What is Cat.1 What is the difference between the application scenarios of Cat.1 and Cat4

Cat.1 is a standard for user terminal categories under the 4G communication LTE network.

As the carrying capacity of the 2G network further weakens, NB-IoT and 4G will gradually replace 2G modules in newly deployed IoT connections. Compared with NB-IoT, Cat.1 has advantages in network coverage, speed and delay; compared with traditional LTE Cat.4 modules, it has the advantages of low cost and low power consumption.

Comparison of Cat.1 and Cat.4

1. Cat.1 has more cost advantages: For example, in terms of network construction, LTE Cat.1 can now be seamlessly connected to the existing LTE network without upgrading the software and hardware of the base station, and the cost of network coverage is very low. In terms of chip cost, after system optimization, the integration level is higher, the hardware structure of the module is simpler, and the cost of peripheral hardware is lower.  

2. Compared with Cat.4, Cat.1 has the same advantages in terms of speed, delay and mobility. It has the same millisecond-level transmission delay as LTE Cat.4, and supports a moving speed of more than 100KM/H.  

3. Cat.1 has more application advantages: Since Cat.1 belongs to the 4G series, it can completely reuse the existing 4G resources. Cat.4 is migrated to Cat.1, and the benefits are obvious. For example, in scenarios where 4G is used for voice interaction such as walkie-talkies and toy robots, Cat.4 can be switched to Cat.1 before. In many voice function and medium-rate connection scenarios, Cat.1 will play a role. These scenarios include sharing, financial payment, industrial control, vehicle payment, public network intercom, pos, etc.

Cat.1 application scenarios: wearable devices, smart home appliances, industrial sensors, hydrology and water conservancy detection, and port logistics tracking. Shared payment class. The requirements for broadband speed are not high, and at the same time, it is battery-powered. The requirements for power consumption and data transmission stability are very high.

Cat4 application scenarios: Internet of Vehicles, smart grid, 4G wireless routing, video security, commercial display equipment, 4G law enforcement devices. Live video equipment. etc. have very high requirements for broadband speed. At the same time, the requirements for stability are higher.
