Security and interfering networks are challenges in wireless networks today. A security technique concerning shielding wireless signal using signal reducing or canceling material can be used to solve some of these issues. This technique however, is regarded as expensive and hard to implement. To look into these claim, several types of shielding solution were tested and compared in regard to efficiency, cost and implementation. Testing of the solution was done using a test box with the solutions applied to the interior. As a result of the study it was found that affordable shielding solutions with decent attenuation and uncomplicated implementation exists. For higher attenuation performance more expensive materials, installed by professionals, are needed.
