motorways communication systems
Efficient data transmission is one of a basic conditions for the functionality of traffic management systems. The most effective solution is fiber optic networks, ensuring high data transfer and reliable level of protection against electromagnetic interefernces and electrostatic surges. Professional communication systems use fiber optic lines and advances communication devices, creating a redundant communication network, ensuring reliable operation and high speed data transfer, sufficient for the purposes of communication within contemporary designed traffic management systems.
In the absense of available fiber infrastructure, road communication systems are being designed using a public GSM cellular networks and packeting data services which in case of availability of a 3G signal and limited system functionality, gives interesting possibilities for use in the road electronic systems.
