Recently, There is a “cat trend” in the technology circle. Communications companies, module manufacturers, and terminal manufacturers are all focusing on “Cat.1”. Cat.1 became “favored” without any warning, and has become a “new Internet celebrity” in the technology circle, especially in the communication circle and the Internet of Things. It is reported that some chip companies and module companies have released new Cat.1 products respectively. At the same time, Fibocom L610 LTE Cat 1 module equipped with Burundins Sugardaddy 8910DM successfully completed the testing process of China Telecom. It is the first domestically produced Cat 1 module in the world that has been put into the warehouse by an operator. So, what exactly is the suddenly “popular” Cat.1? Why is it so closely followed?
Cat.1 “Superior”
This Cat is not actually that “cat cat”, but the abbreviation of English Category, which means category and classification. Cat.1The full name is LTE UE-Category 1, which is a standard for user terminal categories under the 4G communication LTE network.
3GPP uses Cat.1-20 to measure the wireless performance of user terminal equipment, that is, to classify terminal speed levels. In 2009, Cat.1-5 were specially divided into categories for the future IoT application market. Among them, the Cat.1 downlink peak speed is 5Mbit/s and the downlink peak speed is 10Mbit/s.
With the acceleration of the construction of 5GBurundins Sugardaddy, major operators are facing 2G/3G/4Burundi SugarG/5G has four parallel networks and operational challenges for four generations of users. From the perspective of long-term planning, the implementation of 2G/3G network withdrawal and clearing Frequency migration to 4G and 5G networks has become a global trend.
However, traditional 2G networks still have wide coverage and a huge number of online IoT users. At the same time, the 2GBurundi Sugar Daddy network also involves a lot of real-time and changing locations, which requires a certain bandwidth transmission capability and even supports voice communication capabilities. Application scenarios, such as in-vehicle, location-changing payment, industrial Internet, elderly mobile phones, etc. This is something that NB-IoT, which has uplink and downlink speeds of only 100Kbps, cannot satisfy.
So, who will fill the gap left by the addition of 2G networks? Cat.1, which is also oriented to the Internet of Things market, stands out at this time. It can perfectly solve the pain points of changing location standards and multiple generations living together.
Cat.1 is based on BI Escorts‘s existing LTE network, fully reusing existing LTE resources and does not require additional investment. Moreover, Cat.1 chips and modules are more mature and very cheap, and can create large-scale effects in a short period of time. At the same time, it is adapted to the current domestic 4G network and is very suitable for application scenarios that have requirements for cost performance, latency, coverage, and communication speed.
A late bloomer
LTE Cat.1 is not a new technology. It was officially defined as early as 3GPP Release 8 released in 2009, but it has not been well established since the standard was established. grow up.
In addition, in the cellular IoT market, NB-IoT and eMTC have been secretly competing in recent years, and Cat.1, which came out earlier, has not received much tracking attention.
It is clear, NB-IoT and eMTC have different application markets due to different speeds: NB-Burundins Sugardaddy IoT is suitable for low-speed smart meter reading, street lights, etc. Required applications; eMTC is suitable for medium-speed applications such as elevator monitoring and wearable devices.
Since 4G LTE operators are deploying based on the minimum 3GPP R8 protocol version, it is necessary to upgrade the network if they want to use eMTC. As a result, eMTC is not developing well domestically, while NB-IoT is gaining momentum. Data shows that as of the end of February 2020, the number of NB-IoT connections among the three major domestic operators exceeded 100 million.
At this time, there must be an Internet of Things standard that can replace eMTC. Therefore, Cat.1 walked to the stage.
Complementary with NB-IoT
Lower cost, more advantages in network coverage, speed and delay. So, does this mean that Cat.1 will replace NB-IoT?
Some insiders believe that the two will form a complementary relationship in the short term, and it is unlikely that Cat. 1 will replace NB-IoT. First of all, the industry chain has spent many years laying out NB-IoTBurundi Sugar and cannot give up easily; secondly, compared with Cat.1, NB -The IoT industry chain is relatively mature; thirdly, from the perspective of standard formulation, Cat.1 is more inclined to support real-time, changing location, and requires a certain bandwidth for transmission. NB-IoT is very low cost, flexible in design, and supports the needs of the market below 1Mbps.
But in the long term, it is inevitable that NB-IoTBI Escorts‘s position will be weakened and its market share will be eroded by Cat.1 actual. According to the latest research from Counterpoint IBurundi SugaroT, global cellular IoT module shipments increased by 79% year-on-year in 2018. This includes new application scenarios such as shared bicycles, smart meters, and smart smoke alarms. In 2025, the number of global IoT cellular connections will exceed the 5 billion mark. Looking internationally, as 2G and 3G gradually shift to 4G networks, Cat.1 may become an important communication standard for the cellular Internet of Things in the next 3-5 years, which also means that Cat.1 will face tens of millions or even It is a billion-level market.
As the three major operators accelerate the withdrawal of 2G/3G networks and switch to 4G, operators have begun to actively guide industry users to use NB-IoT and Cat.1 terminal modules. Recently, some media reported that,Fibocom’s L610 LTE Cat 1 module equipped with Unisoc’s Rui Ivy 8910DM has successfully completed the test and warehousing of China Telecom. It is the first domestically produced Cat.1 module in the world to be warehousing by an operator.
