Official Rezence brandmark, the A4WP uses this mark of interoperability to show that various devices are compatible with Rezence systems.
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,[1] at distances up to 5 centimeters.[2] 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 Low Energy link is defined in the A4WP system intended for control of power levels, identification of valid loads and protection of non-compliant devices.[3][4]
The A4WP was formed in early 2012 with the intent to create a wireless power transfer standard to compete with the existing Qi standard. Board member companies[5] include Broadcom, Gill Electronics, Integrated Device Technology (IDT),[6] Intel,[7][8] Qualcomm, Samsung Electronics,[9] Samsung Electro-Mechanics, and WiTricity.[10]
