Over the Internet TCP is used and the messages can’t be broadcasted in the same way they are in local networks. Locally UDP Broadcast is used.
Through the use of a Mimer RadioServer or a Mimer NetworkRepeater more than one computer can be connected.
With UDP all status and audio messages are broadcasted to all operators in the subnet without the need to log on or log off. You can have many operators to each radio. But UDP can not pass through routers used in WAN or Internet systems.
With TCP you can pass through routers and you need to log on with a password and to set up ports in the routers. The Mimer NetworkInterface can only handle one TCP connection and there for you need a server when there are several operators.
