2017 new Apple Apple iPad unboxing comparison ipad pro
Originally wanted to wait until the new ipad fell to 2300 to buy, but as the Mother's Day is approaching, feeling temporarily hopeless, and in the Jingdong 2399 activity price orders.
domestic
Apple Apple 2017 iPad 9.7-inch Tablet PC 32GB2399 yuan 2017 new iPad, three-color optional, straight down a good price. Jingdong specials to 2399 yuan shipping, three-color optional, but also superimposed 12 period interest-free coupons, in addition to Jingdong Apple Super Brand Day there are other products to choose from, although not the lowest price, but most of them can start with the price, there are Need to be able to see step by step. Compared to the same 9.7-inch iPad Air2, the 2017 9.7-inch iPad upgraded the SoC from A8X to A-value 401 reviews. 734 Collection 305 Direct Links View Details Really do not know what ipad evaluation, write unboxing it. Last year ipad pro photos are taken well, do not know where to write, today is a simple comparison with the new ipad good. The new ipad is a gold model, ipad pro is a silver model.
Jingdong's packaging is so simple. The boxes are all crashed.
Ipad packaging has not changed recently, ah, the appearance is similar, it can be seen on the side which is a paragraph.
Positive contrast, did not see the difference.
On the back, the same is true at first glance, the difference is on the camera. The new ipad has no flash, and the camera is flat with the back. The ipad pro's camera is protruding, with a flash. The back of the mic hole, the new ipad in the middle, ipad pro on the camera side. I also didn't take the habit of taking pictures with the ipad. The flash was superfluous to me.
Looking at the bottom edge, the position of the horn hole is different.
On the left side, you can see another mic hole of iPad Pro. Volume keys, new ipad can be divided, press up is also softer.
The top edge, you can see the advantages of ipad pro - the other two speaker holes, but did not correspond with the bottom edge position. The other mic of the new ipad is in the middle of the top edge.
On the right side, the new ipad bare, ipad pro is the mouth of a keyboard.
The two ipads are discharged together and it can be seen that the new ipad is obviously thick. No wonder the camera does not protrude.
Is not a system difference, ah, ipad pro can set "true tone", that is, will turn the screen a little yellow.
For me to just play a little game to see the video, the two ipad configurations are enough. However, ipad pro should be lighter, and there are speakers on both sides, it is still a little advantage. As for the ipad pro access to the keyboard that port, such a small screen next to the keyboard, ah, 9.7 pro do not set this mouth, drop the price is not good.
LTE CAT4/CAT6 Definition
The full name of LTE CAT is LTE UE-category, which is broken down to explain :LTE refers to 4G LTE network, UE refers to user equipment, and Category is translated as level. Smooth interpretation is the level of 4G LTE network transmission rate that user devices can support, which can also be said to be a technical standard for 4G network speed. Therefore, LTE CAT4/CAT6 means that the user device LTE network access capability level is 4 or 6.
Since the level is different, then its capabilities are certainly not the same, let's take a look at LTE CAT4/CAT6 affect what performance, respectively, what level. Simply put, LTE CAT affects the upper limit of 4G LTE uplink and downlink network speed, which is generally referred to as the maximum upload and download speed that a user device can achieve.
There are not only 4 and 6 levels in LTE CAT, but the table above is our list of currently known LTE CAT levels and the corresponding maximum transmission speed. Among them, LTE CAT4/CAT6 is also the current network transmission technology level of 4G mobile phones, while the faster CAT7 and CAT8 are still in the laboratory stage and have not been commercially developed.
Phones and chips that support LTE CAT4/CAT6
As far as the current 4G mobile phone market is concerned, most mobile phone products are CAT4 technology, and only a small number of new mobile phones use CAT6 technology, such as Huawei Honor 6, Samsung Galaxy S5 advanced version and LG G3 Cat6, and the concept of LTE CAT6 is proposed by Huawei Honor 6.
For the mobile phone LTE CAT4/CAT6 standard, it is directly linked to the mobile phone chip, or, if you know the processor of the mobile phone, you know which technology the mobile phone uses. For the current 4G mobile phone chips, only Huawei Kirin 920 and Qualcomm Snapdragon 805 processors for LTE CAT6, before this 4G chips are LTE CAT4, the future and Kirin 930, Qualcomm Snapdragon 808/810 will support LTE CAT6. Mediatek won't have LTE CAT6 chips until the second half of next year.
Qualcomm Snapdragon 805, 808, and 810 also support LTE CAT6
It is worth mentioning here that Qualcomm Snapdragon 805 and Kirin 920 are not the same in chip design, the LTE CAT6 baseband of Snapdragon 805 is an external Gobi MDM9x35, while Kirin 920 is a direct SoC integration, and the chip is integrated, this point Kirin 920 has ultra-high integration. It has certain advantages in power consumption and cost. As a leading international communications company, Huawei's strength can not be underestimated, but also the pride of our people.
The actual use value of LTE CAT6
Upload, download speed is our use of mobile Internet access the most concerned performance, but it should be clear that the LTECAT standard is the 4G transmission speed limit, and can not improve the transmission speed, in the operator's 4G network speed has not reached the next standard, simply raising the limit is meaningless. At present, the 4G networks of domestic operators are all LTE CAT4 standards, and the peak download speed is 150Mbps, but it is difficult to reach the upper limit of LTE CAT4 in practical applications, and even to reach 100Mbps is very difficult, so at this stage LTE CAT6 has no use value.
In terms of real life applications, LTE CAT6 is not as beautiful as we think. We can do a calculation, according to the formula 1MB/s=8Mbps, the maximum download speed of LTE CAT4 is 18.75MB/s, such a download speed, for 1080P video online playback has no pressure, even 4K online film source still can not occupy such a large bandwidth, So LTE CAT6 has no use either.
To sum up, LTE CAT6 does not have much use value at this stage, and the term is only a gimmick of manufacturers, until the operator 4G standard reaches LTE CAT6, I believe that LTE CAT6 equipment has long been popular. So as for whether the phone is LTE CAT4 or LTE CAT6, you don't have to care.
