Wireless charging not tasteless: new charge RADIUS up to 4.6 m-Wireless charging-IT information
Wireless charging is a quite a tangle of technology, a few years ago, it was supposed to be the next trend in consumer electronics, but still a niche technology. Compared to less reliable, requires accurate placement, slow charging, wireless charger, people still prefer the USB data cable and charger.
Of course, some manufacturers in an effort to change the predicament of wireless charging, such as Samsung, S6, S7, can support a variety of standards, at least you don't have to purchase a specific wireless charger. In addition, such as the Qi standard are high charging power 15W products became popular, solve the problem of charging speed. But then again, although concerns of wireless charging technology, but in popularity, also need to wait for the arrival of evolutionary time.
Wireless charging problem
Wireless charging is one of chaos with different standards, Qi, PMA, A3WP and other difficult to remember naming standards, are confused, you don't know and don't care about their mobile phone in which a camp, because it is not a necessity.
With the integration of industry, PMA and A4WP into a new AirFuel (Rezence standard), and Qi forms two strong potential. Samsung S6 models such as the previously mentioned support all wireless-charging standard, seemed to make the mess a little better. However, Qualcomm and participate, introduced the WiPower, however it is based on the Rezence, is a metal barrier to Wireless charging, power and other improvements.
However, the fact is that manufacturers are still clamoring for standards, performance, but they are still not cold, because at bottom using a coil or resonance forms of wireless charging, short distances, harsh positioned still exist shortcomings, the most important thing is they are not standard wireless Chargers, who would be willing to spend more money to buy?
Family and public development
It seems so that most people pay extra to buy a wireless charger is not realistic, but some good concept has emerged, and became interested in people.
First, of course, is the Wireless charging home from IKEA products. A table lamp, a bedside table, integrated wireless charging area, users can put the phone in charge before going to bed, it is human, it is consistent with experience in people's imagination. However, charging lack of Qi-enabled phones such as iPhone, still need to use the phone, which is an obstacle to the use of, IKEA is Qi's old standards, only 5 w, essentially not change the Wireless charging the chicken situation.
Another good sign is that some countries and PMA area Starbucks cafes design standard for Wireless charging platform, allows users to more easily charged at the coffee shop, but also an effective marketing strategy to attract customers; Netherlands and the United Kingdom in places such as McDonald's and Ibis hotels, Qi was designed charging station, for people to use free of charge. If more and more business environment equipped with Wireless charging station will affect mobile phone manufacturers more actively into the feature, but this process is quite difficult.
New technology will revolutionise wireless experience
About wireless charging, the new technology is also in active development, and the industry is somewhat more optimistic signal charging technology. In simple terms, RF signal transmitting station in one locale, then a range of compatible device can automatically receive signals and act as compared with coil inductive technology closer to the real "Wireless charging". At present, including Energous, the company's products, can provide the radius of approximately 4.6 metres distance, while the ultimate goal is further away .
Of course, it always takes a long process of testing of new technologies, improving business, Wireless charging is still not a necessity, but new technology has made it full of the future, we need to do is focus and waited.
无线充电不再鸡肋：新技术充电半径将达到4.6米 - 无线充电 - IT资讯
无线充电是一项颇令人纠结的技术，在几年前它曾被认为是消费电子领域的下一个趋势，但至今仍是小众技术。相比不够可靠、需要精准摆放位置、充电速度慢的无线充电器，人们还是更喜欢USB数据线和充电器。
当然，一些厂商在努力改变无线充电的窘境，比如三星S6、S7，可以支持多种标准，至少你不用再去购买特定的无线充电器。另外，诸如Qi等标准也在加大充电功率，15W的产品也开始普及，解决充电速度的问题。不过话说回来，虽然无线充电技术值得关注，但要想普及，还需要等待进化时刻的到来。
无线充电的大问题
无线充电乱象之一便是不同标准，Qi、PMA、A3WP等一系列难记命名标准，令人一头雾水，你不知道、也不关心自己的手机身处哪一个阵营，因为它并非是必需品。
随着产业的整合，PMA和A4WP合并成为新的AirFuel（Rezence标准），与Qi形成两强之势。而前面提到三星S6等机型支持所有无线充电标准，似乎让此前的混乱变得好了一些。不过，高通又参与进来，推出了WiPower，不过它基于Rezence，只是对无线充电的金属阻隔性、功率等进行改进。
然而，事实上情况是厂商们仍在叫嚣着标准、性能，但用户们仍不感冒，因为本质上使用线圈或是共振形式的无线充电，仍存在传输距离短、摆放位置严苛等缺点，最重要的是厂商们并非标配无线充电器，谁愿意去多花钱购买呢？
家庭化及公共化发展
似乎，让大部分人花钱额外购买无线充电器并不现实，但一些好的概念已经出现，让人们产生了兴趣。
首先，自然是宜家的无线充电家居产品。一款台灯、一个床头柜，集成无线充电区域，用户们可以在睡前把手机放在上面充电，这很人性化，很符合人们想象中的使用体验。不过，iPhone等缺乏Qi充电功能的手机，依然需要使用手机壳，这是使用上的一个障碍，另外宜家采用的是Qi的老式标准，仅提供5W功率，本质上没有改变无线充电的鸡肋处境。
另一个好的现象是某些国家及地区的星巴克咖啡厅设计了PMA标准的无线充电台面，让用户可以在咖啡厅更方便地充电，也是一种有效吸引顾客的营销策略；荷兰、英国等地的麦当劳和宜必思酒店，则设计了Qi充电站，供人们免费使用。如果越来越多的商业环境开始配备无线充电站，会影响手机厂商更积极地置入该功能，但这个过程还是比较艰难的。
新技术将彻底改变无线充电体验
关于无线充电，新的技术也在积极开发中，目前业内比较看好的是射频信号充电技术。简单来说，在一个区域设置射频信号发送站，那么一定范围内的兼容设备便可自动接收信号并充当，相比线圈感应式技术更接近真正的“无线充电”。目前，包括Energous等公司的产品，已经可以提供半径约4.6米的发射距离，而最终目标则更远。
当然，新技术总是需要漫长的过程测试、完善直至商用，无线充电目前仍不是一种必需品，但新技术让它充满未来，我们需要做的便是关注并且等待。
