Comprehensive interpretation of 4G network

1, what is the 4G network? How fast is 4G speed faster than 3G?

4 G is the fourth generation of mobile communication technology, it integrates 3G and WLAN in one, and can transmit high-quality video images and with High-definition television comparable. The popular point is that using mobile phones to surf the internet faster, the theoretical speed can reach 100Mbps, about 12.5mb/s. It is 2000 times times faster than dial-up, 3-5 times faster than the 3G we now use, and is comparable to WiFi. From this classic picture you can see the difference between 3G and 4G speed.

3G, 4G speed comparison

2, China Mobile 4G Network actual test network speed how fast?

At present, the three major operators have access to td-lte licences, but only China Mobile began to cover 4G network and commercial. Zol Mobile Phone Division has been for the 4G coverage of the Tsinghua Campus test, the actual 4G network to obtain 44Mbps, about the standard 4G speed of half 100Mbps.

Measurement of China Mobile 4G network speed

3. What are the domestic 4G network coverage areas? Is there any in the second-tier city or in the tourist area? 4G in the subway when will it be available?

Take China Mobile 4G as an example, at present, Beijing, including the south-east direction of the four ring and North five ring inside have covered 4G network, at the same time in Shijingshan, also Zhuang and Garden Bo Park also has a corresponding 4G signal coverage.

Shanghai is currently td-lte network coverage through Shanghai things, to achieve Lujiazui, Zhongshan Park, such as landmarks in the main urban areas and business district of the outdoor coverage. It is expected that by the end of this year the full coverage of the main urban area within the outer rim is completed.

The bus has also covered 4G.

Before the end of the year, in Hangzhou, Guangzhou, Shenzhen, Qingdao, Nanjing, Ningbo, Xiamen, Tianjin, Shenyang, Chengdu, Fuzhou and other cities will open 4G services, some areas of these areas will also have 4G signal coverage.

Note that the 4G network is currently not roaming, that is, you open the 4G business in Beijing to Shanghai 4G coverage area is unable to use 4G network, it will automatically for 3G and 2G network. At the same time, Beijing's major subway stations have not been opened 4G signal coverage of the notice, can not use 4G.

4, 4G network business and experience, China Telecom and the Chinese unicom what movement?

Although three operators have been licensed, but relative to China Mobile, Unicom and Telecom in the beginning of this year to start the base station construction, far slower than China Mobile, so the current Unicom and Telecom have no 4G experience of the movement, customer service also did not give a specific timetable.

Currently only China Mobile's 4G network started commercial, want to use 4G at the end of the year, currently only China Mobile family can choose.

5, Mobile 4G What package? How much is the minimum amount of money to use 4G network?

Mobile currently launched a total of 4 kinds of 4G packages, respectively, are internet traffic packages, fly-away packages, optional packages and data class terminal packages.

Exclusive package includes internet traffic and voice calls, divided into 138 yuan, 238 yuan and 338 Yuan three grades:

Fly to enjoy package

4G Internet traffic is a pure flow package, at the same time can be in 2G, 3G, 4G based on the stack, divided into 50-1805 files:

4G Internet traffic

Data class terminal flow rate is the basic package of 4G data class terminal. The original 3G data card charges users to replace the 4G data card and SIM card, must replace the 4G tariff, can be opened 4G function. User replacement of the 4G package is equivalent to change the package, effective next month.

Data class terminal traffic charges

And the Future China Mobile will also launch an optional package, 4G optional package from 4G Internet traffic, voice calls, data Services, three categories of tariff elements for the user free combination, but the current package of specific fee standards have not yet been introduced.

6, beyond the 4G package of traffic how to charge? 2g/3g/4g Flow packages will exist at the same time?

For China Mobile, the 4G network data tariffs from the previous 1 Yuan/m down to the current 0.29 yuan/m, that is, the flow rate dropped significantly. It is important to note that once the 4G package, the flow of the previous package must be canceled, so will not be the same 4G network billing 4G package, 3G network billing 3G package.

When users use mobile Internet, whether it is to use 4G or jump to 3G network is in accordance with the 4G package to charge, there is no separate billing situation. Of course, you can not handle 4G package use their original network package, but this is not capped 15 yuan flow of "North God Card" and other users are invalid, which some users want to use 4G must deal with 4G package.

7, 4G tariff dropped significantly, then I can use 3G mobile phone to use 4G card Internet?

A lot of people would like to have a big drop in internet costs, I can not 4G mobile phone and do a 4G card inserted in my 3G mobile phone use it? So you can get a lot of traffic, although not on the 4G network, but the price has been saved a lot, so feasible?

