When will the FDD LTE license be issued

Hello landlord, as early as December 2013, the Ministry of Industry and Information Technology issued a TD-LTE standard 4G network to three operators, and at the end of June 2014, the Ministry of Industry and Information Technology approved Telecom and Unicom to carry out hybrid network trial operation, and then there are various rumors that the FDD-LTE license is going to officially arrive, and the result is that the bamboo basket is empty, so that many users are happy.

However, the recent news about FDD-LTE license has made new progress, according to a number of insiders from China Telecom and China Unicom, two operators hinted to Tencent Technology, the Ministry of Industry and Information Technology has received two applications submitted to carry out FDD-LTE-related business, and the final approval is underway, and the specific approval time is most likely to be within three days, that is to say, the issuance of the license is likely to be within these three days.

And some operators said that from the attitude of the Ministry of Industry and Information Technology, it is very likely that this issuance will be issued, most likely on the 15th, but it is not ruled out that the time will be changed temporarily. At the same time, China Telecom officially announced yesterday that it will open Tianyi 4G business to the whole country, and launched innovative products in the industry that use traffic free voice, that is, users can get a minute of voice when they buy a trillion traffic, as far as telecom practices are concerned, FDD-LTE license is indeed close at hand, otherwise it would not be so hyped to open up 4G services to the whole country.

Having said that, but there is no guarantee that there will be no bounce this time, after all, there are too many such things, but in terms of time, the FDD-LTE license should indeed be issued, but whether it will be as the news said this time, let's wait and see, of course, I hope this is true, after all, for users who are looking forward to the FDD network, time has been waiting too long.

Hello, first of all, thank you for your support to China Telecom. According to your description, there is no specific time for the issuance of FDD-LTE licenses, but China Telecom TD-LTE has already started commercial use, and you can use the network to access the Internet first. You can continue to pay attention to the latest developments on the official website of the Ministry of Industry and Information Technology or the online business hall of China Telecom.

China Telecom 4G has been officially commercialized, if you need to check 4G tariffs, check bills, pay phone bills, and buy mobile phones, please log in to Anhui Telecom's online business hall. Have a great day!

Hope mine is helpful to you and can get yours!

LTE FDD and LTE TDD are two network modes for 4G LTE that are used for paired and unpaired spectrum, respectively. LTE is a globally accepted standard that includes two network modes: FDD and TDD. The two models are essentially the same, with only minor differences.

The choice of FDD or TDD depends only on what kind of spectrum an operator has, so there is no superiority or disadvantage between the two. Globally, many operators will deploy both networks in the future in order to take full advantage of all the spectrum resources they own. And our national 4G LTE development adopts FDD TDD converged networking, which is at the forefront of the times in this regard.

There are only minor differences between the FDD and TDD modes in the LTE standard, with a 90% similarity. Due to factors such as the difference in wireless technology, the different frequency bands used, and the interests of various manufacturers, the standardization and industrial development of FDD-LTE are ahead of the 4G standard that has become the most widely adopted in the world and has the most abundant terminal types.

TD-LTE has a downlink rate of 100 Mbit/s, an uplink rate of 150 Mbit/s, and an uplink rate of 40 Mbit/s.

Compared with the LTE FDD system, the LTE TDD system can better support different types of office rough and rough services, and will not cause waste of resources.

The LTE TDD system also has an incomparable advantage of LTE FDD, that is, the LTE TDD system can coexist with the TD-SCDMA system. For existing communication systems, the current data transmission rate can no longer meet the growing needs of blind users, and operators must plan in advance for the smooth evolution of existing communication systems to B3G and 4G systems. Since the LTE TDD frame structure is based on the frame structure of TD-SCDMA in China, it can easily realize the coexistence and fusion of TD-LTE system and TD-SCDMA system.

Difference between LTE-FDD and LTE-TDD:

The difference between these two systems, as well as their respective advantages and disadvantages, is that because TDD is on the same frequency band, Qiyin can make better use of spectrum resources and is easier to arrange;

FDD is carried out in different frequency bands at the same time, so the data transmission capacity is stronger, but it also has higher requirements for spectrum resources! In today's increasingly tight spectrum resources, this is a painful thing for all operators.

If the theoretical downlink speed of FDD will be faster, this makes many potential 4G users excited, and make up their minds to use Unicom's LTE-FDD, in fact, the quality of a network does not depend on the theoretical speed, but also depends on the coverage quality, user carrying capacity, actual transmission speed, etc. After all, the ideal is full, and the reality is the backbone. After large-scale commercial use, the user usage is large, and the actual downlink bandwidth is estimated to be half a catty, no matter how wide the road will have morning and evening rush hours, the same reason, no matter how wide the bandwidth is, it can't withstand large-scale seeds**.

One hour and one frequency division, each with its own strengths.

The speed is not comparable to TD-LTE... Too far behind to catch up with...

LTE: It is a global standard developed by the 3GPP organization based on Orthogonal Frequency Division Multiple Access (OFDMA) technology, including FDD and TDD modes for paired and unpaired spectrum. There are only minor differences between the FDD and TD modes in the LTE standard, with a 90% similarity.

