What is Cat.1?

The full name of Cat.1 is LTEUE-Category1, where UE refers to User Equipment, which is a categorization of the wireless performance of user terminal equipment under LTE network. According to the definition of 3GPP, UE category is divided into 15 classes from 1 to 15. The ultimate goal of Cat.1 is to serve the IoT and realize the purpose of low-power and low-cost LTE connectivity,lte cat 4 which is of great significance for the development of IoT.

What is 4G?

4G refers to the fourth generation of mobile communication technology, including TD-LTE and FDD-LTE. it is a better improvement of 3G technology. It has more advantages compared to 3G communication technology. It is the perfect combination of WLAN technology and 3G communication technology, which can make the image transmission faster.lte cat1 It makes the quality of the transmitted images and the images look clearer.The application of 4G communication technology in smart communication devices makes the internet faster for the users and the speed can be up to 100Mbps.

Difference between Cat.1 and 4G

Cat.1 belongs to the 4G family and can fully reuse existing 4G resources. Although the 4g module mainly uses Cat.4, and the download rate can reach 150m, most IoT scenarios do not require such a high rate. With the development of the mature 4G industry chain, Cat.1, as the low-end version of 4G, can be quickly brought to market with only a few changes to existing 4G products, reducing costs and reaching the industry's expected range.Cat.1 is the user terminal level configured with the lowest version parameters, allowing the industry to design low-end 4G terminals at low cost.

Of course, "low version" 4G terminals with Cat.1 play an important role in the industry. For example, some handset makers are considering using Cat.1 chips to release 4G smartphones for seniors, many of whom require only basic calls and data, and Cat.1 features support low-cost VoLTE and low-rate data, providing a new option for cell phone makers. However, Cat.1 may be even more important in the IoT space.

Compared to NB-IoT and 2G modules, Cat.1 offers advantages in terms of network coverage, speed and latency. Compared with traditional Cat.4 modules, it has the advantages of low cost and low power consumption. At the same time, Cat.1 is suitable for the current home 4G network, which is ideal for application scenarios that require cost-effectiveness, latency, coverage, and communication speed.

Cat.1 Development Prospects

During the study of intergenerational learning migration of cellular IoT technology connectivity, the original 2G/3G connectivity can only be carried out by NB-IoT and 4G. Among them, low frequency, small packet, low mobility, low latency sensitivity, high cost as well as sensitivity of the scenarios we can be carried out at the same time through the NB-IoT; medium rate, certain aspects of the requirements of latency and mobility, the voice and cost of supporting enterprises with a certain ability to withstand the work of the design of the program can choose to carry out through the Cat.1.

4GIoT connectivity has distinct structural characteristics, with Cat.1 being the branch of interest. Looking at the current trends in cellular IoT, the time has opened for Cat.1 to assume a major role in 4GIoT connectivity.
