfer based on the principles of magnetic resonance. The Rezence system consists of a single power transmitter unit (PTU) and one or more power receiver units (PRUs). The interface standard supports power transfer up to 50 watts, at distances up to 5 centimeters.〔(【引用サイトリンク】url=https://www.youtube.com/watch?v=oseV55j1g3w )〕 The power transmission frequency is 6.78 MHz, and up to eight devices can be powered from a single PTU depending on transmitter and receiver geometry and power levels. A Bluetooth Smart link is defined in the A4WP system intended for control of power levels, identification of valid loads and protection of non-compliant devices.〔(【引用サイトリンク】url=http://www.rezence.com/technology/technical-specification )〕〔(【引用サイトリンク】url=http://www.wirelessoutlook.com/technology/bluetooth-based-wireless-charging-rezence-a4wp/ )〕 The A4WP was formed in early 2012 with the intent to create a wireless power transfer standard to compete with the existing Qi standard.
