Editor’s note: This article is from WeChat public account Zijinshan Technology (ID: zijinshan2013), author Lu Toushe, 36 氪 Published with permission.How to make full use of the relevant advantages of radio and television and combine with the current related industries, and then create a new 5G market and business, China Radio and Television and related industry partners face together.Radio and TV 5G has a new episode.The cooperation plot between the “previous episode” and State Grid has not subsided, and many people have commented on it as speculation by brokers.In the beginning of 2020, the Ministry of Industry and Information Technology issued a license for the 4.9GHz frequency band. Combined with China Mobile’s 5G frequency resources, many official media took the lead in releasing the “new episode” conjecture: the cooperation between radio and television and mobile entered into negotiations to jointly build 5G.Or will form a 2: 2 confrontation with China Unicom.Radio and TV, which “relied on satellites first, then on cable, and later on boxes,” has yelled “to be formally commercialized by 2020”.Although the cooperation with China Mobile has been speculated for a long time, once the frequency resources come out, on the one hand, there is no network burden of traditional telecommunications operators, and on the other hand, radio and television without the experience of wireless network construction, who will use this power to complete this?5G goals?In the 20 years of radio, television and mobile marriage history, the audio and video advertising market that originally belonged to radio and television has been preempted by the Internet and telecommunications operators. From the integration of the three networks to the integration of media, radio and television have been trying to break the mystery of OTT competition.In the 3G era, the radio and television department used its broadcasting standard to launch a CMMB mobile TV service for mobile phones. It even broadcasted nearly 3,800 hours of Olympic games during the 2008 Beijing Olympics. After that, it cooperated with China Mobile to become the standard for its 3G mobile phone collection.There are many endless CMMB terminals.However, due to the one-way broadcast, the program was limited, and the mobile phone at that time was not good enough in terms of screen and video experience. After a small-scale development, the operator, China Broadcasting Corporation, merged into the State Grid and was stopped in 2016.I remember I took a friend ’s car, and he was watching a car CMMB TV when I was waiting. As soon as I got on the car, I said, 呦 This is a CMMB TV, and he also said immediately, Emma, ​​I can understand people.I explained to many people that it was unclear.After 2009, from 3G to 4G to today’s 5G, network speeds have increased hundreds of times. Audio and video have long become the protagonists of network traffic, and video clarity has become higher and higher, as well as various programs.Source, attention, on-demand, barrage, all kinds of gameplay let users truly participate in the carnival of streaming media.As stated in a report from the IT Times, if radio and television did not adhere to their own CMMB standards, but adhered to the concept of win-win cooperation and merged their own content advantages with the network and technical advantages of telecommunications operators, it may be possible todayIt will be a different situation.Even if the business model is still singular for various reasons, in the 5G era, how can a licensed radio and television company give up the opportunity to resurrect its TV business resources?But the premise is to make a big plate of 5G network.”It is necessary to find a strong strategic partner. Radio and television have a high 4.9GHz frequency. Continuous coverage of 5G requires more base station investment. At present, radio and television do not have sufficient capital, technology and talent, and they have no experience to form a 5G network independently.Building a 5G network with China Mobile is a pragmatic option. “In response to such rumors, Yang Guang, research director of Strategy Analytics, said in an interview with Zijinshan Technology that the State Grid has always had the idea of ​​entering the communications field for many years.It is not necessarily completely groundless.The cooperation between SVA and China Mobile has also been passed on for many years and has been renovated repeatedly.The so-called 2: 2 pattern is reasonable from the perspective of avoiding repeated investments.”But from the perspective of market competition, I am afraid that Telecom and China Unicom may not accept it frankly. After all, the two of them still have difficulty in fighting against mobile. Will the other party add another broadcaster that has mastered the low-frequency spectrum and content resources, will it be too imbalanced?In other words, if a 2: 2 pattern is to be formed, what kind of compensation needs to be given to the Union? These are not very clear. “Yang Guang admitted.And Wu Chunyong, the editor-in-chief of the converged network that has always been rooted in the radio and television field, told Zijinshan Technology that China Mobile and China Radio and Television cooperate to build a 5G network. If we only analyze and judge the rationality from the perspective of complementary technologies and industrial operations, it is not comprehensive enough.Factors such as core resource allocation must be fully taken into account.How about the golden 700MHz drama?The condition of strategic cooperation is reciprocity. Radio and TV’s own 700MHz resources are the biggest weight of its 5G cooperation.”700MHz has actually been enabled by many countries in the LTE era, and the coverage effect is very good. This part of China’s spectrum has always been in the hands of radio and television, and has not been invested in wireless communication networks.” “700MHz, a base station covering a radius of 5 kilometers is not a problem.It can be used as a basic coverage network and can also be applied to some IoT applications. This frequency band can be used to complete wide area coverage with minimal investment. It is very valuable. The three major operators have always been jealous of this frequency band.Very. “The hot comments of netizens in the industry also reflect the” golden “characteristics of the radio and television 700MHz spectrum.Some media have calculated that using a 700MHz frequency band to build a national 5G network requires less than 1 million base stations, while the three major operators need to build 6 million 5G macro base stations based on higher frequency bands to achieve 5G coverage.”It is impossible to build four 5G networks in the countryside, two will be enough, one for mobile, and one for