There is light on the Internet What is known as Li Fi than Wi Fi cattle

　　Even if you've never heard of Li-Fi, you can now know what it is. Li-Fi (Light Fidelity) is a new Wi-Fi technology, it is realized mainly through the visible spectrum for wireless data transmission. This exciting technology first appeared in in a speech Professor Harold Hass of 2011.

　　This year Spain MWC Mobile World Congress in Barcelona, PureLi-Fi company gives us Li-Fi of the actual product, so what it have to do with Wi-Fi different? to find out.

　　PureLi-Fi network chief operating officer at Harald Burchardt when in an interview said: "Li-Fi works is very simple, we communications wireless signal by LED lamps, it is somewhat similar to Wi-Fi, however we are using LED lamps and other lighting medium to complete the wireless data communications. "

　　It is understood that Professor Harold Hass from 2003 began to study this Li-Fi technique, as he foresaw the looming spectrum crisis. At about the same time, new LED lighting technology begin to hit the market, and Professor Harold Hass came up with idea of bringing them together. Eventually, he found a way to use these electronic lighting set up to achieve high-speed data transmission method, and without disrupting the existing infrastructure of radio frequencies.

　　PureLi-Fi founded in 2012 the company's main objective is to commercialize the technology of Li-Fi. And they show the actual product is a u-shaped adapter, top is equipped to receive light signals light and infrared camera receiver. In addition, stand above or compatible Li-Fi settings for wireless data transmission LED lights and the transmitter.

　　According to Digital Trends reports, this product at the MWC Conference data transfer speeds of up to 40Mbps, and in the case of light reflection to achieve strong stability, light edges will decline, thanks to the reflective light equipment there is no problem with the connection, walking does not affect use.

　　Harald Burchardt noted that has two key advantages of the Li-Fi technology, which can transmit more data within a local area, and security is higher. He explained: "in the Li-Fi environment, the total capacity of the data will be promoted, coupled with the light cannot pass through the wall, therefore, compared to Wi-Fi, we create networks will have a higher degree of security. "

　　In addition, Harald Burchardt said: "as the technology matures, ideally we want this product is reduced in size, will make it a integrated circuit module, and then used in smartphones, tablets, laptops, wearable devices and other types of electronic devices. " Ted Baker iPhone 6 covers

　　However, Harald Burchardt finally admits that the technology is promising, then it also needs 10-15 to appear in each LED lights or on every piece of electronic equipment, and PureLi-Fi the company you want to do is in a relatively short period of time to achieve this goal.

Deserved the strongest Win 10 Mobile HP Elite X3 hands on review

　　HP Elite X3 can say is one of the biggest attractions on the MWC Conference this year, powerful performance, it was named the "most powerful Windows 10 mobile" name.

　　Let us take a look at Elite X3 can do: it has 2K 5.96 inches screen resolution, 2.15GHz Gao Tongxiao 820 processor and 4GB, DDR4 RAM. The allocation alone is quite powerful and Elite X3 has three working modes, in addition to mobile phones, Continuum, but also through a Mobile Extender accessories truly transforms into a laptop!

　　HP Elite X3 what is a device? It can save the mobile version of Windows for 10? With problems we started testing it:

　　Design

　　As a separate mobile phone, Elite X3 gives the impression was good, but it is 5.96 inches screen is too big, you sometimes use it as a cell phone, especially if you realize that it is still better than Nexus 6, Galaxy Note 5 more times. You can't master it with one hand.

　　However, although the Elite X3 really feels great in the hand, but its design is very simple, narrow border makes big screen looks more fun. On the phone side you can see the thin silver parts, it's slightly longer at the bottom to accommodate B&O stereo speakers.

　　Funny thing is, speaker grille is not the kind of uniform layout, but imitates the style of the graphic equalizer, very smart. It's hard to imagine they would see this design on a business machine, it also makes the Elite X3 compared to those who look to be serious competitors for more lively.

　　Although Elite X3 front and side edges are wrapped in metal, but it's the back shell is polycarbonate. Combined with smooth glass front, is always there when you take it you can not hold the illusion.

　　Performance specifications

　　Elite X3 has a 5.96 inches big screen, even in the flat the phone is rare. Its resolution is up to 2560x1440, compared with similar, although the pixel density declined slightly, but the actual loss of sharpness is not obvious.

　　HP Elite X3 to select an AMOLED Panel, so rather than the pixel density, you are more likely to be its vivid color and sharp contrast to attract. Elite screens X3 by a gorilla glass 4 protection, should do well in the scratch.

　　And other business machines, Elite X3 also stresses that protection. Its protective 810G military standard, actual performance does well--someone accidentally dropped it in the demo site, nothing. Elite X3 with IP67 waterproof performance, meaning leave it exposed to rain or water is no problem.

　　Waterproofing for Smartphone is not fresh, but HP's efforts also praise the: see the phone body, it fit right in, a strong sense of one.

　　As for other specifications, Elite X3 powered by Qualcomm Adreno 530 GPU, Yu Xiaolong integrated chip. Its battery capacity of up to 4150mAh, you can be charged via the USB-C interface. Its built-in storage space for 64GB.

　　Photos, Elite X3 with 16 million pixel camera and 8 million pixels front camera, taking pictures is great. Paul Frank case

　　Laptop extensions

　　Can make PC phone second Continuum features enough looking, HP is tailored for Elite X3 Mobile Extender. Mobile Extender and it looks like a typical laptop computer, with a 12.5-inch 1080p screen, touchpad and keyboard. However, no processor, GPU, memory and what not, all experience through the Elite X3 this phone using Miracast and WiGig technology to provide.

　　Unfortunately, HP Mobile Extender is not provided in this Assembly in the compactor. Light from the sample, its shape resembles Chromebook, particularly with respect to light and plastic. Compared with HP's traditional design, keyboard key travel is a bit short. However, this is a model.

　　Mobile Extender screen can be rotated by an l-shaped hinge, this will make the keyboard slightly raised, forming an angle to improve the typing experience.

　　Of course, Windows of 10 traditional Continuum function Elite X3 can do, this need is provided by HP Desk Dock base.

　　General comments

　　Move application Windows version 10 is now in an awkward situation--fewer consumers less optional equipment. HP Elite X3 in this case, brings superior performance and stunning new technologies.

　　However, excellent hardware design but not Windows Mobile version 10 's biggest problem: stalled the app store. Elite X3 is a very good phone, but it's not a Savior. Paul Frank

Panasonic Q no fan fan using aerodynamics, the air flow will move the ball in the side of the air intake air, outside air can be introduced, and then passes through the turbine to wind-blown at high speed. This design not only blowing out air, flat and straight, volume increased 7 times more, and blowing out air, flat and straight, can drive air circulation, temperature is more balanced.

Q there are five paragraphs adjusting, set three times, 18.5 w maximum power consumption, minimum 2.5 w. Crystal Red, champagne gold, Pearl White and 3 colors to choose from.
