In an instant we have entered 2018. In the past few years, especially in 2017, the development and application of Internet of Things technology has undergone rapid changes. In addition to telecom operators represented by telecommunications and enterprises represented by Huawei, as always, they have strongly promoted NB-IOT. Mobile and China Unicom have also begun to aggressively intervene. Compared to 4G technology and even 5G technologies in the near future, NB-IoT has great advantages in terms of the number of connections, signal coverage depth, power consumption, etc., and the official effect brought by the Ministry of Industry and Information Technology, NB-IoT The development space and the imagination space are much larger. It can even be a revolutionary technology as a whole. As the only three players in the field of operators, naturally no one wants to let go of this piece of cake. Especially after experiencing China Mobile's thriving development in the 4G era, in the face of this new enthusiasm, the three companies have launched fierce competition in areas such as infrastructure construction, ecological construction, application development, and tariff competition, mainly in the following aspects: : 1. Infrastructure China Telecom used the 800M LTE network to build the world's most extensive NB-IoT network in 2017. The total number of base stations has reached an astonishing 310,000, which means that it can achieve full coverage in most parts of the country. China Mobile has also completed the deployment and construction of the first batch of 146,000 NB-IoT base stations. In particular, in June 2017, the Ministry of Industry and Information Technology issued an announcement stating that, in the allocated GSM or FDD IMT system band, operators can select the inband working mode, the protection band working mode, and the independent working mode to deploy the NB-IoT system as required. . This is a huge positive news for China Mobile, which has not obtained an FDD license. Because of the abundant GSM900 band, it can be predicted that the speed of China Mobile's NB-IoT construction in 2018 will reach a new stage. China Unicom is not to be outdone. Although it is a bit late compared to mobile and telecommunications, it has already deployed commercial NB-IoT solutions in major cities and has more than 300 cities have fast access to NB-IoT networks. Ability. At the same time, China Unicom has also opened the eMTC trial network in various regions such as Beijing and Guangdong, with trial commercial conditions. 2. Ecological construction China Mobile took the lead in launching the China Mobile IoT open platform on its official website. In addition to detailed development documents and strong community-based discussions, the technical discussion on China Mobile is also very enthusiastic on some well-known EE forums. China Mobile, which uses its own development strategy, provides more than 30 proprietary web APIs for use by customers and developers on the connection management platform. China Telecom established an Internet of Things branch as early as 2009. In the open platform of China Telecom’s Internet of things, B2B2C business, real-time monitoring, direct integration with business systems, data services and cost management have become important for attracting developers. factor. While China Unicom is moving toward internationalization, it has also launched a new generation of connection management platforms. With more powerful data analysis and automation capabilities, more reliable security protection measures, and more flexible partner business operations capabilities as selling points, although not dominant in the frequency band resources, it is also used to make up for its ecological construction. 3, partners As the oldest brother in the 4G era, China Mobile is naturally cultivating thousands of pets in the era of NB-IoT. It is not only a solution partner of Xingyuan Instrument and West Grain, but also a SaaS partner such as Neusoft and iSoftStone. There are hardware terminal partners such as Qualcomm, Hass, RDA, etc., combined with mobile's consistently good working style, big and complete development plans are also reasonable. And China Unicom and German Telecom, Hong Kong Telecom, Bell Canada, Dutch Telecom, Taiwan Mobile and other operators close cooperation, the goal of the global IoT service market, can be described as an alternative. Of course, China Unicom and Cisco, Lenovo, Qualcomm and other hardware giants also have a strategic cooperative relationship, it seems that China Unicom in this NB-IoT war situation is still not small. And China Telecom naturally stood on the same front with Huawei, the domestic NB-IoT leader. On this basis, the concept of “Great integration of products, large linkage of channels, and sharing of results†is also a plus for telecommunications. 4, tariff competition In terms of tariffs, we must mention that China Telecom, which claims to have only RMB 105 for 8 years, has attracted many people's attention. In the context of speeding up and fee reduction in the traditional communications market, together with the emerging NB-IoT technology itself has the advantage of low cost, so China Mobile is carrying out special subsidies and special promotions. Although China Unicom has not released any specific information, the concept of domestic and international access through connection points rather than traffic charges should not change. 5, application areas In fact, the Internet of Things is also good, NB-IoT worth mentioning, in the final analysis, the greatest value is still in the "Internet of Things" to change our lives, so that the landing of various solutions is the NB-IoT the greatest value lies, but also the three major The operator's core competitiveness and long-term development potential lies. In the development of China Mobile in recent years, it has been involved in smart water meters, gas meters, smart agriculture, and animal husbandry and fishery production monitoring. Among them, vehicle information monitoring and remote management systems have been highlighted. After all, as we all know, automotive electronics is a sub-sector in all electronic fields, but at the same time it is an area with huge potential for development. The reason why the Internet of Things is so good is due in large part to the enormous potential of car networking. And prospects. China Telecom has outstanding performance in public utilities, smart logistics, smart homes, smart retail, medical and health care. Among them, the latter two are more promising by countless practitioners. Since Alibaba introduced the concept of new retail, it has caused a reign in the retail market, and everyone has greater expectations for the combination and collision of the Internet of Things and new retail. In the medical and health field, the market has always been huge. To say the least, if telecommunications can eat medical wisdom, this big cake is enough to be invincible. On the other hand, China Unicom's first pilot in Shanghai was smart firefighting. Afterwards, it dived deeper into areas such as smart water, smart parking, smart homes, and smart wear. It also did not fall behind in development. The global Internet of Things is developing rapidly. China, as a rising power, naturally does not want to miss this wave of technology. Mobile, telecommunications, and Unicom are all competitors, but all of them have demonstrated the development of NB-IoT technology. Strong determination, appropriate Hardening Accelerating Admixture Accelerators are used to increase the initial rate and speed of the chemical reaction between cement and the mixing water. Hardening accelerating admixture are used to reduce demoulding time or to speed access onto concrete floors and pavements and by this speed up the construction process.

Accelerating admixtures can be used to increase either the rate of stiffening or setting of the concrete or the rate of hardening and early strength gain to allow earlier formwork striking and demoulding. Most accelerators achieve one rather than both of these functions.
Hardening accelerators are most effective at low temperature. Accelerators can be used with superplasticisers where early age strength is required, especially at lower temperatures.
