Why did Cat1 become popular when these sub-scenarios were "drafted" in IoT technology?

In the era of the Internet of Everything, the premise of all innovations based on the Internet of Things is "connection", and different application scenarios require different connection technologies. With the alternation of new and old technologies, industry user needs and scenes are becoming more segmented, a medium-rate market between high-rate and low-rate scenes is booming.

 Faced with the special needs of some special industries with medium and low speeds, ultra-stable connections, and low costs, how to choose a suitable connection technology from multi-dimensional considerations such as speed, cost, network coverage, and technological maturity? It has become a question that the IoT industry needs to think about.

Research data shows that in the distribution of cellular IoT connections, 60% of scenarios require narrowband networks to provide "low rate" connections, about 10% of scenarios require "high rate" connection services, and the remaining 30% of IoT scenarios require "Medium rate" connection service.

At present, the cellular network connection technology is in the window period of the replacement of the old and the new. On October 22, 2019, Wen Ku, Director of the Information and Communication Development Department of the Ministry of Industry and Information Technology made it clear: The withdrawal of 2G and 3G is an inevitable choice for the upgrading of mobile communications, and it is also the main practice of various countries in the world. At present, the conditions for the withdrawal of China's mobile communication network 2G and 3G have gradually matured. It is foreseeable that after the 2G/3G withdrawal in the future, the remaining several cellular network connection technologies will perform their duties in various scenarios of the Internet of Things.

IoT technology based on 4G/5G (NB-IoT+4G+5GNR) will gradually replace the original 2G/3G IoT technology, and provide greater bandwidth, lower latency, and deeper coverage, truly opening up thousands of industries The era of interconnection-5G will take on high-speed scenarios with large bandwidth and extremely demanding delay requirements.

NB-IoT will meet the needs of large-scale narrowband and low-rate scenarios with features such as wide coverage, low power consumption, low cost, and large connections, and will be used in small data volume and low-rate scenarios such as smart meter reading.

With the withdrawal of 3G networks in the future, 4G LTE and eMTC will be able to carry voice and medium-rate scenarios. However, because domestic operators are not active in eMTC, and the eMTC industry chain is not open and robust enough, eMTC will be available in China in the short term. It is difficult to achieve network construction, so 4G LTE will assume the important task of rate connection scenarios in the Internet of Things.

According to the latest research data from Counterpoint Research, a market research organization, the global IoT cellular connections are expected to exceed the 5 billion mark by 2025, and China will continue to lead the world with nearly two-thirds of the number of connections. 4G LTE IoT connections will account for more than one-third of global IoT cellular connections.

However, although 4G LTE will play an important role in cellular IoT connections, even in medium-rate scenarios, the needs of different sub-industries are different.

Especially public network intercom, sharing economy, financial payment, wearable/tracking, smart energy, industrial control, etc., have high requirements for module cost, power consumption, communication delay and other capabilities, but are not very sensitive to speed. Industry applications also require connection technologies that are more suitable for these specific scenarios.

Broadly speaking, the rate scenarios in the Internet of Things connected by LTE can be supported by Cat 1 and Cat 4. Although LTE Cat 4 supports higher rates and low latency and has excellent network coverage, it is not suitable for the aforementioned rate requirements For industry applications that are not high, but are more sensitive to delay and cost, the opportunity for LTE Cat.1 is here.

It is understood that Category is the abbreviation of Category, that is, classification, category, 3GPP uses Category 1-20 to measure the wireless performance of user terminal equipment, that is, to divide the terminal rate level. According to the 3GPP Release definition, UE-Category is divided into 10 levels from 1 to 10, Cat 1-5 is in the R8 group, Cat 6-8 is in the R10 group, and Cat 9-10 is in the R11 group.

In summary, Cat 1 has the following three advantages if it is applied to IoT scenarios that simultaneously require a certain speed (mainly low and medium speeds), meet certain high-speed mobile requirements, and support voice.

Advantage 1: Global coverage, mature network. The 4G network that has been in commercial use for many years has basically achieved global coverage, fully covering major operator network frequency bands in Asia, Europe, America and other regions. Cat 1 can also provide Internet of Things users with access anytime, anywhere with the help of 4G network infrastructure construction.

Since 4G LTE operators around the world are deployed based on the lowest 3GPP Release 8 protocol version, operators do not need to upgrade the network, and only need to configure simple parameters to allow Cat 1 terminals to access the network. In China, as of the end of 2019, the total number of 4G base stations in my country has reached 5.44 million. Advantage 2: Better network and more functions. Compared with NB-IoT in terms of voice, short message, connection timeliness, cell handover, etc., the maximum downlink rate supported by Cat 1 is 10Mbps, and the uplink rate is 5Mbps, which can achieve higher performance connections and less than 100ms. Low latency. Advantage 3: Lower cost and high cost performance. Although the Cat 4 rate of up to 50Mbps in the uplink and 150Mbps in the downlink is higher, the current mainstream Cat 4 is difficult to meet the IoT application needs of some industries in terms of power consumption, integration, and price, while Cat 1 takes into account the standard, performance, and power consumption. , Cost and other advantages, especially the cost is nearly 30% lower than that of Cat 4.