The author consulted the mobile business hall, customer service said 4G card can be used in 3G mobile phones, if you handle the 4G package business and do not use 4G network, so compared to the previous 3G fee is much cheaper, but there will be network, call instability phenomenon. If you don't mind, then go to the 4G card.

8, 4G Network so fast, my 4G package will soon run out?

4G The biggest feature is that the Internet fast, but will be a fast flow of consumption? This is about the situation we use. If you only use mobile phone to chat, the micro-letter basically changes little. The reason why 4G will appear a lot of traffic packages, is because our use of the environment has changed.

4G network speed Why the flow of large?

We rarely use mobile phone to watch video, now the network faster, mobile phone watching video load faster experience, which will encourage people to use mobile phone to watch video. Before watching the video is very card, has been in the buffer, see half everyone gave up, now a high-definition film can be in a few 10 seconds buffer, even if you do not see the final flow will be consumed in advance. The first time I took 4G to see the film, less than 10 minutes has shown that consumes more than 100 trillion traffic, although the film has just begun.

9, 4G Business How to do? Do I need to change the number of cards to change the phone?

At present, China Mobile has opened 4G Mobile card business, users to the hall without changing the number can be handled, but need to change the card and have a 4G mobile phone to experience the 4G network. After the purchase of 4G mobile phone, carry the original mobile phone SIM card to the designated business hall to replace the 4G card, the phone number is unchanged, and the transaction is free of charge, here we recommend that you finish the card at the same time to deal with a 4G Internet package.

10, at present those business Hall can handle 4G card?

Although the current mobile has opened a 4G Internet service, but not all the business hall under the line can handle 4G operations. Take Beijing as an example, Beijing Mobile main business hall and part of the branch office can handle 4G operations, such as in Xicheng District users can be in the moon, communications building, such as 9 Mobile office points for processing, other areas have not yet opened.

Business Hall can handle 4G card

If users want to know their peripheral has no 4G outlets can handle, you can call 10086.11, I am a contract machine users, the contract has not expired to handle 4G?

Contract users can also handle 4G mobile card, and other users like the contract users need to change the card and change the phone. Users first need to have a 4G mobile phone, and then replace the 4G mobile phone card.

Does the contract not expire to handle 4G?

All contracts for the duration of the contract continue, only the network speed from the previous 3G I converted to 4G, users can also increase the 4G traffic packet. Attention is due to the user has chosen the previous contract, so mobile office 4G mobile phone 0 yuan purchase business is not handled, so can only wait until the expiration of the contract before signing 4G mobile phone contract.

12, I am the north God card User, can I change 4G card?

Here explain "North God card", this is a 2G era 15 yuan monthly unlimited mobile phone card, but this business has been canceled, now can not handle. In addition to the North God card, other places have a variety of monthly unlimited mobile phone cards exist.

We mentioned that 4G also do not change the number, do not change the package, but after communication with customer service, because 15 yuan flow does not cap business has no longer handle, so want to use 4G must change the package, that is, North God card will not carry out "no change package" service, which means that users if you want to use 4G must be canceled the original package.

13, at present in China, what are the 4G mobile phones can buy? What are the contract machines?

Because the 4G network must be replaced by 4G mobile phones, so for users to choose a good 4G mobile phone and use 4G network is equally important, then the market sales of 4G mobile phone?

At present, there are a lot of 4G mobile phones, including HTC One Max, Cool Hornet, Samsung n7108d, Sony m35t, Cool Pie 8736, Huawei G716, Hisense X6t, ZTE U9815, Touch1, and other mobile phones have already supported 4G network and on sale.

4G terminals already on sale

The above mentioned models have been on sale in the business hall, while supporting 0 yuan purchase, if you are interested in a mobile phone, may wish to try these contract machines, the minimum monthly commitment to spend 188 yuan can have.

In addition to the above models of Samsung Galaxy Note3 and Galaxy S4, the LTE version will be on sale recently if you are a high-end user, you might as well wait for some of these models.

14, 4G version of the iphone 5s/5c when the sale of the iphone 5s/5c my hands can use 4G network?

The Wall Street Journal said earlier that China Mobile is expected to announce its distribution of iphones before and after the Guangzhou Global Partners Conference on December 18. This means that the mobile version of the iphone 5s/5c will come soon and will also support the mobile Td-lte network, iphone users can wait a second.

IPhone 5s can also use 4G

At present, the port version of the iphone 5s or the national line of the iphone 5s (model A1528) can support TD LTE network. In other words, the model for A1530, A1529 iphone 5s/5c, the country line model A1528 iphone 5s can support China Mobile 4G Network, users can go to the mobile business hall for crack use.

