There are several important technical drivers for the substantial growth of the number of object-to-object connections: on the one hand, a large number of devices based on LTE cat. 1 are emerging, which in fact drives the rapid popularization of the sharing economy; On the other hand, zhanrui expects that from around 2023 / 2024, devices supporting the redcap feature of 5g R17 technical specification will become popular. It will further provide ultra-high-density connection capacity and truly “connect every stone to the Internet”.

With a large number of Internet of things connections and intelligent computing superimposed on the upper end, edge and cloud, the boundary between the digital world and the physical world will be broken, and the digital dividend will also be extended from the consumption field to various basic industries of society.

5g: change connection mode and expand connection scenario

The innovation of mobile communication in the past dynasties is represented by significant technical characteristics and typical application scenarios. Before the emergence of 5g, mobile communication mainly focused on communication between people, supporting rich consumer services. 4G changes life and 5g changes society. 5g defines inter object communication as the main scenario and promotes the outbreak of animal networking industry. In the 5g era, people want to build an intelligent world that is fully connected between people, people and things, and things and things.

At present, the cellular communication network presents the situation of four generations living together. It is the general trend to accelerate the network transfer from 2G / 3G to 4G / 5G. Communication standards for IOT scenarios began to appear in the 4G era, such as NB IOT low-power wide area IOT, cat. 1 medium speed wide area IOT, etc; However, most of these standards have evolved gradually on the basis of human networking. 5g is the first communication system born for the Internet of things: 5g has three scenarios: embB pursues the ultimate large broadband mobile communication experience, which is the first commercial one in the three scenarios of 5g; Urllc provides extremely low delay and high reliability, which is the key killer of 5g industry-oriented connection applications; Mmtc builds the interconnection of all things.

5g R16 ready: make 5g from “usable” to “easy to use”

5g R15 standard is mainly aimed at embB scenarios. Firstly, 5g basic functions are realized to ensure 5g “availability”; R16 standard improves the characteristics of urllc and mmtc, makes 5g from “usable” to “easy to use”, accelerates the large-scale application of 5g in industries such as industry, automobile, energy, medical treatment and public utilities, and makes 5g an important starting point for promoting the digital transformation of economy and society.

5g R16 is enhanced on ultra-low network delay and highly reliable network: it supports 1 microsecond synchronization accuracy, 1 millisecond air interface delay, reliability of 99.999%, flexible terminal group management, end-to-end delay within 5 milliseconds and higher reliability at the fastest, supports industrial time sensitivity, and greatly reduces power consumption. In one sentence: R16 is faster, more reliable, more accurate and better used, and can better support the needs of 5g + industrial Internet.

In July this year, zhanrui and China Unicom successfully completed the end-to-end service verification of the world’s first embB + urllc + iiot (enhanced mobile broadband + ultra-high reliability and ultra-low delay communication + industrial Internet of things) based on 3GPP R16 standard. From the measured results of the world’s first 5g R16 ready technology verification displayed by zhanrui, it can be seen that 5g R16 high-precision timing can improve the time synchronization accuracy to the order of hundreds of nanoseconds.

Through high-precision timing, the coordination and cooperation between different industrial equipment can be accurately synchronized and achieve accurate connection and interaction. Another typical application scenario of high-precision timing is smart grid, which can realize the transmission of power differential protection service signal, quickly judge and accurately locate distribution faults, and quickly isolate faults. Last year, based on 5g R15 existing network environment, zhanrui has verified microsecond high-precision timing with partners, reducing the power supply recovery time from minute level to second level. This year, based on zhanrui 5g R16 ready platform v516, zhanrui successfully increased the clock synchronization time by another order of magnitude, which is expected to further shorten the fault isolation time and realize zero perception of power failure.
