Young good - Charm Blue Note 5 get started

1 Introduction

From the very beginning of its creation, the Meizu brand has given me the impression of being niche and sophisticated. From the first contact with the Meizu M3 music player to the successive launch of the mobile phone product line, Meizu's industrial design has always been unique in its class, so I once saw in him even a little Apple's shadow. In spite of this, Meizu has been tepid in the domestic mobile phone market, and its popularity is not very high, it is also very puzzling. This year, the Meizu seem to have begun to exert force, crazy launch of the sea tactics, once or twice a month concert (product launch) one after another, people overwhelmed. This can not help but give me doubts, in the background of the new machine launch frequency is so high, Meizu can bring us products with bright spots. Next, I will open mystery for everyone through my first public test experience.

2, out of the box

Charm Blue Note 5 uses a simple white box, the front only printed product name, very consistent with Meizu's style.

On the side of the box, the words “youth good quality” reveal the positioning of the product.

Open the box and take a picture of the family. Nothing to say, it is still a cell phone, charging head, data lines and card pin, instructions. No headphones, no surprises.

3, product appearance and details

Charm Blue Note5 front is still using the waist round home button that has been used in recent years, and the rim is decorated with chrome, which is very delicate. The fingerprint sensor is integrated on the home button and is similar to the iPhone design. Compared with fingerprints on the back, individuals feel more comfortable with front-facing fingerprints. In actual use, the fingerprint recognition speed is very fast and the user experience is good. I forgot the location of the thousand yuan machine. In addition, the home button can be used to achieve different functions by touching or pressing, which is very convenient.

The top of the front is the light sensor and distance sensor, the earpiece, and a 5-megapixel front camera, from left to right. Although there is no integrated design for the hammer mobile phone, the open hole of the sensor is not at all on the front black panel. Conspicuous, but if it is on other white panel models. . . The picture is too beautiful to think.

The edge of the screen adopts the popular 2.5D arc shape, which increases the feeling of sliding and holding. The screen is very black in the information screen state. The whole front of the phone is integrated. This is the legendary aesthetic of the information screen.

Lighting up the screen, the 5.5-inch 1080P fully-fitted screen with a narrow frame design of 3.66mm is very amazing, 71.63% of the screen share makes me accustomed to using a fruit machine. 401's PPI makes this screen display delicate, brushing Aunt Zhang to feel happy again and again! I am very satisfied with this screen!

The back of the phone is a 1300w pixel camera and a dual color temperature flash. The color of the back I got was a starry sky, but I felt a little pale purple and it was very nice to see.

The upper right side of the fuselage is the volume control button and the lock screen button. Good workmanship, no obvious loosening. In actual use, the feedback of these key presses is quite simple.

The upper left side of the fuselage is a sim card slot. The Charm Blue Note5 adopts dual card dual standby full Netcom mode, Cato can install a nano sim card on the inside part, relying on the external part can choose to install a nano sim card or a tf card for capacity expansion. , Up to 128G capacity, very user-friendly.

At the top of the fuselage is a handset.

The bottom of the fuselage openings are dense, from left to right are followed by 3.5mm headphone jack, microphone, micro USB interface and three waist-round speaker openings, coupled with two screws, this design is really good. In this era of popular TYPE-C interface, the Charm Blue Note 5 still using the micro-USB interface is a bit out of date.

Charm Blue Note5 uses an integrated metal body, the border at the CNC process cut out a circle of chamfered bright edges, angular, for the whole machine to add a ray of masculinity.

Because of the use of 18W fast charging technology, the charging head is very large, the data line is also very thick, with a full range of materials, the actual use of 4000mAh large-capacity battery can be filled for almost an hour and a half, quite good. It can be said that fast charging technology is the best partner for large-capacity batteries. Imagine that if you give you a large battery of 10000mAh, you will be able to fill it with a full day, and it will be very useful. . .

4, performance

Charm Blue Note5 as a thousand Yuan machine, performance certainly can not be comparable with high-end models, I am psychologically prepared for this. First look at the configuration, I Note4 is the 3G RAM + 32G ROM version of this hand, the CPU uses MediaTek Helio P10 eight-core processor, still with QUALCOMM missed. The display core GPU model is Mali-T860.

