Knowledge of ambient optical noise is essential for designers of free space optical links, for resilient designs. In this paper, a complete experimental
characterisation of the most common ambient optical radiation is presented. The study includes Tungsten filamen t sources, low and high frequency
fluorescent lights, IR headphones, TV remote controls, and daylight. Means to reduce their influence on the performance of the links are also given.
The results are valuable towards setting a standard way of comparing wireless IR links, based on testing their performance under such ambient noise.