broadcasting and television at 700M, and the telecom will be free.” Some technicians claim that filters and PA-based equipment can support 200MHz bandwidth.Therefore, two operators with adjacent frequencies can share the same network equipment, and China Mobile can also help radio and television to build a 5G SA network with rich experience.However, there are also comments that it is unlikely, but the co-construction of the 4.9GHz band is of little significance. Unless the radio and television are willing to share the 700MHz band, the radio and television are definitely not willing.In this regard, Yang Guang said: “The 700MHz may be similar to 4G in the experience rate, but it is still of great significance for operators to quickly form national coverage at a lower cost. In particular, industry applications, such as transportation and logistics autonomous driving, all requireBased on a relatively complete network coverage, the rate may not be very high, but perfect coverage is absolutely needed. So if the 700MHz spectrum should be the first target of any potential partners of radio and television, if the radio and television does not take out 700MHz, it is estimated that it will notSomeone will cooperate with him. “The most famous technology that takes advantage of the characteristics of 5G networks is Messive MIMO (large-scale antenna technology), but 700MHz can not support Massive MIMO because of its low frequency band, large wavelength, and large antenna array.This is also the reason why many people think that mobile broadcasting and television cooperation has a play: if the low frequency 700MHz of radio and television for 5G can only solve universal coverage, and 4.9G in the middle frequency band can only achieve point coverage, the advantages of 5G cannot be exerted at all, soHigh-capacity coverage with China Mobile.And China Mobile’s FDD frequency is too small, which is very unfavorable for the development of new low-latency services in the future, but the 2 × 30M FDD frequency of Radio and Television also happens to be very much needed by mobile.In this regard, Wu Chunyong said that in terms of technical advantages and disadvantages, the frequency bands such as 700MHz and 4.9GHz must have their own strengths. A single frequency band cannot meet the future 5G applications and business scenarios. The combination of multiple frequency bands will naturally followTechnical, user and other needs emerged.Now that the radio and television has obtained a 5G license, it is one of the 5G participants, so it is naturally one of its missions to use the 700MHz band of the cable television network operator for 5G wide coverage construction.After all, 700M uses FDD (frequency division) when constructing 5G, and the current 5G network construction of the three major operators uses TDD (time division). FDD has a significant reduction in delay compared to TDD, which is sensitive to many delays.The business is very favorable, which is also one of the differentiated advantages of cable network operators in 5G.From another perspective, Yang Guang gave a new interpretation: in the consumer market, there should be no particularly large demand for 4.9GHz frequency band coverage in the short term.China Mobile has stated that the 4.9GHz spectrum can be used as “local spectrum for the public network” and is more suitable for industrial markets, such as campus networks.”In this case, it should not be so important, or not urgent, to merge radio and television spectrum. The real value of China Mobile is definitely 700MHz.” New 5G, how new?On January 9th, China Mobile launched the collection of 17 city 5G SA core networks involving 2.5 billion yuan.Although 5G killer applications that have driven the 5G replacement wave have not yet appeared, and industries and industries have just begun to figure out how to use 5G to implement private network upgrades or business reforms, it is clear that operators are working harder on 5G networks than 2019.Radio and TV’s 2020 goal is not easy to achieve based on the fact that it has no experience in wireless network construction: it is necessary to carry out personal business and industry vertical applications on an independent 5G network at the same time; in 2021, it is necessary to build a radio and television 5G network into positive energyA new 5G network with wide connectivity, universal access, new applications, good services, and controllability.”Regardless of who you work with, the core issue of radio and television is the effective internal integration. If you can’t achieve the integration of a nationwide network, you can’t achieve effective operation and market competition in the short term with anyone, but may leave room for external forces.Collaborate with various provincial networks of radio and television to break through opportunities. Effective full-network integration depends on high-level political will, which is beyond the scope of the industry. “Yang Guang proposed a deep analysis of how radio and television implement 5G.In terms of opportunities, Wu Chunyong expressed optimism: In the face of this rare round of 5G construction and development opportunities, no matter who China Radio and Television’s future strategic partners are, its business operation model in the 5G field will certainly be essentially related to the three major telecommunications companies.Operators realize differentiation.With the maturity of technologies such as 3G / 4G / Fixed Broadband, it has also spawned and promoted the vigorous development of many applications including e-commerce, network video, O2O, short video, etc. At present, autonomous driving, artificial intelligence, 8kWith new technologies, for a young 5G industry participant such as China Radio and Television, it is very fortunate that he is standing on the shoulders of giants to carry out the 5G industry layout, and how to make full use of the relevant advantages of radio and television and related to the presentThe combination of industries has led to the emergence of brand-new 5G markets and services, which are jointly faced by China Radio and Television and related industry partners.At the end of last year, the Ministry of Industry and Information Technology officially issued the “192” paragraph to China Radio and Television, which means that China Radio and Television has obtained basic paragraph support in mobile communications operations.Some people in the securities circle also said that China Radio and Television has the number segment resources, and it also has the qualification to transfer numbers to the network. It does not rule out that it will adopt various types of marketing and discounts in the future, and borrow the number transfer policy from the three major operators.Acquired.It’s not impossible..
