MediaTek (News - Alert), a provider of wireless communications and digital multimedia solutions, has unveiled a multimode inductive and resonance wireless charging solution at CES (News - Alert) 2014.
The wireless charging solution is the first such charging technology that uses in-band communications.
Inductive technology used in traditional wireless charging is tightly coupled. In its new wireless charging solution MediaTek has adopted loosely coupled technology commonly referred to as resonance, which delivers several advantages over the traditional inductive approach, MediaTek said.
For example, the resonance technology provides charging devices with the freedom of movement with easy, imprecise placement of the device. Users can charge multiple devices concurrently from a single affordable charger coil. They can charge different sized devices with different power needs using the same charger.
Additionally the resonance technology allows charging of different devices with vastly different form factors without the need for precise coil to coil alignment. It also allows charging devices across distances, through furniture or even walls.
With its resonant charging solution, MediaTek expects to deliver ease of use and convenience for users, says Mark Estabrook, director of Strategic Marketing at MediaTek.
“Most analysts agree that the adoption of wireless power is being slowed by competing specifications," said Estabrook. "MediaTek has developed leading technology that will overcome those specification differences even across such different technologies as induction and resonance."
MediaTek has also introduced a new multimode receiver wireless power solution that allows users to charge their devices from existing inductive chargers or new resonance chargers. It uses in-band communications for power control in both the inductive and resonant modes, delivering greater simplicity and higher value than proposed Bluetooth implementations for resonance.
Estabrook added that MediaTek’s technology will also ensure that capital investments made in chargers for the home, office, retail and automotive markets will be protected. "Users benefit from being able to charge on virtually any charger platform regardless of underlying technology employed."
Shipment of wireless charging receivers touched 20M in 2013, according a research from IHS (News - Alert). Majority of them were integrated into mobile phones and tablets. IHS forecasts this number to grow to 700M by 2018.
In another research study conducted earlier in October 2013, WinterGreen Research predicted that wireless phone charging market will touch $33.6 billion in considerations by 2019 thanks to the growth of smartphones. While wireless phone charging is considered a perquisite for a high end device, it is soon expected to become a necessary feature, the research said.