We need to replace a 4G Usim card in China Mobile Business Hall, according to the Chinese mobile announcement, users just take their original SIM card, directly to the business hall can replace the 4G Usim card.

15, I am Unicom and Telecom iphone5s contract machine users, I can use mobile 4G?

In the last question, we have answered the iphone 5s model which can use mobile 4G network in the national line, if your mobile phone model, then go to the mobile business hall to crack, after the success can deal with 4G mobile phone card and use mobile 4G network.

Support 4G cracked iphone5s Model 16, the current 4G mobile phones are very expensive, when there will be thousands of 4G mobile phone appears?

The domestic thousand-level market is a big space, but when 4G mobile phone can be reduced to the millennium level? At present, thousand Yuan 4G mobile phone is not far from us, from the mobile phone manufacturers and chip manufacturers to see next spring we will be in the market to see thousands of 4G mobile phones appear.

For chips, the 1088 LTE four core LTE chip, which includes the Gaotong 400 processor and Marvell, is intended to enter the 4G mobile phone market, and Marvell already has a mobile phone.

Manufacturers, such as ZTE, Cool faction and other domestic manufacturers have cooperated with Marvell to launch their own thousand 4G mobile phone, I believe it will soon be on sale in the market. If you want to buy a cheap 4G phone, consider these models.

17, 4G Mobile phone is still relatively few, the future 4G mobile phone will have a full network model? That is, mobile, unicom and telecommunications three operators 4G network can use mobile phones.

At present, Mobile, Unicom, telecom three operators have obtained the Td-lte 4G license, but the future telecom and Unicom will also obtain Fdd-lte license, so the future 4G network in China will be in two modes, if the whole network models, at least to support the Td-lte and Fdd-lte these two models.

Three network full support

Whether to support multi-frequency multimode mainly related to the chipset of the handset's modem, the Gobi modem used by the Gaotong's processor can be said to support the true 4G LTE global model, support LTE FDD, LTE TDD, WCDMA, cdma1x, ev-do, TD-SCDMA and GSM. Gobi 4G LTE Advanced with carrier aggregation speeds up to Mbps.

The current use of Xiao 800 processor Nubia Z5s Kte is such a full netcom to eat 4G mobile phones, the network is a comprehensive support td-lte, Fdd-lte, support 7-mode 14-frequency to become the current support network of the most widely used mobile phones. Future full network models will be more and more, users do not have to worry about what type of mobile phone they use.

18, 4G Network call quality drop is what?

After confirmation with customer service, 4G Mobile card does have a problem with the quality of the call, which is mainly due to the 4G network coverage is not very comprehensive, so if you are under the 4G network call, if inadvertently out of the coverage area, then the signal will automatically switch to 3G or 2G, this time will appear unstable phenomenon.

The decline in the quality of the call in the 3G when the beginning of the popularization of the time also appeared, currently for such a problem, China Mobile did not give the corresponding solution.

19, China Mobile 4G Network access point is Which?

Cmwap and Cmnet are just two GPRS access methods that China Mobile has artificially divided. The former is for mobile phone WAP Internet and set up, the latter is mainly for PCs, laptops, PDAs, such as the use of GPRS Internet services. They do not have any difference in the way of implementation, but because the positioning is different, so compared with Cmnet, Cmwap has a part of the restrictions, tariffs are also different.

Mobile 4G Network

So which is the access port of the mobile 4G network? After customer inquiries, the current user either choose Cmwap or cmnet can be normal use of mobile 4G network, in the access point 4G is indistinguishable.

20, China Telecom development Td-lte, need to include Td-lte and CDMA mode of multimode mobile phones, but there is no such type of mobile phone to achieve commercial, how China Telecom should develop?

A: At present, the Ministry has approved its 42 cities nationwide to carry out Td-lte scale network test, including TD-LTE/FDD-LTE/CDMA/TD-SCDMA/WCDMA/GSM 6-mode chip has been listed, Foreign countries have a variety of simultaneous CDMA and Td-lte mobile phone terminals. At present, China Telecom is concentrating its efforts to solve the problem of network interoperability of CDMA and Td-lte, which is expected to be commercially available in 2014 for China Telecom multimode handsets. Prior to this, it is understood that China Telecom will actively develop MULTIMODE data card business.

Through the above 20 questions about China 4G Network, I believe you can fully understand the relevant knowledge, with the development and popularization of 4G network, we will encounter more about the purchase of 4G mobile phones, replacement 4G mobile phone cards and the corresponding 4G network packages, the above solutions may help.
