The most popular view on the supply side reform of

  • Detail

Looking at the supply side reform of the communication industry from volte, is video calling really a product worth talking about? Is it really a selling point that you can boast about when you talk

if you use iPhone 6/6s (plus), you may receive an operator setting recently

it is volte

at the recent Xiaomi 5 new product launch, Lei Jun also took volte as an important selling point

a discussion on volte has been opened in the industry. Today, let's also talk about volte. 1

1. What is volt

voice over LTE is an IP data transmission technology. It does not need 2g/3g, and all services are carried on the 4G network. It can realize the unification of data and voice services under the same network

in other words, the 4G network can not only provide high-speed data services, but also provide high-quality audio and video calls

II. What are the characteristics of volte

volte technology brings 4G users the most direct feeling that the connection waiting time is shorter, and the voice and video call effect is higher quality and more natural

it is fundamentally different from 2G and 3G voice calls. Volte is an end-to-end voice scheme based on all IP over 4G networks

1. Higher voice quality. Due to the adoption of high-resolution codec technology, the voice quality based on 4G network can be improved by about 40%. In short, there will be a qualitative leap in call perception. Do you remember the amazing perception brought by Ben when he just launched the call function? Volte is more magical than that

2. Lower access delay. Volte brings users lower access delay. In the 2G era, the call connection time is long, and the elongation at break of ordinary polymer materials is usually between 50% and 100%, usually about seconds. In the 3G era, it is at least seconds. In the volte environment, the call connection time is about 2 seconds. Simply put, it is connected faster, 50% lower than 3G

Its proprietary high-performance polymer 3D printing material windform XT 2.0 has passed the screening outgassing test of the European Space Agency (ESA)

3 Higher connection rate. In 2G and 3G networks, we often encounter dropped calls. In the volte environment, the dropped call rate is close to zero, which means that the call success rate is greatly improved

to sum up, volte brings users a clearer, faster and more efficient call experience

for example, if the 2G era calls are like ordinary green trains and the 3G era is an express train, then the 4G era calls are more like aircraft or high-speed rail. It brings a completely new experience and a qualitative leap

III. why do operators deploy volte

for operators, deploying volte means opening the road to the evolution of mobile broadband voice

in the long run, this will bring great value to operators: improve wireless spectrum utilization and reduce network costs

for voice services, the spectrum utilization efficiency of LTE is far better than that of the traditional system, reaching more than 4 times that of GSM, that is, the same spectrum resources can generate 4 times of revenue

for China Mobile, there is a more practical problem. Although the voice service still brings great economic value to the enterprise, it is an indisputable fact that the voice service is slowing down or even declining. The value of 2G network has reached its peak. How to migrate the voice service from 2G network has become an urgent problem

what is more embarrassing is the 3G network. The TD-SCDMA network invested and constructed by China Mobile has always been controversial in the industry, especially in terms of return on investment

spectrum resources are the basis for operators to survive, and are also directly related to the construction cost of operators. The low-frequency spectrum means stronger penetration, that is, operators can build deeper and wider networks at the same cost

for the network scale of China Mobile, this undoubtedly means a lot of investment. How to make the limited spectrum resources play a greater role is a very serious and realistic problem

IV. why do users choose volte

this question is more interesting than the previous one

this is good and that is good. The user's choice is really good. Recalling the products and services launched by operators in recent years, how many users really pay for them

in the external publicity, we see that the volte experience is significantly better than the traditional CS voice. The introduction of HD voice and video codec has significantly improved the communication quality. The call connection time of volte is greatly shortened. Seamless integration with RCS can bring rich services. However, are these really what users need? Do users care

a typical case is HD video call

as early as the 3G era, China Mobile has vigorously promoted that users can connect via video under the TD network. The same product has once again become a publicity hotspot under 4G and 4g+ networks. However, the reality is that although the scene setting of video call seems beautiful, only a few people actually use video to contact

even those that attach great importance to user experience have video functions, but the utilization rate is not ideal

I think there must be some special reason behind this

in the traditional era, the communication market is more like a seller's market. Although it also says that it is customer-centric, in fact, users do not have much choice. Operators use their capabilities to drive the market. The base station is the money printer, which is the famous saying of that era

in short, users have to use whatever the operator has

up to now, the channels and tools for user communication have been greatly enriched, and the selection cost has been greatly reduced. Users can enjoy the same or even better services on different channels with their fingers. The homogeneous communication services among operators and the heterogeneous penetration of Ott enterprises have made the market competition extremely fierce. The status of buyers and sellers in the market is very different from that in those years

in short, what the user needs is what the operator provides

therefore, in such a market environment, operators may really think about what users need and care about? Is video calling really a product worth talking about? Is it really a selling point that you can boast about when you talk? (how many people will talk at the same time)

v. may it be some digressions

as an aside, I have recently paid attention to several live broadcast products. Although I am very confused, I still have a new understanding of the business of anchor. Some fight for beauty, some fight for humor, some fight for sincerity, some fight for emotion, and even some people fight for boredom

well, anyway, live video applications are undoubtedly a new upsurge in the 4G era, and even a cultural phenomenon. I once asked a young anchor: what is the experience of being an anchor chatting with a group of strangers every day, After all, there may be a group of stingy guys drooling at the screen. As a result, the anchor's answer made me happy. You will know if you open a live broadcast

yes, the user demand in this era is no longer the result of research and guidance, but more at a special time: +886 ⑶ ⑵ 654349 Fax: +886 ⑶ ⑵ 654388

it's like live broadcast. I wonder why we can't take advantage of the good performance of volte to package a product for live broadcast applications. New fire-retardant materials are emerging

well, maybe this is another kind of self high. After all, what we say may be wrong

back to the point, from the publicity of volte, communication operators really need a supply side reform
