What Is an RF Standalone Shield Box?
An RF Standalone Shield Box is a self-contained, rugged enclosure designed to isolate a device under test (DUT) from ambient radio frequency interference during wireless testing. Built from welded aluminium and lined with multi-layer RF absorbers, it creates a controlled electromagnetic environment blocking external signals across frequencies from 100 kHz to 6 GHz. Whether you are validating a 5G module, certifying a WiFi router, or testing an RFID tag, a standalone shield box ensures your results are accurate, repeatable, and free from environmental RF noise.
RF Isolation manufactures a full range of standalone shield boxes from compact bench-top units to large-format enclosures, each fully customizable to your device dimensions, port configuration, and frequency requirements. Our boxes are engineered and tested in-house at our ISO 9001:2015 certified facility in Ahmedabad, India, and shipped to customers across India, USA, UK, Turkey, Australia, Italy, and Israel.

Where RF Standalone Shield Boxes Are Used
From advanced 5G labs to production line quality control, RF Isolation’s standalone shield boxes serve engineers and technicians across industries worldwide.
5G & 4G NR Device Testing
5G module manufacturers and telecom OEMs need to validate OTA (Over-the-Air) performance under controlled RF conditions. Our shield boxes eliminate ambient 5G, LTE, and NR signals from the test environment ensuring your module is evaluated on its own performance, not its surroundings. Trusted by Reliance Jio, Nokia, and C-DOT.
WiFi & WLAN Testing (802.11a/b/g/n/ac/ax)
WiFi device manufacturers and certification labs use standalone shield boxes to run repeatable throughput, sensitivity, and co-existence tests without interference from surrounding WiFi networks. Our enclosures support the full 802.11 protocol stack from legacy 2.4 GHz 802.11b to WiFi 6E at 6 GHz.
Bluetooth & Zigbee Device Certification
Bluetooth 5.x, BLE, and Zigbee devices require clean RF environments for sensitivity testing and certification. Our compact models (RI 1109, RI 1212) are purpose-sized for small wireless modules and provide the isolation levels required by certification bodies including BQB and FCC.
RFID & NFC Device Testing
RFID readers and tag manufacturers use RF shield boxes to simulate controlled read-range scenarios, test antenna patterns, and verify device sensitivity isolating the DUT from the ambient RFID environment in a warehouse, retail, or logistics setting.
IoT Device R&D and Certification
IoT product teams use standalone shield boxes throughout the development cycle from early-stage RF validation to pre-compliance testing before formal certification at accredited labs. Catching RF issues early with a shield box saves weeks of lab time and certification delays.
Defence & Aerospace RF Testing
Military-grade and aerospace electronic systems require RF shielding environments that meet strict attenuation standards. Our enclosures with copper beryllium contact technology and welded construction deliver the consistent high isolation performance required in these demanding applications.
Why Engineers and Procurement Teams Choose RF Isolation
Verified Isolation - Every Unit, Before Dispatch
Every RF Isolation shield box is tested at our in-house measurement facility before it leaves our Ahmedabad plant. You receive a shielding effectiveness report with your unit not just a claimed spec sheet.
ISO 9001:2015 Certified Manufacturing
Our production facility is ISO 9001:2015 certified meaning every process from raw material procurement to final QA inspection follows documented, audited quality procedures. Your box is built to the same standard every time.
Fully Custom - Not Just 'Configurable'
We have built enclosures from 110 mm to 700 mm+ internal dimensions for clients ranging from Reliance Jio to defence electronics contractors. If your device does not fit a standard model, we will design and build one that does with your exact port layout, absorber specification, and size.
Expert Technical Support - Pre and Post Sale
Our engineering team provides free consultation before your purchase to help you select the right model and configuration. After delivery, we provide installation support, door maintenance guidance, and can visit your site for larger installations.
Trusted by India's Leading Technology Companies

Frequently Asked Questions
What isolation level do I need for 5G Sub-6 GHz device testing?
For 5G Sub-6 GHz testing, we recommend a minimum of 90 dB isolation at 6 GHz. Our standard standalone shield boxes deliver ≥90 dB at 6 GHz and ≥120 dB at 3 GHz exceeding the requirements for most 5G NR protocol compliance and OTA sensitivity testing. If you are running carrier aggregation tests across multiple bands simultaneously, contact us for a custom high-isolation configuration.
Can the shield box be customised to my device dimensions?
Yes - fully. We manufacture custom RF standalone shield boxes to any internal dimension you specify. Provide us with your device's length, width, and height (including any connected cables or antennas), your required frequency range, and your port configuration. Our team will design and quote a custom enclosure, typically within 24 hours. Lead time for custom builds is 4–6 weeks.
What is the difference between an RF Standalone Shield Box and a Desktop Shield Box?
An RF Standalone Shield Box is a self-contained, free-standing enclosure suitable for bench-top use, trolley mounting, or integration into a test rack. It is available in a wider range of sizes and configurations. An RF Desktop Shield Box is a more compact, fixed-orientation unit specifically designed for WLAN and WiFi testing with a manual door mechanism. If you need flexibility in DUT size and mounting options, the standalone box is the right choice.
What is the typical delivery timeline?
Standard models (all 13 listed models) are typically available within 2–3 weeks for domestic India delivery. Custom-built enclosures have a lead time of 4–6 weeks depending on complexity. International shipping to USA, UK, Turkey, Australia, Italy, and Israel is available shipping timelines vary by destination. Contact us for a firm delivery date for your order.
Do you provide a free trial before purchasing?
Yes. We offer a free prototype trial for qualified customers you can evaluate the shielding performance of a selected model in your actual test environment before committing to a purchase. To apply for a free trial, click the 'Request Free Trial' button or contact our team on WhatsApp.
How do I maintain the shielding effectiveness of the box over time?
The most critical maintenance item is the RF door's copper beryllium contact fingers. These should be inspected every 6 months for deformation or contamination and replaced if shielding performance drops. The door gasket seal should also be cleaned regularly. RF Isolation offers a door and accessories maintenance service our team can visit your site or provide replacement parts and guidance remotely.
What certifications do your products carry?
RF Isolation is ISO 9001:2015 certified for our manufacturing quality management system. Our products are supplied with a Certificate of Compliance confirming the shielding effectiveness meets the stated specification. We can provide third-party measurement reports on request. Our products are designed in compliance with international RF shielding standards for global markets.
Do you ship internationally?
Yes. We regularly export to USA, UK, Turkey, Australia, Italy, and Israel and can ship to most countries worldwide. International orders are packed in reinforced crating to protect the shielded enclosure during transit. Contact us with your destination country for a shipping quote and timeline.
Which model should I choose for WiFi 6 (802.11ax) testing?
For WiFi 6 and WiFi 6E testing (operating up to 6 GHz), we recommend the RI 5550 or RI 5639 for most standard devices. These models deliver ≥125 dB at 1 GHz and ≥90 dB at 6 GHz, making them ideal for 802.11ax sensitivity and throughput testing. For devices with external antennas or larger form factors, consider the RI 6060 or RI 6149.
Can the box be integrated into a test rack or automated test system?
Yes. All RF Isolation standalone shield boxes are available in rack-mount compatible configurations. We also offer a dedicated Rack Mount RF Shield Box product line designed for integration into 19-inch equipment racks and automated test systems with motorised door options. Contact us to discuss your system integration requirements.
