Outdoor notification signs have grown into a huge advertisement medium for businesses, schools, stadiums and other industrial and commercial facilities worldwide. A major manufacturer of electronic signage display systems needed to develop a cost effective wireless based signage system and after trials of several different radio modules decided to use the DNT90 radio modules.
The key requirements of avoiding wired or cellular connections, reliable outdoor operation and ease of installation and system development were met by using a pair of DNT90 radios and using them to deliver the signage content to the outdoor signs wirelessly.
A DNT90 radio module was designed into the display circuitry located outdoors at the signage post. This radio module received content updates form the base controller containing another DNT90 radio embedded into the circuitry and connected to a controlling PC.
