The birth of a product is inevitably a struggle through various trade-offs. How much of the designer's and user's thoughts can be focused together is the reality and imagination required by each. Although sensory evaluation has a set of standards for each industry, you can use equipment to measure how good the indicators are. However, everyone's experience in life and social experience are quite different. If you don't care about this product, it will vary from person to person. Sound, image, taste, I think there is a certain degree of synergy between them. Just as girls love to take selfies, most girls may feel like they are using beauty tools to grind the skin and make up their makeup. They will not care about the so-called details, light and shade, color... This is the case, the demand is not the same. I remember that my wife's graduation design was to do the sensory evaluation of yogurt, and various test tubes in the laboratory's refrigerator were used to cultivate different flavors of yogurt. Specifically how to cultivate, fermentation I naturally do not work. However, in terms of taste, taste, too thick to suck, too sweet not like yogurt, slippery and not greasy, this is what I think is delicious yogurt. What about the taste of X5iii? The sound quality of X5iii is worthy of this price, and it is unrealistic to think of a leapfrog PK. After all, it is a penny. The X5iii's voice is still relatively neutral and slightly warmer than the old X5 or X7 before, and the overall sound is soft and comfortable, and the mid-footset. It is not too pompous to modify the sound. (In fact, I think this is the whole band for the processing of sound details), and the softness still retains a very good resolution. The low frequency is full and the dive is deep enough. I think the shortcomings are a bit slower. The first feeling of the midrange vocals was to scratch the ear than the previous flying arrogance, and the separation of vocal instruments was inferior to the X7. To give an example that is not appropriate, it is like adding a filter to the picture. It blurs the skin a little, and if the detail edge is obvious, the harmonics are not too rich. The high frequency is a soft way, and the compromise is a little compromised. However, the overall tone is not too dark and will not be confused with a pan. Generally speaking, it is more suitable for listening to fashion. Compared with X7, in fact, the style difference is still very obvious, X7 resolution is more violent, better separation, more dynamic, more sharp. X5iii is like another musical experience, more popular, younger and more comfortable. The appearance of the X5iii I think is the continuation of the X7 design, the screen size is the same as the X7, the body is more compact. After all, flying propellers are not a company known for its industrial design, but I feel that they are changing and trying to give you a good product while doing it more beautifully. Objectively speaking, the appearance is still decent. System control, Android system brings a wealth of application access, there are many mature APP. Bluetooth, Wifi users want to connect extensions are provided. Although there are still some BUGs, the system will be more and more stable through the improvement of the firmware. And more and more surprises come. Feiao is a manufacturer who is willing to absorb the opinions of users and can't wait to plug everything you want. Yan value has improved, fast charge has, double card slot has, balanced output has, the filter mode is open, Bluetooth wifi... The last sound is also decent, oh, this kind of product you will feel very intimate. Everyone wants to do a good job. Obviously, their own requirements are a bit too high, but you will admire this company to do the product. However, in fact, in detail, the more the shop is opened, the harder it is to do it. The flaws on the X5iii above make it even more exciting for Feiao to work on the next product. The ideal and the reality are doomed to make appropriate trade-offs. The X5iii is not the best player in this price range, but it does have its own unique competitiveness. Finally, I would like to say a few questions that people are more concerned about: There is a sonic boom in the song. The AK4490 DAC will have a popping sound when switching wav and DSD. This situation is known to the other manufacturer's discussion group. The actual use of the X5iii does experience occasional slight popping noises. Before listening to other manufacturers to talk about, they are doing mute processing, that is, when the switch between songs and songs to do the circuit's mute, the sound mute out. This later firmware should improve. The bottom noise of the Bal Balancing mouth is indeed there, not surprisingly, remember to be slightly more than the N5, does not affect the normal volume listening songs. It feels similar to the X7 under AM3. What is 5G CPE? Wireless Cpe,4G Cat6 Cpe,Mifi 4G,Ufi 4G Shenzhen MovingComm Technology Co., Ltd. , https://www.movingcommiot.com
Definition of 5G CPE
CPE stands for Customer Premise Equipment. The so-called front end refers to the equipment in front of the customer's terminal equipment. When we use Wi-Fi, if the distance is far, or there are more rooms, it is easy to appear signal blind spots, resulting in mobile phones or ipads or computers can not receive Wi-Fi signals. The CPE can relay the Wi-Fi signal twice to extend the coverage of Wi-Fi.
