It has been a while since I left the communications industry. After changing the industry, I slowly forgot the hardships of communication and the ups and downs.
The night before, I suddenly returned to my previous days of mobile communication (core network) technical support in the dream, returned to work 7*12 hours, carrying a notebook every day, no day (including Chinese New Year) can eat very safely, sleep day , returned to the previous year to travel more than 250 days.

"When the RNC signaling is interrupted, what should I do?" "Look first if there is a problem with the transmission. If not, try rebooting the module!" "No, no." "I will come up and see, you open the log switch!" The gateway has failed... ".." Switch to the standby module first!.. Don't be alarmed by the customer first..."
It turns out that I have been working in communication for ten years. How can this be easily forgotten? This has been deeply engraved into my bone marrow and my genes.
The communicator is smart, hardworking, diligent, and dedicated; giving so much, and asking for very little.
Just as my wife told me, "You can still write a little about communication, and you can show it to your children in the future." So I have the idea of ​​writing "Communication Ten Years" and recall some of my experiences, especially this one. The industry's enlightenment is shared with you.
First, industry analysisThe communications industry, in essence, I think of the second category of companies: operators and equipment vendors. The operators are mobile, telecommunications and China Unicom; there are nearly one hundred in the world. Equipment vendors currently have 5 people, all of which are global-level giants, E, H, A, N, and Z; these companies can basically provide a package solution from core network to wireless, IP, and transmission. There are also some technical content for doing billing and signaling analysis. Others are not worth mentioning, such as DT, FH, Gen. There are also small companies such as engineering companies, integration companies, labor outsourcing companies, and companies that offer low-tech accessories such as DDF shelves.
Terminal equipment manufacturers and SP manufacturers, software companies, etc., I think it is closer to the end users, is the consumer electronics format, and will not elaborate here.
The communications industry has experienced two major climaxes in China. 1 is the development of fixed networks in the mid-1990s, and 2 is the development of mobile communications around 2000. During this period, the communications industry experienced a leap-forward development. Everyone has a phone and everyone has a mobile phone. It has also spawned a large number of companies with very good benefits. Communication has established the concept of "high technology, high treatment" in the eyes of the public.
The communication industry has a relatively high demand for people. When I was in college, I and my neighbors felt that communication was harder to read than other professions. Also understand the hardware, but also understand the software, as well as the database, signal system, radio frequency, analog technology, digital technology; single math class on 7,8. After work, I feel that this industry is very difficult. It must be rigorous, careful, and not wrong, but also have perseverance and patience.
The communications industry has entered the 4G era from 2G and 3G, and the era of mobile office and entertainment has arrived. Almost everyone is enjoying the benefits of the communications industry, but few people understand the hardships and there are various XXs.
Second, the communication dilemma
The appearance of the communications industry has a "high-tech" light, and many parents are willing to send their children to study. In fact, the communication industry began to decline after the scenery of the mobile communication wave around 2000. The highly forward-looking H company has always proposed the "slogan of winter", and some people know it later.
Since 2005, the average salary increase of various communication companies has been basically difficult to outperform inflation; the operators’ brothers have reflected more and more things, and the number of people and wages has increased. Since 2007, various equipment companies have been on the rise. The news of the layoffs (the old one was eaten up). The indisputable fact is that the motorcycle was acquired by Google, Nortel was acquired by A, and A and L merged (currently there are many people inside A who mention L and bite their teeth, thinking that L dragged A), Siemens and N merged, and now they have withdrawn. There are also many small companies that are directly closing their doors. In an industry, there will always be many companies joining in the upward development; when the company goes downhill, there will always be companies withdrawing, may close down, may merge (to warm up?), and may withdraw. It is clear that the communications industry is in a downhill situation. I have been analyzing the reasons and analyzing them. Until I left, I dig deeper into the reasons. The so-called "I don't know the front of the mountain, only in this mountain."
I listed a few reasons why I personally summed up and common inside the industry, and then analyzed it one by one.
1) The wolf competition of H company (not the main reason)
2) The myth of TD is a ghost (an important reason)
3) Industry characteristics (primary reasons, will be specifically analyzed)
â— H company's wolf competition
First of all, I don't quite agree with this statement. But the industry is spreading, I will talk about it here. Company H is a company I admire and recognize, and I am always a rare entrepreneur in China who is respected by me. Company H has repeatedly sent me an invitation to join, for various reasons, did not go. However, it is undeniable that H Company is from a small private enterprise, and is currently the world's second-largest sales (and the first one), the world's leading communications equipment company with the first profit, and is involved in communications. Software, mobile terminals and other fields.
Objectively speaking, H Company broke the monopoly of foreign-funded enterprises and made the Chinese people proud in the world. The growth rate of their scale and profits has attracted worldwide attention. Just as "the test scores are not good, you can't blame the students for studying hard at night", you can't blame the decline and decline of the whole industry in a company. In the meantime, H itself is in good profitability, and it can only be said that other manufacturers are not competing. Of course, H's employees are extremely hard, and there are also "unusual XX", but in any case employees have the freedom to do and not. However, after leaving the communications industry, it was found that the competition in other industries was as much as communication, and many companies had more than H in labor intensity.
