What is the difference between China Mobile 4G Data Card and 4G Data King?

1. Differences

All 4G networks have the same speed. The difference lies in the amount of traffic and the usage range of the traffic.

The 4G traffic card is national traffic, including voice. The 4G traffic king is the local card, which also has voice, but the traffic is small and the monthly fee is low. Its traffic is 224M domestic traffic, and 800M is The total free time traffic in the province is 1G.

2. Detailed introduction

1. Mobile "4G data card"

The monthly package fee is 50 yuan, including 2GB of national data, and the voice fee is for local calls, Long-distance and roaming charges are 0.2 yuan/minute, and domestic calls are free. The package does not include caller ID fees. If you need to activate the function, there is a 5 yuan/month fee.

2. Mobile "4G Traffic King"

The monthly rent of the package is 30 yuan, including 500M of domestic 2/3/4G general traffic, and 2/3 of 2G within the province are given free of charge every month /4G general (leisure time) traffic (free for 12 months). Within one year after activation, there are a total of 2.5G general traffic and 200 text messages per month, compared with the 20 yuan upgraded 4G package launched at the end of May (20 yuan includes 300M traffic).

The 4G Data King package, which can have 2.5G traffic for only 30 yuan per month, seems more attractive. In addition, this package also activates the automatic traffic overlay package function outside the package by default. Users who exceed the package traffic will be charged at 0.29 yuan/M. When the amount of traffic outside the package reaches 10 yuan (corresponding to 35M out-of-package traffic), 65M domestic general use will be automatically given. Traffic, repeat the above billing process after the free traffic is used up.

Features and advantages of 4G

1. Fast communication speed

Since the original purpose of people studying 4G communication is to improve cellular The most impressive feature of 4G communications is that it has faster wireless communication speeds as phones and other mobile devices wirelessly access the Internet.

2. Wide network spectrum

In order to achieve 100Mbps transmission in 4G communication, communication operators must carry out substantial transformation and research on the basis of 3G communication network in order to The communication bandwidth of the 4G network is much higher than that of the cellular system of the 3G network. According to executives from AT&T, which studies 4G communications, it is estimated that each 4G channel will occupy 100MHz of spectrum, which is equivalent to 20 times that of the W-CDMA 3G network.

3. Flexible communication

Strictly speaking, the functions of 4G mobile phones can no longer be simply classified into the category of "telephone". After all, the transmission of voice data is only a 4G mobile phone It is just one of the functions. Therefore, in the future, 4G mobile phones should be regarded as small computers, and 4G mobile phones will have even more amazing breakthroughs in appearance and style.

Future 4G communications will allow people not only to communicate anytime and anywhere, but also to download and transfer information, pictures, and videos in both directions. Of course, they can also play online games with strangers they have never met. There may be the worry of being permanently locked by the online positioning system with nowhere to hide, but compared with the convenience and security brought by the map it provides, this is simply negligible.

4. High intelligent performance

The fourth generation of mobile communications is more intelligent, which is not only reflected in the intelligent design and operation of 4G communication terminal equipment, such as menus and The reliance on scrolling operations will be greatly reduced, and more importantly, 4G mobile phones can achieve many unimaginable functions.

5. Good compatibility

In order for 4G communication to be accepted by people as soon as possible, not only its powerful functions should be considered, but also the basis of existing communication should be considered, so as to allow 4G communication to be accepted by people as soon as possible. More existing communication users can easily transition to 4G communications with minimal investment.

Therefore, from this perspective, the future fourth-generation mobile communication system should have global roaming, open interfaces, interconnection with multiple networks, diversified terminals, and smooth transition from the second generation. Features.

6. Providing value-added services

4G communication does not evolve from a simple upgrade based on 3G communication. Their core construction technologies are fundamentally different. 3G mobile The communication system mainly uses CDMA as the core technology, while the 4G mobile communication system technology draws the most attention from the orthogonal multi-tasking frequency division technology (OFDM).

7. High-quality communication

Although the third-generation mobile communication system can also realize various multimedia communications, the future fourth-generation mobile communication system is also called "multimedia mobile communication". Communication.

The fourth generation of mobile communications is not only to respond to the increase in the number of users, but more importantly, it must respond to multimedia transmission requirements, and of course, communication quality requirements. It must be able to accommodate the huge number of users in the market, improve the existing poor communication quality, and meet the requirements of high-speed data transmission

8. High frequency efficiency

Compared with the third generation mobile communications. Technically speaking, the fourth generation mobile communication technology uses and introduces many powerful breakthrough technologies during the development process. This effectiveness allows more people to do more things using the same amount of wireless spectrum as before. And when doing these things, the speed is quite fast. Researchers say that the download rate may reach 5Mbps to 10Mbps.

9. It is cheap.

At the same time, when building a 4G communication network system, Communication operators will consider adopting a gradual introduction method directly on the infrastructure of 3G communication networks, which can effectively reduce the costs for operators and users. According to researchers, certain aspects such as wireless instant connections of 4G communication. The service fee will be cheaper than 3G communication.

For people, the future 4G communication does seem very mysterious. Many people think that the fourth generation wireless communication network system is the most complex one ever invented by mankind. It is true that there are a lot of troublesome technical problems in the implementation process of the fourth-generation wireless communication network, which probably will not surprise people at all. There are many technical problems in the fourth-generation wireless communication network. It is related to the Internet, and it will take several years to solve it.