What are the benefits of CPE?
Through the following comparison table, it is not difficult to understand the technical advantages of CPE products:
* Currently, the global 5G FWA service is mainly in the Sub-6GHz band, with only the United States and Italy supporting the millimeter wave band.
* 5G CPE integrates the low cost of Wi-Fi and the large bandwidth of 5G, combining the advantages of the two to form a strong complement to traditional fiber broadband.
The relationship between 5G, FWA and CPE
It can be said that FWA (Fixed Wireless Access) will be the most down-to-earth application of 5G technology. FWA business plays a key role in enabling "connecting the unconnected." FWA is a low-cost, easy-to-deploy flexible broadband solution. Compared with wired access technology, FWA has been an ideal choice for deploying broadband in many countries and regions because it does not need to obtain rights of way, dig trenches and bury cables, and drill holes through walls. The development of 5G technology is further promoting the development of FWA.
FWA services (including 4G and 5G) have reached 100 million users. FWA is no longer a niche service; The FWA industry as a whole has been supported by numerous suppliers. Why is that? In the 5G era, 5G CPE receives 5G signals from operator base stations and then converts them into Wi-Fi signals or wired signals to allow more local devices to get online. For operators, the initial user penetration rate of 5G is low, and the investment is difficult to realize quickly; The CPE business can use the idle network to increase revenue for operators, so major operators vigorously promote the development of 5G CPE.
FWA services can be used for both home (To C) and business (To B), and customers have different requirements for CPE devices when using FWA services in different application environments, resulting in consumer grade 5G CPE and industrial grade 5G CPE (similar to home routers and industrial routers).
In 2020, the global market size of 5G CPE will reach 3 million units, and it is expected that in the next five years, the market size of 5G CPE will maintain a compound growth rate of more than 100%, reaching 120 million units in 2025, with a market value of 60 billion yuan. As an important market for 5G CPE, China's 5G CPE market size will reach 1.5 million units in 2020 and is expected to reach 80 million units in 2025, with a market value of 27 billion yuan.
The difference between 5G CPE and other devices
CPE can support a large number of mobile terminals that access the Internet at the same time, and the device can be directly inserted with a SIM card to receive mobile signals. CPE can be widely used in rural areas, cities, hospitals, units, factories, communities and other wireless network access, can save the cost of laying wired networks.
A Router is a hardware device that connects two or more networks, acts as a gateway between networks, and is the main node device of the Internet. Routers use routes to determine the forwarding of data. If it is a home router, it does not support a SIM card slot, and can only receive signals by connecting to optical fiber or cable and then convert it into WI-FI to provide a certain number (several) of terminal devices to surf the Internet.
Industrial 5G CPE is equivalent to 5G industrial routers, and the technology of the two is not very different. On the one hand, the industrial 5G CPE converts 5G network signals into WiFi signals for transmission, and on the other hand, the data received by the WiFi network is converted into 5G network signals for uploading. In addition, industrial 5G CPE generally supports routing functions.
5G CPE trends
According to a research report, after evaluating the products of some mainstream 5G CPE suppliers, many institutions believe that the development of 5G CPE products will continue in two aspects: one is to support mmWave and Sub-6 GHz at the same time; Second, the design will pay attention to humanized operation and installation. The industry development trend will accelerate the demand for 5G in the medical, education and manufacturing industries due to the epidemic, and 5G FWA will promote global 5G CPE shipments.
