Our daily life can no longer be separated from intelligent technology, especially since the epidemic, intelligence has become particularly important.

Self-service shopping terminals allow us to reduce personnel contact and complete the purchase of items; smart wearable devices can help us monitor our physical health; shared terminal devices can bring more convenience to our lives... These are all applied to a technology - Cat.1.
Cat.1 is a classification used to measure the wireless performance of user terminal equipment, and its full name is LTE UE-Category1. The peak uplink rate of Cat.1 is 5Mbit/s, the peak downlink rate is 10Mbit/s, and the delay is about 50 to 100 milliseconds. It is a network standard to meet the needs of medium and low bandwidth IoT devices.

In 2021, the global Cat.1 will be in an outbreak period, with shipments reaching 120 million. In the Chinese market alone, Cat.1 shipments will reach 110 million in 2021. Domestic Cat.1 modules have only begun to exert their strength at the end of 2019. According to the "Global Cellular IoT Module Tracking Report 2021" released by IoT Analytics, Cat.1 modules will account for 12% of the shipments in the Chinese market in 2021. In a year and a half, Cat.1's market share ballooned from blank to 12%.

2G/3G network withdrawal is the main reason for the full outbreak of Cat.1, 30% of the medium-speed cellular connection market that GSM is responsible for needs to be filled, and 4G LTE is recognized by the industry as a technology that will carry mainly voice and medium-speed scenarios. Cat.1 and Cat.4 can be used in LTE medium-speed connection scenarios, but in scenarios such as smart wear, sharing economy, industrial control, logistics tracking, etc., Cat.1 can meet certain high-speed mobile needs, is sensitive to delay, and supports voice , pay more attention to low cost and low power consumption.

Why is Cat.1 the best seed in the mid-rate scenario?
First of all, Cat.1 is not a new technology. It has been "latent" for ten years. Now it can reuse the current mature 4G base stations. At the same time, its protocol development has been stable, and it can seamlessly access 3G/4G networks. . Secondly, eMTC's domestic industrial ecological chain is not complete and does not have a competitive advantage. NB-IoT is mainly aimed at the low-speed cellular connection market. It is currently complementary to Cat.1, and it is synergistic in key areas such as smart home, industrial manufacturing, fire smoke detection, logistics tracking, and financial payment.

Cat.1 has been favored by many players and has become a "red man" for communication operators, chip manufacturers, module manufacturers and terminal manufacturers. It will rapidly break through the billion-dollar market in the past two years. At present, Chengdu Ebyte Electronic Technology Co., Ltd. has also launched a variety of  4G DTU Modem products, which are used in multiple verticals such as two-wheelers, wireless payment, public network intercom, charging pile, cloud speaker, and smart energy.
