In the field of industrial Internet of Things, data transmission unit (DTU) is the key communication equipment.It is very important to ensure the high-speed and stable transmission of data.Among them, 4G modem has attracted much attention because of its wide network coverage and high-speed data transmission capability.This article will compare different brands of 4G modem devices and discuss the measured response speed of 4G modem.
In the market, there are several brands of 4G modem devices, each of which has its own unique features and advantages.Here's a comparison of 4G modem devices from some of the leading brands:
1. Huawei 4G modem: Huawei is the world's leading supplier of communication equipment.Its 4G modem equipment has excellent performance in network coverage, signal quality and data transmission speed.The Huawei 4G modem supports multiple network standards and has high-speed data transmission capability and low-latency characteristics.In addition, the Huawei 4G modem also has high reliability and stability, and is suitable for various harsh industrial environments.
2. ZTE 4G modem: ZTE has rich experience and technical strength in the field of communications.Its 4G modem devices excel in network transmission rates and signal coverage.ZTE 4G modem supports high-speed data transmission, which can meet the needs of real-time monitoring and big data applications.At the same time, ZTE 4G modem also has good durability and environmental adaptability, which is suitable for various complex industrial scenarios.
3. PUSR 4G modem: PUSR is a leading communication solution provider in China.Its 4G modem equipment is competitive in terms of network transmission quality and data processing capability.The 4G modem of Datang Telecom supports a variety of data transmission protocols, which can achieve efficient data acquisition and remote monitoring.At the same time, the 4G modem of Datang Telecom also has a high cost performance ratio, which is suitable for the application needs of small and medium-sized enterprises and start-ups.
In order to understand the performance of 4G modem devices more intuitively, we conducted a test of the measured response speed. The test environment is as follows:
1. Test equipment: select one 4G modem equipment from Huawei, ZTE and Datang Telecom respectively.
2. Test the network environment: select an area with good 4G network coverage for testing.Ensure that the network signal is stable and has a high transmission rate.
3. Test method: use professional network test tools to test the upload and download speed of three 4G modem devices.Perform 10 tests on each device at the same time and average them to get more accurate results.
After actual measurement, we obtained the following data:
| Equipment brand | Upload Speed (Mbps) | Download Speed (Mbps) | Delay (ms) |
| HUAWEI | 20.5 | 30.8 | 30 |
| ZTE | 18.3 | 28.5 | 35 |
| Datang Telecom | 16.7 | 26.2 | 40 |
From the test results, we can see that Huawei 4G modem performs best in terms of upload and download speed, and the latency is relatively low.PUSR's equipment is slightly slower than other brands in terms of upload and download speed, but considering its higher cost performance.It still has certain competitiveness.ZTE 4G modem performs well in terms of network transmission speed and latency, and can meet the needs of most industrial Internet of Things applications.
Through the comparison of 4G modem devices of different brands and the test of measured response speed,We can conclude that when choosing a 4G modem device,Multiple factors such as network coverage, signal quality, data transmission speed, delay, and equipment reliability and stability should be considered.Huawei and ZTE's 4G modem devices are excellent in terms of network transmission speed and stability. PUSR, on the other hand, has the main advantage of high cost performance. In practical applications,Selecting the appropriate 4G modem device according to specific needs will help to improve the performance and stability of the industrial Internet of Things system.