â— The myth of TD is a ghost
On January 7, 2009, the Chinese government officially issued a license for TD-SCDMA business to China Mobile. China Mobile has also started the second phase network construction of TD-SCDMA in 28 municipalities, provincial capital cities and planned cities in China. .
3G finally licensed, and soon after that year, China Unicom and Telecom also received 3G licenses for WCDMA and CDMA2000-EVDO.
Is 3G really running smoothly in China? In December 2013, the 4G license (TD-LTE) was released, which is obviously a slap in the face of China's 3G policy. In the case that the cost of 3G has not been recovered, the 4G license issued so quickly can only say that China's 3G policy has completely failed. At least China Mobile has lost confidence in TD (it is too obvious to turn the slap in the face, so the name is to develop 4G).
What is TD-SCDMA in the end? ?
If Baidu is concerned, there will be many results, what is the 3G standard for China's unique intellectual property rights, what smart antennas, and what technology is leading. . .
Let's look at the rate first:
CDMA2000EVDORevA downlink 3.1M uplink 1.8M;
WCDMAHSPA downlink 14.4M uplink 5.75M, and subsequent upgrades to HSPA+42M downlink;
TD-SCDMATD-HSUPA2.8M downlink 1.6M uplink.
TD-SCDMA is the slowest, and the actual test results can be felt by everyone. Unicom "Telecom" moves. Just look at which operator's 3G network card is sold well and know that the eyes of the masses are sharp. (In addition to the package, will someone pay for the mobile MIFI card??)
So what about the rest? Smart antennas, everyone knows that this is nonsense. Overlay, MyGod. Switch? It is far worse than W and C. High synchronization requirements and technical difficulties. Another fatal problem is that the industry chain is extremely immature. (Even if the technology is advanced, the industrial chain is not mature, it is not a negligible, even fatal shortcoming.) Equipment manufacturers can also force the production of orders, users can no one to accompany you to play, so there are fewer terminals. Therefore, Apple, Nokia (a few years ago is still very cattle) do not accompany you to play, Samsung pretending to cope with it, most of the TD is domestic manufacturers and cottage manufacturers.
As a consumer, are you willing to use a broken mobile phone with no face and a slow-moving network of so-called "Chinese intellectual property rights"? So, change operators! There are also many people like me who don't want to change numbers and don't want to use 2 mobile phones. Then 2G network uses å‘—, call and send text messages anyway, no problem, big deal with slow speed, no 3G.
In this way, a large number of people with sufficient spending power can not enjoy mature WCDMA or CDMA2000, and can only endure the speed of E or even G.
It is said that the high-level is really wise and vying for it. Finally, the mobile communication operators are integrated into three (why not four or two? Because of the three standards). The best W gives the weakest Unicom, C gives telecommunications, and takes care of the face of the American uncle; TD gives mobile, mobile is not "strong"!
Why is TD so weak "A Dou" hard to support? Why didn't the country ask everyone's computers to use Intel and AMD's CPUs, and forced to use "Godson" and "Hanxin"? (Just a joke here, Hanxin is a scandal of Shanghai Jiaotong University)
Is it for national security? No, this is not a "two bombs and one star", not a carrier, a nuclear submarine and a æ¼10 fighter.
Is it to support innovation? No, TD's core network signaling is "compatible" with WCDMA. To put it bluntly, it is a direct plagiarism. (Hello, change the name of IAM to IAM-TD, SRI to SRI-Chineseversion, and copy it too lazy too!!) ​​TD's wireless performance is very poor, even if it is innovative, it is not worth promoting "innovation" . (Note: TD-LTE has little to do with TD-SCDMA)
Is it to avoid patent fees? No, W is a European ITU standard and there is basically no patent hooliganism. However, at present, major equipment manufacturers have the right to speak in the ITU. No manufacturer will ignore such a large market in China and use expensive patent fees to set up barriers.
Such a technical indicator is poor, the industry is immature, and there are many standards of objection in various aspects. It is a matter of applying for a "patent". Why do you have to rush to launch a rush?
It is estimated that the senior management believes that the communications industry, especially China Mobile, is "big and big" and plays. Success is a great victory for "China's intellectual property rights" (the core network has no intellectual property rights?), and it is no big deal if it fails.
Such a sloppy, very unprofessional, many industry elites have long proposed the opposition to the TD's decision to go to the horse, and it passed.
Consequences:
1) Serious violation of the principle of “technology neutralityâ€. It shows that it is only mandatory for China Mobile to use TD. In fact, it is forcing China Mobile's 700 million users to use immature standards and cannot enjoy mature 3G****.