FDD: FDD (Frequency Division Duplex) is one of the two duplex modes supported by this technology, and the FTE using FDD (Frequency Division Duplex) is FDD-LTE. As a requirement of LTE, the evolution of the TD system is synchronized with the evolution of the FDD system.

The vast majority of enterprises' contributions to the LTE standard can be used in the same way as FDD and TD modes.

FDD-LTE License:

FDD-LTE is one of the world's two major 4G standards, which is earlier than TD-LTE, with more mature technology and more abundant terminals. TD-LTE is suitable for hotspot area coverage, and FDD-LTE is suitable for wide-area coverage.

On December 4, 2013, the Ministry of Industry and Information Technology officially issued 4G licenses to the three major operators, and China Mobile, China Telecom and China Unicom all obtained TDD-LTE licenses.

It is a business license, which means that it can prove that the FDD-LTE network can be commercialized, and it cannot be used commercially without this license.

The two licenses are different and are issued separately for LTE's two modes, LTE TDD and LTE FDD. LTE includes FDD and TDD network modes, which are used for paired and unpaired spectrum, respectively. The two modes are essentially identical, with only minor differences in duplex mode.

The world's spectrum resources are limited, and in order for operators to make full use of their spectrum resources, both FDD and TDD licenses are required.

As far as the development of our country is concerned, Wang Xiaochu, chairman of China Telecom, has said that TD-LTE will be used to cover the hot spots with dense services in the city, the suburban junction with business needs but the regional transformation is not mature, and the rural affluent areas that are in the process of urbanization but do not have fiber to the home. The LTE FDD will cover the main urban area of the city and some of the most developed county towns, 4A level and other important scenic spots. In fact, the development direction of FDD TDD converged networking will gradually be popularized around the world.

Today, 1,011 of the 2,123 LTE TDD commercial networks are being rolled out by operators who have already deployed LTE FDD networks.

FDD is the world's most common 4G standard, the world's most complete industry chain, the most mature standard, and the most blind and disadvantageous network among the optional types of mobile phones.

This is the mainstream of the future.

The Ministry of Industry and Information Technology will not issue FDD licenses to mobile companies.

The Ministry of Industry and Information Technology can give mobile FDD licenses at will, just like China Unicom and China Telecom. However, the move got a pile of waste paper.

Like the 4G that China Telecom and Unicom were forced to use TD, FDD and TD 4G are completely different basic equipment. The same goes for moving to FDD.

Because the TD system is a network standard with independent intellectual property rights, the Ministry of Industry and Information Technology first recommended TD, so at the beginning, only TD licenses were issued, but this is very unfair to Unicom and Telecom, they invested more money than mobile, and almost all basic equipment had to be repurchased.

This is the fundamental reason why China Unicom Telecom 4G started to deploy the network much slower than mobile.

Similarly, this is also the direct reason why the Ministry of Industry and Information Technology later issued FDD licenses to China Telecom and Unicom. After all, the transfer of the network requires large investment and low efficiency.

China Mobile will issue FDD licenses, but will only issue FDD licenses to Unicom and Telecom. If you really don't want to change your number, it is recommended to change to a cheap and practical mobile phone that supports TD-LTE. Or change the number, you say that it is troublesome to change the number, it is estimated that there are many important contacts and businesses.

It's up to you to weigh the deficit.

China Unicom's FDD-LTE license was officially obtained on February 27, 2015.

On the afternoon of December 4, 2013, the Ministry of Industry and Information Technology officially issued a 4G license, and China Mobile, China Unicom and China Telecom each obtained a TD-LTE license.

On February 27, 2015, the Ministry of Industry and Information Technology officially issued FDD-LTE 4G licenses to China Unicom and China Telecom.

So far, China Mobile has TDD 4G licenses, and China Unicom and China Telecom have TDD and FDD 4G licenses.

TDD LTE is China-led, wahaha

Break it down:

The currently issued TDD-LTE is an evolution of the 3G TD-SCDMA standard. The TD-SCDMA for 3G is undertaken by China Mobile. At that time, it was not due to the backwardness of technology, but due to the immaturity of the industrial chain, the most prominent thing was that the available terminals, especially the mainstream high-end terminals such as iPhone, had very little support, which led to the complete failure of this technology.

At present, TDD-LTE is issued first, instead of a mature FDD-LTE, which is also necessary to protect the country's own intellectual property rights and mature the industrial chain. The issuance of FDD basically has to wait until TDD-LTE is basically matured, and it can compete with FDD-LTE in the early stage of the industrial chain.

From my personal judgment, the FDD-LTE issuance time is about another 1 year. China Mobile and China Telecom need to basically mature the terminal industry chain in this year ((Unicom's 3G is very good, so in fact, the interest in LTE-TDD is not very high).

Of course, the true timing of FDD issuance may not be 100% certain at the moment, and may even include current national industry decision-makers. The final distribution time needs to be given according to the interests of all parties in the industry, and the decision-makers weigh the pros and cons.