Looking at the values ​​of these parameters, the friends must be a bit guilty. Let's go to the "unwilling to run a minute" link.

Let's look at the rankings again:

Congratulations to Charm Blue Note 5 for taking the throne of the 50th place. Successfully suppressing Note 3 that I haven't grabbed, I was moved.

But to be fair, although the performance is general, but through the use of this time, it is enough for me who do not play games, brush Zhang Aunt, chat WeChat, brush microblogging are not strenuous feeling, very smooth.

4, the system

Charm Blue Note 5 factory system is based on Android 6.0 Flyme 5.2 system, rather than the latest Flyme 6.0, a little regret. However, officials claim that they will be able to upgrade to 6.0 in the near future and need to wait patiently. Since the Flyme 5.2 launch time is also quite long, the majority of machine friends are already very familiar with, I simply pick a few individuals think there is a characteristic write.

The UI aspect of the system is still familiar, and it has adopted a flat style that has become popular in recent years. However, the shapes of the icons are different and seem a bit messy, lacking in beauty, and personal feelings.

The calendar and clock icons are dynamic and will be updated in real time.

It comes with an easy-to-use mode for large fonts that is suitable for older moms and dads.

Pull-down menu options are abundant, including WIFI, mobile traffic and Bluetooth can also be further selected by clicking on the lower triangle below, very convenient.

Support floating ball function, you can set the floating ball opacity and customize each gesture corresponding to the function, very flexible and autonomous. And there is one more point, the suspended ball will not appear in the picture when the screen shot, this is better than the fruit machine.

Support split screen operation, the split screen application display ratio can be arbitrarily adjusted, so that you can use one.

This is relatively awkward, even built-in grab red plug-in, big Meizu too understand the needs of diao silk. . .

5, camera performance

Charm Blue Note5 equipped with a 1300w pixel cmos, the actual camera performance in general, slower focusing speed, color is too oily, night performance mediocre, the value of the camera has certain requirements may not be acceptable. However, after all, the price is there and I can't ask for too much. Let's look at the proofs directly.

6. Summary

As a thousand Yuan machine, Charm Blue Note overall is worth the money. After all, the price of the product is there. It cannot be perfect in every aspect. Through personal experience during this period, I solemnly made the following evaluation of this phone.

advantage:

1, beautiful appearance: appearance of this kind of thing benevolent, I feel pretty good, a variety of color, slim body, large screen ratio, simple design style made me impressed.

2, exquisite workmanship: This is reflected in the integrated metal body, mTouch button, CNC trimming, volume and lock screen keys.

3, screen: 1080P full fit screen, 401PPI, fine quality, color performance is not bad.

4, large battery + fast charging technology, mothers do not have to worry about I did not bring charging treasure.

5, fingerprint recognition speed is amazing.

6, Flyme system: This needless to say, interactive friendly, feature-rich, there are many small features are very practical, it is important that there is no advertising, a lot stronger than the friends.

Disadvantages:

1, camera too slag, this point I think is Charm Blue Note5 most dragged back one of the legs.

2, slightly weaker performance, MTK processor has been criticized for a long time, 3G RAM may be tight later.

3, did not use the popular Type-C interface.

In general, for me who do not play games, in addition to the camera dragging their legs, this phone can fully meet my daily needs, and then look at the beautiful price, but also nothing to force the.

I hope this assessment will help the majority of valued friends. Thank you!

