Development of the SIM card industry in the world
First look at the data analysis, from 3.3 billion global users in 2007 to 3.8 billion last year, this year estimated 4.2 billion. Global mobile users are still growing globally. What is the amount of SIM card here? Of course, all global users have a number of CDMA phones, most of which are useful SIM cards. However, in terms of global procurement volume, the global SIM purchase in 2008 was 3.1 billion, which can be seen as not a complete digital rating for SIM cards and ordinary users. Many times users are constantly changing their own numbers and SIM cards, so the purchase amount of SIM cards is very large. It is estimated that the SIM card win-win situation will be 3.5 billion this year. In 2013, it will provide 5 billion cards per year.
Asia Pacific and China location in the SIM card industry
In the global SIM card industry, the Asian SIM card is getting stronger. For China Mobile, China Mobile's SIM card purchases accounted for one-fifth of the total in 2008 and 2007. It is a relatively important influence on the SIM card and the entire industry and capabilities of the SIM card. Now SIM card capacity, in fact, the current SIM card is relatively limited if it is only as a network. Probably in 2008, 64KSIM cards accounted for about 50%, and there are higher capacity cards. When we talk about this, we can see a trend. The amount of users is actually growing, and the demand for telecom cards is actually increasing. The status of China and Asian markets is rising, and the capacity of cards is increasing. From around 2003, China's SIM card is afraid of diversification in various provinces, and the management of SIM cards needs to be resolved. Therefore, around 2003, China Mobile teamed up with various partners to make China Mobile's OTA system, enabling remote management of SIM cards in China Mobile's entire network, including application data, including information-on-demand menu updates. There are also some software updates and so on.
Since 2007, there have been higher requirements for the capabilities of SIM cards, including the fact that in 2008 China Mobile Research Institute united some partners and terminal manufacturers to make large-capacity SIM cards. Here its capacity ranges from the original K to the Z or even the G. In 2008, 128 MB SIM card was developed, and the function of the web browser was implemented on the card. By 2009, there will be higher requirements for SIM cards. For example, in 2009, China Mobile Research Institute was also a joint partner, like the USDP used in ICBC and CCB, so it is more used on the mobile Internet. application. There is also a major credit card change. In 2009, China Mobile put the RFID antenna in the SIM card for the first time in the world, realizing a SIM card without terminal. For example, you can buy movie tickets, tickets for next year's World Expo, as well as the business of the card, as well as the business of access control. These are all implemented in the credit card, and the antennas for incoming communication are integrated, and can be optimized to truly achieve business. The level of this is China Mobile's work in the field of SIM cards.
In the Internet of Things industry, it is a bit narrower, what is the development status of the SIM card industry for machines. In fact, in the online world, the current network, there are 338 million Internet users in China, and 680 million for mobile, or Chinese mobile phone users. The network has become an indispensable means in this network, but our communication has not been fully established. For example, a million cars will be idle for 10 minutes on the road and will consume 140,000 liters of gasoline. There is also a relatively extensive domestic irrigation method that will cost 85% of China's water resources. These are all talking. We face a challenge. We need to communicate with the road, we need to talk to the rice field, and we need to talk to the object. Things to do in the Internet of Things to achieve this goal. First of all, the IoT industry is very widely used. In fact, experts introduced in the morning, such as transportation, electricity, agriculture, urban supervision, as well as in the home and environmental protection, can use the Internet of Things. For example, in terms of animal traceability, there are some initial attempts in the Internet of Things in certain places in China, as well as in certain cities and certain industries. For example, let the food in the supermarket tell people its history, making it easier and safer to eat food. Like a remote meter, it can transfer data to the backend center itself, which saves manpower. There is also positioning navigation, as well as the sturdy (transliteration) of the car. It allows people to know the car's operation anytime and anywhere, so as to achieve true driving worry and security. Waiting for these applications, the SIM card actually plays a very important role. Have a SIM card to allow communication between objects to be transmitted over the network.
From the above data, before and after 2009, the use of the SIM card in the machine industry can see two kinds of information. Firstly, it is mainly used in three industries, power, vehicle, transaction, or Said that wireless POS is more. There is also a tendency to see a trend, and its growth trend is still relatively obvious. Of course, the development of this industry so far is still in its infancy. There are more than 3 million terminals so far, and some of the terminals have implemented the WMMP protocol. Some SIM cards are pre-installed at the terminal. Overall, the development of the Internet and technology are still in their infancy.
The demand for SIM cards in the Internet of Things environment
The communication between people, the demand for SIM card is more at the software level. In the current Internet of Things environment, it puts forward a demand for it, and more is to generate some hardware platform, software platform and packaging process requirements in the industrialized environment. There is also the communication of things and things in the case of the Internet of Things, and its distribution process will produce relatively large changes.
For example, the platform for hardware and software, why is it a platform for hardware and software, not just a hardware platform. Here are some points mentioned here. For a data save time, this card will take longer to save data. The average SIM card storage time in the mobile phone is about 10 years, and it takes longer to maintain in industrial or special industries, ten years, fifteen years or even higher. In addition, there are also the number of insertions. The cards used in the Internet of Things are different from the cards used in mobile phones. The normal number of mobile phones can be turned on and off every day. The normal insertion of the SIM card is only the power on or off. At the time; but in the field of machines, in the field of Internet of Things, its demand changes more, and the number of insertions is very high. In fact, we have already felt in some industry feedbacks now that the quality of SIM cards in this area is also relatively high. There is also a corresponding speed, its reading, and anomalous exploration. For example, it can be detected at very high temperatures to tell the software inside the SIM card. This includes the impact on the chip, including the impact on the design of the program. There is also a demand for more, the impact of the packaging process, in fact, the ordinary SIM card packaging process uses PVC materials, it will not meet the current industrial requirements. For example, the requirements for earthquake resistance, in the car, or in extremely harsh environments, the card of the terminal will constantly vibrate, which will lead to some poor contact, and the seismic requirements are more intense. There are also specific requirements for temperature, humidity, antistatic and so on. In addition, from a security point of view, the requirements for anti-theft. It has also appeared that cards placed in the machine will be stolen and appear in human communication.
