Simple Test of Wireless Devices in RF shielded enclosures
The fundamentals in a simple and cost-efficient test-system of wireless devices are a RF shielded box and an antenna coupler. Ideal for GO / NO GO test of wireless devices using: Bluetooth, WLAN, UWB, RFID, Zigbee, 2/3/4/5G, LTE, GSM, GPS..
TESCOM - RF Shielded Boxes:
The most important feature of the shield box is the shielding of external interference signals, that can affect the test of the DUT. Depending on the measurement locations and testing environment, various signal interferences occur such as surrounding DUT signal, base station signal, and another measuring device´s signal, distorting the testing signal and lowering the reliability of measurement. However, the TESCOM shield box has secured stable shielding performance by using shield gasket and EMI filter in areas vulnerable to external interference signals such as I/O connectors, joints, and around doors. TESCOM has a wide range of shielded boxes for different sizes of DUT’s and I/O connections.
Sub-6GHz & UWB Shield Boxes
These shield box supports a range of up to 12 GHz to enable testing on forward-looking technologies such as 5G, UWB, and WIFI 6E variants.
The following images show the different sizes of our Shield Boxes
Featured Models
5G mmWave Shield Boxes
Manual-operation shield boxes optimized to perform 5G tests between 0.1 GHz to 67 GHz on larger devices such as tablets, laptops, and desktops.
Antenna & RF Coupler
The flat type antenna couplers can make a well-defined radiated connection to the DUT in the shielded box, without using any physical RF connector. It can be used for multi frequency bands DUT as well. We offer wide range of Single and Dual Polarized Vivaldi Antenna with a frequency range specification of 0.7 GHz up to 6 GHz
mmWave Horn Antenna
We also offer a wide range of broadband quad-ridged horn antennas with frequency range from 24 GHz – 44 GHz and rectangular horn antennas spanning 24 GHz – 67 GHz for 5G/mmWave testing.
Tescom manufactures high-quality RF shield boxes in various sizes and input/output configurations.

FAQ
What is an RF Shield Box, also called RF shielded enclosure, and why is it needed?
An RF shielded box is an enclosure that isolates wireless devices from external electromagnetic interference, enabling accurate and repeatable testing of signal strength, bandwidth, and performance by preventing outside signals from affecting results.
What types of wireless devices can be tested inside these shielded boxes?
RF shielded boxes from TESCOM can accommodate a wide range of devices, including Bluetooth, WLAN, UWB, RFID, Zigbee, 2G/3G/4G/5G, LTE, GSM, and GPS-enabled devices, as well as tablets, laptops, and desktops depending on box size.
Is Tescom RF box designed for Ultra-wideband (UWB) testing?
Yes. Tescom RF Shield Boxes are engineered to support UWB testing with a frequency range up to 12 GHz. This makes them ideal for validating devices using UWB technology, as well as other wireless standards like Wi-Fi, Bluetooth, Zigbee, and 5G. They provide high RF isolation, stable shielding performance through EMI-filtered I/O, and absorber-lined chambers for consistent UWB measurements. Whether you need a compact solution for smartphones or larger enclosures for tablets and IoT devices, Tescom offers models optimized for Sub-6GHz and UWB testing.
Can the same RF chamber support different antenna types and polarizations?
Yes. A single RF chamber can support multiple antenna types, including omnidirectional, Vivaldi, spiral, and other custom antenna solutions. The antenna selection depends on the test objective, frequency range, radiation pattern, and polarization requirements.
For example, linearly polarized antennas are often used for RSSI and receiver sensitivity testing when the DUT orientation is controlled, while circularly polarized antennas can be advantageous for OTA testing when DUT orientation may vary. Using interchangeable fixtures and antenna mounts, the same chamber can be adapted to different antenna configurations without modifying the chamber itself.
What are the main benefits of using a shield gasket and EMI filter?
Shield gaskets and EMI filters reinforce areas prone to signal leakage, such as connectors and seams, reducing the risk of measurement distortion and increasing the consistency and reliability of wireless device tests.
What frequency ranges do these shielded boxes support?
TESCOM shielded boxes support broad frequency ranges, including sub-6 GHz and mmWave. Certain models cover up to 12 GHz for next-generation wireless technology, while specialized boxes can handle up to 67 GHz for 5G mmWave testing.
Are the boxes suitable for testing advanced wireless technologies?
Yes, TESCOM boxes are suitable for testing advanced technologies such as 5G (sub-6GHz and mmWave), UWB, WIFI 6E, LTE, GSM, and GPS, thanks to their wide supported frequency range and customizable antenna couplings.
What factors influence RF test performance inside a shielded chamber?
Accurate RF measurements depend on more than antenna selection. Antenna polarization, antenna positioning, DUT placement, fixture design, chamber size, and antenna beamwidth can all impact RSSI, receiver sensitivity, and OTA test results.
When designing a test setup, engineers must consider whether the application requires omnidirectional, directional, linearly polarized, or circularly polarized antennas, including RHCP and LHCP configurations. The objective is to create a repeatable RF environment that accurately represents the DUT's real-world operating conditions and delivers consistent measurement results throughout development, validation, and production testing.
Which models are suitable for 5G mmWave testing?
TESCOM offers manual-operation shielded boxes specifically optimized for 5G mmWave testing in the 0.1 GHz to 67 GHz range, suitable for larger devices such as tablets and laptops.
What frequency ranges do the horn antennas support?
TESCOM provides quad-ridged horn antennas with frequencies from 24 GHz to 44 GHz and rectangular horn antennas covering 24 GHz to 67 GHz for advanced mmWave testing applications.
