The mobile chipset manufacturer, Qualcomm, has just
announced its readiness to compete in the wireless charging segment. This
company develops a similar innovation but with a different concept and standard
with the wireless chargers that have existed in the market.
Called WiPower, this technology doesn't use the standard Qi
and PMA that have been used by a number of vendors. It relies on a new wireless
charging standard called Rezence. Qualcomm wants this technology can be
embedded in devices made of metal.
The standard of Rezence wireless charging is developed by
the Alliance for Wireless Power (A4WP) and has been demonstrated in January.
WiPower works at the frequency that's more tolerant to
objects that are made of metal. It allows metal devices including smartphone to
be charged wirelessly without requiring physical contact.
WiPower uses basic technology of Near Field Magnetic
Resonance that's more flexible and appropriate to be applied to this wireless
charging method. Other advantages, this standard technology can charge multiple
devices at once in the same time.
Wireless charging is actually not a new technology, but it
hasn't commonly been used by devices on the market. The reason is because the
method used by software vendors requires the additional chargers to have the
same standard, if not then this technology can’t be used at all.
The development of WiPower by Qualcomm becomes a new hope to
eliminate this limitation, allowing device manufacturers to give wireless
charging support to more variants.