2) Seriously violate the criteria of “standardization of standards, survival of the fittestâ€. The current trend in technical standards is uniform, such as the TCP/IP protocol on the Internet. The two standards of GSM and CDMA in the 2G era have been criticized by many people. In the 3G era, there is still one more standard, and it is still an extremely immature and backward standard.
3) In order to wait for TD to mature, 3G will wait until 2009. WCDMA in European countries has been used for 5 or 6 years.
The above points have led to
1) The operator wants to buy W (or C), the user wants to use W (or C) but does not use it. China Mobile's network speed is low, so there are fewer people; Unicom's telecommunications network can be less. Since the communication industry chain is the user-"operator-" equipment supplier; users do not pay, so everyone is hungry.
2) More than one set of immature but main push standards for R&D, the cost of network optimization has also increased a lot.
3) The user waits for the daylily to be cold. Many applications that rely on 3G have also received a lot of influence, affecting a large number of communication peripheral industries.
â— Industry characteristics
The dilemma of the communications industry is closely related to the characteristics of this industry. Winning or losing does not matter. I summed it up, mainly because of the extreme decline, market direction and big ship problems.
1) Extremely weak
The communications industry was once very popular in the wave of fixed-line talks in the 1990s and the mobile wave around 2000. However, in recent years, the scenery is no longer and tends to sink. This is an inevitable trend in every industry. Do you know that the wages of textile factory workers in the early 1980s exceeded the bank? You know that taxi drivers make big money in the late 1980s. Do many people look for flight attendants as girlfriends?
Do you know that the steel mills in the 1990s must be able to enter the relationship? The civil servants are much more fragrant than the banks at that time.
Only this process of ups and downs has performed relatively fast in the communications industry, and it is more obvious.
In the 1990s, fixed-line telephones were installed. The mobile phone boom in 2000 was greatly helped by the communications industry for GDP growth and overall social efficiency improvement. Therefore, the country has also made great investments, and the entire industry is booming.
An old operator said to me that when I went to the phone in 1994, I would not go out after 3 o'clock every day. Going to the user's home to install, but also to give me a cigarette to drink money, what is like now, things are difficult to do money and less!
Obviously, the "good days" mentioned above cannot be sustained. The economic principle shows that when there is excess profit in an industry, there will be other competitors flooding into profits until the profits fall to normal levels.
The communication industry is like a rich boy who used to be a big boy in his childhood. When he was an adult, he fell in love with his family. When the snow is worse, the luxury habit has not changed.
What is even more frightening is that because the entire industry has been brilliant and too high-profile, so far many people in the society still think that the communication industry is "profiteering", so the rectification, blame, "to monopoly" voice is endless, the tariff is only down Does not rise. What is profit, profit = income - cost. The cost is low and the profit remains high. This is the truth of China Mobile's financial report. The cost of cutting is the hard-earned money of the suppliers and grassroots employees. The beautiful financial report has caused the impression of "communication and oiliness" to the society. It is really a glimpse of the leopard and the blind person.
It is true that there is an old saying, "Wu Xiu Yu Lin, the wind will destroy it." If you open a joke, you should really study the power system. The employees have a monthly salary of tens of thousands. The industry's losses require state subsidies, and the electricity prices have repeatedly increased. "Mourning and making a fortune" is far better than "scraping a face and filling a fat man".
Anti Reflection Film (AR film) is a widely used optical thin film used to reduce optical surface reflection and improve optical transmittance. It is widely used in electronic displays, solar panels, eyeglass lenses, photography lenses, and other fields to provide clearer and brighter visual effects.
AR film is a thin film material with high transparency and low reflectivity. It changes the propagation mode of light by coating a special chemical substance on the optical surface, thereby reducing reflection and improving transmittance. The main function of AR film is to reduce the reflection loss of light on the optical surface, allowing the observer to see the details of the object more clearly, while improving the brightness and contrast of the display screen.
AR film has a wide range of applications in the field of electronic displays. In liquid crystal displays, LED displays, touch screens, and other devices, AR film can effectively reduce the reflection of ambient light, improve display performance and visibility. It can prevent problems such as flickering, blurring, and glare in the image, allowing viewers to use electronic devices more comfortably.
In addition, AR films are also widely used in solar panels. Solar panels typically need to absorb as much sunlight as possible and convert it into electrical energy, but the reflection of light can lead to energy loss. AR film can reduce the reflection of sunlight on the surface of solar panels, improve the absorption rate of light, and thus improve the efficiency of solar panels.
In the field of eyewear lenses, AR film can reduce surface reflection, improve transparency and visual clarity. It can avoid glare and interference, providing a more comfortable visual experience. In addition, AR film can also prevent dirt and fingerprints on the surface of glasses and lenses, making them easier to clean.
In summary, Anti Reflection Film (AR film) is a widely used optical thin film used to reduce reflection on optical surfaces and improve transmittance. It has important application value in fields such as electronic displays, solar panels, eyeglass lenses, and photography lenses, providing users with a clearer and brighter visual experience.
