About the Shielding Buildings Against Radio Disruption Webinar

The radio environment is crowded.

Electromagnetic Interference (EMI) can cause system malfunction, communications interruptions, loss of data and erroneous measurements. With the increased quantity and mobility of Radio Frequency threats, radio noise protection can be a critical issue in facilities design. Protection in an urban environment, where systems and users are in close proximity to potential threats, requires an understanding of the coupling and physics to find effective solutions.

Everyday examples of interference sources in the urban environment include:

  • TV/Radio and communications transmitters
  • Banks and Financial Institutions
  • Rail and subway systems
  • Research and Medical Facilities
  • WiFi, Cellular and Wireless communications systems


Electromagnetic Pulse (EMP) threats are a continuing concern. Detonation of a nuclear device in the atmosphere can create high amplitude transient threats that can shut down power, control and communications systems.

Threats from Outer Space: Solar storms can create powerful noise sources in the upper atmosphere, wreaking havoc on communications and control systems.

In addition to external noise sources, shielding and radio frequency protection of facilities can reduce the threat of electronic eavesdropping, which is essential for protection of critical information.

This one-hour webinar presents the threat environment and practical measures to mitigate interference from a broad spectrum of noise sources.

Who Should Attend: Architects, Facilities Designers and Planners from:

Military and Government Agencies
Industrial & Commercial Facilities
Financial Institutions
Power Generation

Protection for Facilities & Systems:

Shielding systems are often employed in building facilities to protect sensitive systems from radio frequency sources in the urban environment. Communications security must be robust and free from eavesdropping or disruption.

Protection in the Laboratory:

Research hospitals, biotechnology and life sciences organizations deal with extremely sensitive sensors and systems during research and development. The small signals that are detected in animal-cell activities are measured in billionths of amperes, which can be overwhelmed by intruding signals from mobile networks, WiFi access points, TV/AM/FM broadcast and other sources of man-made noise. Protection in the Workplace Electromagnetic Fields (EMF) are a concern for worker safety and health, as well as potentially interfering with sensitive electrical equipment. High-amplitude AC power currents can generate low frequency magnetic fields that are difficult to control and to reduce. Shielding is one of the options to reduce these fields.

A System Approach

Washington Laboratories takes a systems-level approach to the problems of radiated interference. Our objective is to find the most cost-effective methods of controlling interference.

This webinar will cover the most essential elements of Shielding of Facilities.

  1. Quantifying the threat
  2. System sensitivity and probability of interference
  3. Reduction and control of potential sources
  4. Prudent space configuration to minimize interference coupling
  5. Specifying appropriate materials and construction methods
  6. Quantifying the performance: Measurements