Another big demand for SIM cards is about personal management, which is about the remote card issuance system, or the requirements related to the card issuance process. Simply put, this card was originally purchased by China Mobile. Who is it to purchase? Will purchase from China Mobile buyers. What to buy? Will be given to the point of sale and then sold to individual users. This process has changed throughout the IoT industry. For example, the real demand department is from a specific industry, and the industry generally has the possibility to talk with China Mobile, and it is also possible to find an integrator. Here he will have relevant requirements to integrate the relevant SIM card. When integrating the relevant SIM card, he will propose it to China Mobile. China Mobile will also find the corresponding manufacturer to make it, and the whole process will change. An important requirement is that many times this number, or when you own this SIM card, you don't know which hand it will send, but when you actually use it, it is not in a province with the card you made at the time. I need the same network. There is also a need for the card to be in the machine for a long time to be enabled, etc.
What is the China Mobile solution in the face of these demands? China Mobile's research on SIM cards in the current environment has started last year. This year, combined with the standards of many industries and combined with many current needs, unified production, to plan the entire SIM card technology and related indicators. Currently used in the IoT-class SIM card, we call the plug-in SIM card. This SIM card is the same as the normal SIM card model. This benefit does not change the existing distribution process, but the chips inside will require higher, higher temperature, higher humidity, and higher new energy requirements. On the other hand, plug-in SIM cards can not meet the requirements of some special industries. At this time, there is another SIM card soldered to the module. The benefits of this SIM card can be better to prevent vibration first. On the other hand, its anti-theft effect will be better, and the card will be more compact. That is to say, in the case of miniaturization of the current module, a card is better to be put in, 5×5 or 5×6. Here is a problem, how to meet these requirements? Our considerations are also based on the current general requirements of 70% or 80%. There are two important conditions here. One is the industry standard. In addition to the 3GPP card, there are also requirements for the semiconductor industry, as well as the requirements related to the automotive industry. There have been many visits here.
At present, there is no complete standard for industrial-grade SIM cards in the world, and there is no 3GPP specification for ordinary SIM cards. We have done a lot of work here. In addition, the current card needs to consider its production capacity. It must be combined with the current chip manufacturers, distributors, material manufacturers, and card manufacturers. What are their production capacities? There are card production requirements. There are related requirements for the module, here more combined with the needs of the industry. Of course, the technology considered here is not only the requirements of physical characteristics, such as the sub-assembly process, packaging materials will have requirements. There is also a product form, this is also very important. If it is not fixed, there will be many kinds of China Mobile SIM cards. The operating cost is very high, and it has many adverse effects on the industry chain. At the same time, SIM cards have different needs in the IoT environment, such as the requirements of interfaces and communication requirements. So far, the application of the Internet of Things SIM card has not been very strong. I think more of these features will be developed in the future. In addition, the changes made in the issuance of cards. For example, if this card has a number after China Mobile bought this card, it will be available only when it is actually used. If it is used, this number will be used. How to write this number and how to activate it. In fact, China Mobile also tried to issue cards in the air in 2005, but in the IoT environment, in many cases, it is impossible for people in the business hall to go to various places to do card-issuing work in the mountains and in the ocean. It is necessary to issue a card for China Mobile's network, and there are many problems in front of the car. In fact, we also raised it at the 3GPP conference, which is related requirements. For European and American operators, there is still no strong demand.
In fact, for the industrial chain in the IoT environment, the SIM card includes requirements for chips, cards, and modules. The requirements for the chip, through the previous indicators, are reflected in many aspects, on the one hand, its processing speed, chip processing speed from the original eight to sixteen, thirty-two, and then the interface type; Power consumption, sleep mechanism, low-cost requirements, power consumption is relatively lower, including the original industry, the original .18 or .13 process level, up to the capacity level of 92 nm, 65 nm And so on have related influences and requirements.
In the Internet of Things communication, the requirements for terminal communication in human-to-human communication are different. Human-to-human communication, terminal requirements are larger screens, better video processing, including large amounts of storage. However, in the case of the Internet of Things, the requirements for the machine, the requirements for the items, and the requirements of the communication module are miniaturization, low power consumption, and low cost. In this case, the SIM card will play a bigger role. For example, a basic feature of the SIM card, one is to do identity and the other is to do security services. Identity is the soundness of the network, and it can also do a lot of application data robustness, or it is an item identification. From the perspective of security services, it can store some information securely, information between objects, or more confidential information can be stored in the SIM card. At the same time, the SIM card has its own ability to authenticate and solve. In the whole Internet comprehensive perception and information processing, as well as intelligent processing and information transmission, the security guarantee for information transmission can play a certain role in the SIM card. This is the aspect of the SIM card capability. At the same time, there are two important functions that can be played on the interface of the SIM card. On the one hand, it is an ordinary module, and the interface between the wireless modules. This interface is very similar to the normal interface, can be delivered, can also use the mobile Internet for data transmission, improve transmission rate and related capabilities, in addition to the ability to perceive. This aspect is also in the stage of exploration, such as the ability to put RFID antennas in the SIM card and the related Bluetooth, which are technically feasible. In fact, as long as we think about it, we can do more things on the SIM card for comprehensive perception. When the underlying capabilities and identity capabilities are all available, the upper layers will assist in more applications.
In general, the trend of SIM card development can make the mobile communication industry more secure, more efficient and smarter in the IoT environment.
