OPLIN 4cast #423: Power to the (wireless) people
February 4th, 2015

revolution fistSo you have public Wi-Fi in your library, and your users 
are thankful. But how about power for recharging their wireless devices? 
Do they have to carry a cord and sit by the wall so they can plug in? 
Restaurants and coffee shops, the other popular places for public Wi-Fi, 
are increasingly providing wireless recharging stations at their tables, 
so users can simply lay their smartphones on a charging pad and load up 
on power. But nothing new is ever simple, and there are competing 
technologies for wireless charging at the moment. Recent news may make 
the choice of charging equipment a little easier for everyone.

  * Alliance for Wireless Power merges with Power Matters Alliance to
    push wireless charging standard
    <http://www.fiercewireless.com/story/alliance-wireless-power-merges-power-matters-alliance-push-wireless-chargin/2015-01-06>
    (FierceWireless | Mike Dano) "The A4WP was founded in 2012 to push
    the Rezence-branded technology for magnetic resonance wireless
    charging, and it counts Broadcom, Intel, Qualcomm, Samsung and
    others as members. The PMA was founded in 2012 to push its inductive
    charging technology, and its backers include AT&T, Duracell,
    Powermat Technologies and Starbucks, which has added PMA-capable
    chargers into some of its coffee stores. The groups said they would
    now jointly push wireless charging due to the merger, but that both
    technologies would continue to be available so that members could
    use whichever made the most sense."
  * Alliance for Wireless Power and Power Matters Alliance agree to
    merge <http://chipdesignmag.com/single.php?lnarticle=2282190283>
    (Chip Design | press release) "Consumers will gain access to an
    exciting and enhanced battery charging and power management
    experience sooner across the full spectrum of devices in daily use.
    Mobile network operators and commercial and retail brands can commit
    to the necessary investment confident of stable, long-term evolution
    and management of innovative wireless charging technologies."
  * Two rival groups pushing wireless charging declare peace
    <http://blogs.wsj.com/digits/2015/01/05/two-rival-groups-pushing-wireless-charging-declare-peace/>
    (Wall Street Journal Digits | Don Clark) "The two groups had already
    made signals that they were moving closer together. Meanwhile, the
    third group-called the Wireless Power Consortium-claims 200 members
    including Philips and Microsoft. It supports a standard called Qi
    (pronounced 'chee'), which it says combines elements of both
    inductive and resonance technology. Most Windows Phone handsets, and
    some Android smartphones are currently Qi compatible."
  * Key wireless charging groups A4WP, PMA agree to merge
    <http://www.cnet.com/news/key-wireless-charging-groups-a4wp-pma-agree-to-merge/>
    (CNET | Roger Cheng) "The two groups believe the merger will close
    by the middle of 2015, and plan to chose a new name for the combined
    group. The WPC, meanwhile, said the merger wouldn't have an effect
    on its efforts to bring wireless charging capabilities to the
    consumer. 'The two groups are filling gaps with technology the other
    didn't have, and they have been behind in rolling out commercial
    products,' said John Perzow, vice president of market development
    for the WPC."
