In the field of Industrial Internet of Things (IIoT), IoT Modem play a pivotal role. They serve as bridges, connecting industrial devices to data centers, ensuring real-time data transmission and remote monitoring. However, in the face of complex and ever-changing industrial environments, the stability and reliability of IoT Modem have become crucial factors that cannot be ignored. So, among the numerous products available, which IoT Modem is trustworthy? Let's find the answer through a series of stability and reliability tests.
Firstly, we need to focus on the stability of IoT Modem. In IIoT applications, IoT Modem need to maintain a connection with the data center for extended periods to ensure real-time data transmission. Therefore, we can assess the stability of IoT Modem through heartbeat maintenance tests and link persistence tests.
Heartbeat Maintenance Test:
When there is no data transmission, the IoT Modem maintains its connection with the data center through heartbeat signals. A high-quality IoT Modem should be able to maintain a link duration of at least one hour without disconnection and reconnection. USR-G771 excels in this test, with its stable heartbeat signal ensuring continuous connection with the data center.
Link Persistence Test:
The rapid recovery capability of the IoT Modem is also important after the data center suspends service. We simulated a scenario where the data center was closed for one minute and then restored. USR-G771 was able to reconnect quickly, with a recovery time far below the five-minute standard, and achieved 100% reconnection in multiple tests.
In addition to stability, the reliability of IoT Modem is also crucial. In industrial environments, the integrity of data transmission and rapid recovery capabilities are vital.
Small Data Packet Test:
We simulated scenarios of frequently sending and receiving small data packets during daily operations. Between the data center and USR-G771, a data packet of approximately 100 bytes was sent every 10 seconds for 10 minutes. USR-G771 performed excellently in this test, with no disconnections or data packet losses.
Big Data Stress Test:
For applications requiring temporary transmission of large amounts of data, we conducted a big data stress test. Between the data center and USR-G771, a data packet of approximately 1000 bytes was sent every two seconds for 30 minutes. Under pressure, USR-G771 maintained a stable connection, with disconnection and reconnection times far below the standard of 10 times, and data transmission speeds ranging from 300 to 1500 bytes per second.
In addition to basic stability and reliability testing, we also need to focus on the industrial-grade design and environmental adaptability of IoT Modem.
Industrial-Grade Power Chip:
USR-G771 adopts an industrial-grade power chip that supports wide voltage operation, ensuring normal device operation even under unstable voltage conditions.
Wide Temperature Protection:
After rigorous testing, USR-G771 supports startup and continuous stable operation under extreme temperatures. It can ensure the stability of data transmission in environments ranging from extremely cold (-40°C) to high temperatures (70°C).
EMC Class 3 Protection:
USR-G771 adopts a port isolation mechanism, achieving lightning and surge protection designs, with 15KV electrostatic protection, effectively reducing the impact of external interference and electromagnetic interference on device stability.
In addition to the above tests, USR-G771 also has a series of other functional characteristics that make it a trustworthy IoT Modem product.
Fast Response and Automatic Reconnection:
USR-G771 has an ultra-fast response speed, connecting to the user center shortly after device startup. Once the network is interrupted, it can reconnect to the network in the shortest possible time, ensuring continuous data transmission.
Remote Device Management:
USR-G771 supports remote device management functions. Even when the network is interrupted, administrators can still remotely view device status, disconnection times, and download, backup, and modify configurations through the device management platform.
Multiple Connection Strategies and Protocol Support:
USR-G771 supports multiple connection strategy modes, including polling mode and concurrent mode. Additionally, it supports multiple protocols such as TCP/UDP/DCTCP/DCUDP, providing more flexible data transmission and communication capabilities.
USR-G771 has excelled in IoT Modem stability and reliability testing, becoming a trustworthy IoT Modem product with its outstanding performance and rich functional characteristics. Whether in fields such as intelligent manufacturing, energy, transportation, or environmental monitoring, USR-G771 ensures smooth data transmission and facilitates remote monitoring and management.