  • This paper discusses the key technologies in 3G/4G/5G (third generation/fourth generation/fifth generation) communication systems, and then discusses the differences in the antenna technologies adopted by them. After reading and studying a large number of papers on the key technologies of 3G/4G/5G communication system, here I make some analysis and summary of my own. With the rapid development of science and technology, mobile communication technology has undergone profound changes, from 1G to 2G, to 3G, and then to 4G and 5G. On December 4, 2013, the fourth generation of mobile communication 4G technology was officially operated in the Chinese market, which means that China's mobile communication industry has entered the 4G era. At this time, research institutes in various countries and world-renowned enterprises engaged in communication technology research have entered the research and development of the new generation of mobile communications, namely 5G (fifth generation mobile communication system). No matter which generation of communication system, the research technology is to analyze the characteristics of wireless communication channel to overcome the noise interference. A lot of researchers are now looking at Massive MIMO technology. How is it different from the antenna technology used in 3G/4G communication systems? Will it become the core technology of the next generation of wireless communications? 1 Key technologies of 3G/4G/5G Communication System 1.1 Key technologies of 3G Communication System Since the early 1990s, the mobile communication industry began to actively study the standards and technologies of the third generation of mobile communication. In January 2009, China's Ministry of Industry and Information Technology issued 3G licenses to China Mobile, China Telecom and China Unicom, indicating that China entered the ERA of 3G mobile communications. The third generation mobile communication system mainly includes WCDMA, CD-MA2000 and TD-SCDMA. Its key technologies include: A. Rake receiving technology; B. Channel coding and decoding technology; C. Power control technology; D. Multi-user detection technology; E. Smart antenna; F. Software radio. 1.2 Key technologies of 4G Communication System In December 2013, China officially entered the era of 4G (fourth generation mobile communication system) communication network. In 4G mobile communication system, OFDM(Orthogonal frequency Division multiplexing) technology is adopted. OFDM technology is due to its spectrum utilization

    14 years focus on antenna research and development, production, sales, 30,000 strength of the factory, 600 people production capacity, the main sucker antenna, glass fiber reinforced plastic antenna view details & GT;

    It is widely regarded as high rate of 2 and good anti-multipath fading performance. In the future, RESEARCH related to OFDM technology will also be carried out in 5G communication networks. The main key technologies of 4G communication system include: a. OFDM technology; B. MIMO technology; C. Multi-user detection technology; D. Software radio; E. Smart antenna technology; F. IPv6 technology. China's Ministry of Industry and Information Technology has just issued 4G licenses to the three major operators, and they are still deploying their networks on a large scale with a small number of users. At this time, China Mobile said it will start the RESEARCH and development of 5G communication system. Analysts pointed out that the three major operators are participating in THE RESEARCH and development of 5G, one is to keep up with the changes of The Times, and the other is that the demand is faster than the technology development. Li Zhengmao, vice-president of China Mobile, said at the 2014 MWC in Barcelona: "China Mobile will fully support the development of 5G projects, hoping to lead the industry in THE development of 5G technology and the setting of technical standards." With the deepening of mobile communication technology research, the key support technologies of 5G will be gradually defined and enter the substantive standardization research and formulation stage in the next few years. The jury is still out on what core technologies will be used in the future. However, I have compiled a list of nine key technologies that have been the focus of discussion in various high-end mobile forums. A. Large-scale MIMO technology; B. Filter bank based multi-carrier technology; C. Full duplex technology; D. Ultra-dense heterogeneous network technology; E. Self-organizing network technology; F. Use of high frequency band; G. Software-defined wireless networks; H. Wireless access technology: (1) BDMA (Beam Split multiple Access technology)

    3 (2) NOMA (Non-orthogonal multiple Access technology) i. D2D (device-to-device) communication. Figure 1 is the layout of Massive MIMO antennas in 5G communication networks. I am studying Massive MIMO technology in my lab. Figure 1 shows users communicating with each other centered on a large-scale antenna. The performance of wireless communication systems is mainly restricted by mobile wireless channels. Wireless channel is very complex, and its modeling has always been a difficult point in system design. Generally, statistics are made according to the measured values of communication systems in specific frequency bands. Wireless fading channel is divided into large scale fading channel model and small scale fading channel model. The so-called large-scale fading model describes the field intensity variation over a long distance (hundreds or thousands of meters) between the transmitter and receiver, and reflects the rule that the received signal power changes with the distance caused by path loss and shadow effect. A small scale fading model describes the rapid fluctuations of the received field intensity over a short distance or time. The large scale fading channel model is caused by the influence of the surface contour (such as mountains, forests, buildings, etc.) between the receiver and the source. The small-scale fading channel model is caused by the multipath effect and doppler effect. If there are a large number of reflected paths but no LOS (direct signal) signal component, the small-scale fading is called Rayleigh fading, and the envelope of the received signal is described statistically by the Rayleigh probability density function. If LOS is present, the envelope is subject to Rician distribution. Multipath effect phenomena cause flat fading and frequency selective fading.
