Radio communications in « DUPLEX » mode
In a system named "DUPLEX", all devices belonging to a group communicate with each other directly between each other, but through a repeater. Its role is to receive communications from this group and the rebroadcast to all other devices this one.
Compared to a "Simplex" system whose coverage is only a few kilometers, the coverage of a "DUPLEX" system extends from 40 to 60 kilometers, depending on the conditions of the place where the repeater is located (climate, topography, natural barriers).
Electronique Mercier has on its territory several repeater sites. A repeater can be shared between several users, each associated with an identification number (ID) allowing privacy from other groups with access to this repeater.
This solution is less expensive than installing a private repeater and its perfect for an organization using a small quantity of radios. A "DUPLEX" system is ideal for users who need to travel over a large area or who need a wider communication with other users in their group.
In addition, the "DUPLEX" system allows radios users to be connected to the telephone network, and without adding additional modules on their radios. This technology is very useful for users with a mobile or portable radio and without cell phone and greatly reduced costs.
Electronique Mercier has many solutions like these ones to meet your needs in radio over long distances at low costs.
