An Authorization To Test (ATT) number is a permit often required before operating certain types of radio transmitting equipment. It serves as documented permission granted by regulatory agencies allowing the temporary use of radio frequencies for testing, demonstration, or experimental purposes. For instance, a company developing a new wireless device might need this before publicly demonstrating its functionality.
Acquiring this authorization is vital for ensuring compliance with radio frequency regulations, preventing interference with existing licensed services, and avoiding potential penalties or legal repercussions. Historically, the need for this type of authorization arose from increasing congestion in the radio frequency spectrum, requiring structured management of its usage. It protects existing services and allows for innovation in a controlled manner.
