Smart wireless charging stations are generating a lot of interest right now, with OEMs and developers trying to create devices that have optimal power-control features. Recently, the Bluetooth Special Interest Group (SIG) and the Alliance for Wireless Power (A4WP) signed a memorandum of understanding (MoU) that establishes a formal liaison relationship within the consumer-electronics category.
After signing, the Bluetooth SIG issued a Universally Unique Identifier (UUID) to the A4WP for adoption in its baseline system specification (BSS). Bluetooth Smart, which uses magnetic-resonance-based wireless-power-transfer technology, can then be utilized as a radio standard. It will carry the session management and power control between an A4WP charging station and paired device.
Because of this integration, consumers will see devices initiating a charge more quickly when coming into contact with a charging surface. They also will enjoy improved power-control features, such as giving priority charges to one device when multiple devices are present. OEMs and developers also will benefit from the ability to create a new class of applications to leverage these charging stations, such as mobile payment and location-based services.
For the A4WP, Bluetooth Smart is expected to enable the delivery of a next-generation experience to consumers. Plans include not only one charging station for simultaneous devices, but freedom of placement on tabletops, desktops, and automotive environments. Bluetooth Smart also will aid the development of charging solutions that scale easily from devices ranging from wireless headsets to laptops.
