In the field of industrial IoT, selecting the right modem is crucial to ensuring the networking performance of devices. This article will compare 4G and Cat-1 technologies in depth to help people who need to make informed purchasing decisions for networking applications.

1. Overview of 4G technology

4G, also known as LTE network, is the fourth generation of mobile communication technology, which can provide high-speed data transmission, enabling users to browse the Internet, download and upload large files faster. 4G technology is mainly divided into two parts: TD-LTE and FDD-LTE. Compared with 3G communication technology, it has more advantages and is a perfect combination of WLAN technology and 3G communication technology. In smart communication devices, 4G communication technology can increase the user's Internet usage speed to 100Mbps.

2. Overview of Cat-1 technology

Cat-1, also known as LTE UE-Category 1, where UE refers to user equipment, is a classification of the wireless performance of user terminal equipment in LTE networks. Cat-1 belongs to the 4G series, which can fully reuse existing 4G resources. Its original design intention is to serve the Internet of Things and achieve low-power and low-cost LTE connectivity, which is of great significance for the development of the Internet of Things.

As a simplified version of 4G, Cat-1 can be quickly brought to market after the 4G industry chain matures, with only minor modifications to existing 4G products, reducing costs and meeting industry expectations. Cat-1 supports low-cost VoLTE and low-rate data transmission, configured with minimal version parameters, allowing the industry to design low-cost 4G low-end terminals.

3. Comparison between 3G and 4G and Cat-1 frequency band

Data transmission speed:

4G networks can provide data transmission speeds of up to tens to hundreds of megabits per second (Mbps), making them suitable for applications that require high-speed data transmission.
Cat-1 speeds are more suitable for IoT devices, typically ranging from tens to hundreds of kilobits per second (Kbps). This is because most IoT needs do not require high-speed data transmission, such as sensor data uploading, telemetry, and remote monitoring.

Power consumption and efficiency:

Although the 4G network has fast data transmission speed, its power consumption is relatively high, which has a certain impact on the battery life of the device.
Cat-1 has been optimized and improved in terms of power consumption and efficiency, providing long-term stable connectivity at lower power consumption, which is crucial for the battery life and stability of IoT devices.

Coverage and signal strength:

4G networks usually have a wider coverage range, but in some edge areas or indoor environments, signal quality may be affected.
Cat-1 typically has a broader coverage area and stronger signal penetration capability, maintaining good signal quality even in indoor and edge areas. This is due to its lower operating frequency band and its greater suitability for providing reliable connections.

Price and applicability:

The price of 4G modules is relatively high, and it is suitable for application scenarios that require high-speed data transmission and wide coverage.
Cat-1 provides lower data transmission speed, lower power consumption, and relatively lower price, making it more suitable for IoT devices that require large-scale deployment, such as smart homes, smart meters, and industrial automation.

4. Suggestions for purchase

When selecting an industrial Modem, it is necessary to weigh the specific application scenarios and requirements. If high-speed data transmission and wide coverage are required, 4G network is a better choice. If you focus more on low power consumption, low cost and stable connectivity, Cat-1 is a more suitable choice.

In addition, it is also necessary to consider the compatibility, reliability, and technical support of the Modem. Choosing a brand with a good reputation and rich experience can ensure the stability and long-term availability of the equipment.

In the field of industrial Internet of Things, choosing the right Modem is crucial to ensuring the networking performance of devices. By deeply understanding the characteristics and advantages of 4G and Cat-1 technologies, it can help people who need to make smart purchasing decisions for networking applications.
