 5g narrowband iot

In 2020, the number of global IoT connections will exceed the number of non-IoT 5g narrowband iotconnections for the first time, and the IoT will grow rapidly again after achieving "value for money". This year, the "first quarter of 2022 communication industry economic operation" shows that the number of IoT connections exceeds the number of human connections, the "superhero of things" era is coming, the Internet of things is driving to the fast lane.

"2G, 3G era, IoT is NB-loT narrowband IoT, only 20/250kbps data rate, 4G era is medium-speed IoT, is on the 5 / 10Mbps data rate, to the 5G era, IoT technology development for large bandwidth IoT, large connection and networking, medium-speed low latency IoT, passive IoT, etc., data rate, connection number density have been significantly improved to enhance." Chinese National Academy of Engineering research expert system recently at the Best Things Conference clearly stated.

According to experts, the so-called broadband IoT, 5G single carrier bandwidth of 100MHz, downlink peak Gbps in the Sub6GHz band. But 5G uplink peak in 100MHz u002F3.5GHz only 350Mbps, because TDD mainstream time slot ratio is 7D3U. And industrial applications need big uplink, can be through uplink carrier aggregation CA (high and low frequency band simultaneous carrier), uplink decoupling SUL (plus low frequency complementary uplink), super uplink (TDD and FDD synergy, high and low frequency complementary, time-frequency domain aggregation, 20% increase in bandwidth and 30% reduction in latency).

5g IoT is mainly used for bike sharing, autonomous driving, environmental monitoring and other applications. In 5g, the new bandwidth slicing feature, 100mhz carrier can be divided into supporting large connections while narrowband IoT, and also embb and urllc frequency networks. In addition, for IoT, 5g iab (access and return integration) technology can also be accessed - using the same frequency and air resources to provide access and return capabilities to support d2d applications, using cloud-based brains to manage large numbers of robots, AGVs and drones working collaboratively via 5g with low latency and low cost.

5G IoT, also known as 5G Optical New AirPort (NR-Light) and 5G RedCap, provides 50u002F100Mbps upstream and downstream rates in 10 to 20MHz bandwidth with 5 ~ 10 ms latency and cost is expected to be 60 ~ 70% lower than 5G modules to support industrial sensors, surveillance cameras, wearable devices, medical monitoring devices and other networking applications.

In addition to our just IoT technology application capabilities, will also face FMCG, logistics for parcels, product overwrap, warehouse management goods inventory and smart water meters and other massive information physical learning terminals as many as one hundred billion pieces per year, but due to the student's own development conditions and cost control restrictions do not have a small battery system power supply, can not meet the use of NB-IoT. in addition, RFID also has some Problem defects, due to RFID energy and transmitting and receiving data signals are from a dedicated reader, resulting in sending and receiving since the interference, transmission security distance is short, the amount of stored data is small, no NFC difficult to interact with the cell phone network, and they can not be used in their own possession of a very dense terminal scenario, which is when the 5G passive Internet of things came into being.

Experts say that 5G passive IoT is driven by base station signals, but because each 5G-shaped beam moves continuously in a narrow direction, it is difficult to accurately collect the energy of 5G beams, so Rotman lenses can be used to collect and converge multi-beam energy simultaneously, and metal-semiconductor-metal MSM diodes with high responsiveness can be used to improve energy conversion efficiency. Meanwhile, the evolution of 5G standardization has enabled low cost, wide coverage and scale through simplified RF, DSP, protocol stacks, synchronization, coverage enhancement techniques and new interference management techniques.

In addition, the combination of technologies such as 5g and wifi + lot can be extended to more industries and domains. For example, remote control of tower crane operation, Tianjin Qingdao port is a good example, set up 30 cameras on the Quaybridge rail crane (data transmission rate of 30mbps), through wifi convergence to 5gcpe, about gigabit transmission to the control center, work efficiency increased by nearly 20%, single box energy consumption reduced by 20%, reducing more than 60% The work efficiency is improved by nearly 20%, the energy consumption of a single box is reduced by 20%, and the overall operation cost is reduced by more than 60%. Taking the 5 g smart coal mine as an example, Sun Yuan coal mine cooperated with China Mobile and Huawei to install 30 ~ 404k cameras on the 240m roadway of the mine's comprehensive mining face. The cameras are connected via wifi and transmitted via gigabit to 5g cpe, as well as remote control of underground excavators, etc.

Further, IoT can be combined with cloud computing and artificial intelligence. In terms of 5G smart network, experts and academicians introduced that the data collected by IoT in the past was transmitted to cloud computing and artificial intelligence through communication network. However, due to the lack of communication network bandwidth and large time delay, artificial intelligence decisions cannot be fed back to the IoT level for execution in the first place, while the high bandwidth and low time delay of 5G opens up the whole process from data collection to decision making, seamlessly integrating IoT with cloud computing and artificial intelligence. At the same time, AI chips and operating systems can be directly embedded in 5G IoT modules to form AIoT terminals.

In addition, experts have analyzed and explained the 5G IoT network. "5G IoT network increases the P2P capability of IoT network relative to the general IoT development of enterprises, and also increases the support technology capability of IoT, which can be used as support for applications related to blockchain. Through the study of blockchain from the Internet to understand to the cloud to the chain, from the Internet of things to the Internet of wisdom to the Internet of letters, from the interconnection between everything to the Internet of wisdom to the Internet of letters." For example, home network cameras, intelligent control of street lights and other IoT terminal devices are easy to be hijacked at the same time and become a springboard for DDoS, and need to be upgraded IoT gateways to enable timely detection and prohibition of hijacked IoT terminal users to access management targets as well as servers, while the security of multiple IoT gateway systems themselves can only be guaranteed mainly through a blockchain connection established.

In terms of 5G AIoT endpoints, the 5G Industrial Module includes the 5G IoT Module/Customer Front End Equipment (CPE), a device used to relay 5G signals from base stations and multiplex connections. It provides computing support and intelligent mobile routing device functionality and is open to third-party programming. The 5G Industrial Gateway adds PLC, edge computing, smart network, blockchain, IPv6, TSN and other industrial control device functions to the 5G industrial module to promote the integration of IT and production technology (OT). Realize flat and intelligent enterprise network.

" ipv6 is also a good way to help 5g IoT. 5g + ipv6 provides ipv6 multi-homing capabilities: multiple ipv6 prefixes can be assigned to a single pdu session at the endpoint; source address-based mobile edge computing traffic classification applications can target different quality of service service offerings; and 5g switching can provide built-in and disrupted business continuity. In addition, edge computing will be widely used in 5g IoT. In the future, mobile base station pass-through sensing will support the development of IoT."

In the expert's view, 5G IoT is not just a way to connect IoT, but some endogenous features of 5G also empower the upgrade of IoT.

Specifically, one is that 5G opens up new areas of IoT to mobile, broadband, large connectivity and low latency applications. Second, 5G's default data adoption of IPv6 and built-in network information security management capabilities development and combination with MEC (computing at the edge) provide technology support for latency and reliability sensitive IoT system applications. Third, 5G + IPv6 + MEC will strengthen the security of the IoT and help students to solve the problem of relatively weak ability of IoT terminals to work on the security risk defense of the network environment. Fourth, 5G IoT aspect has the characteristics of cloud-network edge-end integration, around 5G + edge cloud platform can polymer can networking company products and applications, can solve the problem of China's traditional IoT-related products of different types more difficult to achieve scale and IoT as a small and scattered enterprises difficult to become a cluster.
