LED Signage

Industries such as transportation or finance often use LED signage to present information, such as traffic congestion information or real-time stock quotes. Cellular technology can allow such messaging and communication for previously untapped, hard-to-wire locations, such as on highways and on buildings. Message display can be controlled in real-time from a remote monitoring location. A Robustel Gorugged M1000 Smart GPRS Modem can be used for simple setups that do not require advanced computing functions.
