Internet in Shielded EMC Enclosures: The Role of the Ethernet Cable
In a world where wireless technologies dominate, there are environments where wired connections are not just preferred but necessary. One such scenario is the shielded electromagnetic compatibility tent (EMC tent). In this blog post, we take a look at how Ethernet cables contribute to maintaining a stable and secure internet connection in such shielded environments.
The EMC Enclosure: An Introduction
What is an EMC Enclosure?
EMC enclosures by Shieldex are specially designed spaces intended to block any kind of electromagnetic radiation. This includes Wi-Fi signals, meaning that wireless connections are not possible within these tents. Such tents are often used in areas where sensitive measurements or tests need to be conducted without external electromagnetic interference.
Applications of the EMC Enclosures
Whether in research, military applications, or industry – EMC tents are significant wherever electromagnetic disturbances can affect the accuracy and reliability of tests and measurements.

The Challenge: Internet Access in a Shielded Space
The shielding of an EMC tent presents a particular challenge for internet access. Since wireless signals are blocked, an alternative form of connection must be found to connect devices within the tent to the internet.
The Role of the Ethernet Cable
This is where the Ethernet cable comes into play. Ethernet, a standard for wired data transmission, provides a reliable and stable way to connect devices such as laptops, desktop PCs, routers, and other network-capable peripheral devices.
How Does Ethernet Work in the EMC Tent?
An Ethernet cable can be connected through a specially shielded entry point on the tent. For additional security, it is also routed through a specially shielded cable sleeve that is attached to the Shieldex EMC tent. This configuration allows the cable to be safely led into the tent and connected to the devices located there. In this way, an effective internet connection can be established despite the shielding.
Advantages of Ethernet Connection
Compared to Wi-Fi, Ethernet offers several advantages, especially in shielded environments:
- Stability: Ethernet connections are less prone to interference and offer constant connection quality.
- Security: Wired connections are generally more secure than wireless, as access can be physically controlled.
- Speed: Ethernet often allows higher transmission rates than Wi-Fi, which is important for data-intensive applications.
Using Ethernet in the EMC Tent: A Practical Example
Real-world Application
To illustrate the importance of the Ethernet cable in the EMC tent, consider a practical example. In a research laboratory conducting sensitive electromagnetic measurements, using an EMC tent is essential to exclude external interference signals. Here, the Ethernet cable allows researchers access to online databases and resources while working within the shielded environment.
