Nowadays, countries are vigorously developing NB-IoT. NB-IoT is the commercial start-up year in 2017, and 2018 may be the outbreak year. NB-IoT is an emerging technology in the IoT field and a catalyst for the Internet of Things. What is he? Charisma attracts so many people crazy about it.
Today, the country attaches great importance to the Internet of Things, and the Internet of Everything has become the vision of all relevant industry people, but at the same time, mastering the standards of the Internet of Things is the weapon to control the future voice of the Internet of Things.
The origin of NB-IoTFor the development of the Internet of Things standards, Huawei's advancement was the earliest. In May 2014, Huawei proposed the narrowband technology NB M2M. In May 2015, NB OFDMA was formed by NB OFDMA. In July, NB-LTE and NB-CIOT were further integrated to form NB-IOT.
In September 2015, the global communications industry reached a consensus on the formation of a low-power, wide-area coverage (LPWA) IoT standard, and the NB-IoT standard came into being.
In June 2016, 3GPP announced the completion of the NB-IoT designation work. The end of the NB-IoT standardization work also means that the core protocol for the physical network in Release 13 has been completed. Recently, as NB-IoT crosses the standardization threshold and officially enters the commercial stage, the industry's attention and discussion on it has gradually warmed up.
NB-IoT refers to the Narrow Band Internet of Things, which is an important branch of the Internet of Everything. NB-IoT is an emerging technology in the IoT space that supports low-power devices in the WAN cellular data connection, also known as low-power wide area network (LPWAN).
Countries vigorously develop NB-IoTDue to the many advantages of NB-IoT, operators inside and outside the world have realized the future blue ocean of the Internet of Things and increased the layout of NB-IoT. KT plans to invest 150 billion won to build a new NB-IoT network; Vodafone accelerates the deployment of the Internet of Things and establishes the NB-IoT Open Lab, which will examine network solution validation, new application innovation, device integration, business model research and product qualification verification. EtcoMo will develop the M2M business as an important component of its ubiquitous network strategy, and promote the development of the M2M market by establishing platforms and embedded modules; Sprint promotes the M2M market through an open development strategy.
In 2017, China's basic telecommunications companies vigorously promoted the construction of NB-IoT networks, and built more than 400,000 NB-IoT base stations throughout the year, achieving coverage for major cities such as municipalities and provincial capitals. Among them, China Telecom took the lead in building the world's first fully covered NB-IoT network, with more than 310,000 NB-IoT base stations at 800MHz.
However, although NB-IoT has been successfully commercialized and the fields involved in the application are very extensive, the applications that have achieved a certain scale of development are rare, mainly concentrated in a limited number of fields such as meter reading business and parking service.
Advantages of NB-IoTWhy NB-IoT is so concerned, and its remarkable features are inseparable. The first is coverage. NB-IoT improves coverage by mainly improving power spectral density, transmission repetition and uplink Inter-site CoMP.
Secondly, the capacity, the low rate requirement of the IoT service and the insensitivity to delay determine the characteristics of NB-IoT with Xiaobao data transmission and terminal extremely low activation currency. Moreover, NB-IoT greatly improves the spectrum efficiency by reducing the air interface signaling overhead. According to the evaluation of related equipment manufacturers, NB-IoT will increase the uplink capacity of mobile networks by 50~100 times, and can provide up to 100 times the access number of existing wireless technologies.
Thirdly, 3GPP introduced the power saving mode (PSM) and eDRX technology in the related series of standards, and NB-IoT truly has low power consumption characteristics. The NB-IoT target is for a typical low-rate, low-frequency sub-business model, with a capacity battery life of more than 10 years. According to the simulation data of 3GPP TR45.820, PSM and eDRX are deployed in a harsh environment with a coupling loss of 164 dB. If the terminal sends 200 B messages once a day, the battery life can reach 12.8 years at 5 Wh.
Finally, at the cost, the NB-IoT terminal chip can be as low as $1. The terminal chip is usually composed of a processing module, a radio frequency module, a power amplifier module, a power management module, and a flash/RAM. Compared with 4G smartphones or other terminals, NB-IoT terminals use narrowband bandwidth of 180 kHz, and baseband modules have low complexity; low data rate and protocol stack simplification can greatly reduce the size of Flash/RAM; single antenna, half-double The way of working can effectively simplify the RF module.
Tilt policy promotes NB-IoT developmentNB-IoT, which has many advantages, is naturally favored by all parties. The industry judges that in 2018, the ecological environment of NB-IoT will be under the joint empowerment of the government, operations, equipment, chips, modules and other industries. more perfect.
In 2017, the Ministry of Industry and Information Technology issued the "Notice on Comprehensively Advancing the Construction and Development of Mobile Internet of Things (NB-IoT)", "Announcement on Frequency Use Requirements of NB-IoT System", and subsequently issued the IoT dedicated number segment to the three basic telecommunications companies. Support NB-IoT to build a complete industrial system and ecosystem.
Under the guidance of the Ministry of Industry and Information Technology, the NB-IoT Industry Alliance, jointly established by China Telecom, China Mobile, China Telecom, China Unicom, Huawei, ZTE, Baidu, Ali, Tencent, etc., has entered a benign operation.
The favorable rules will naturally lead to the rapid expansion of the market scale. Relevant institutions predict that the shipment of NB-IoT will exceed 100 million in 2018, which is also a huge stimulus for the market. At present, NB-IoT can be said to be highly regarded. Today, China's NB-IoT network has accounted for 90% of the world, and industry development has entered the global ranks.
summaryNB-IoT can be said to be a commercial start-up year in 2017, then in 2018, NB-IoT will be a year of scale, the bigger the market, the greater the value. The Ministry of Industry and Information Technology predicts that the number of NB-IoT base stations in China will reach 1.5 million in 2020, and the M2M connection based on NB-IoT will exceed 600 million.
The landing of NB-IoT will also speed up the development of the Internet of Things and lay a solid foundation for the Internet of Everything.
