CB gateway
CB gateways are automatically operated CB radios that are networked with one another via the Internet. The Internet can serve as a virtual radio link and transmit voice (through the network) over great distances. By transmitting ("tunneling") CB radio transmissions over the Internet, the range of action of CB radio devices is considerably extended.
principle
The radio at location A receives the voice. The loudspeaker output of this radio device is connected to the LINE-IN input of a computer and the audio-voice signal is digitized in the computer and transmitted through the Internet in a similar way to Voice-over-IP transmissions. The principle is similar to the amateur service used EchoLink . With CB gateways, however, there is no uniform structure, but rather many competing systems and servers. Much like in chat rooms you can connect multiple virtual rounds and then gets the corresponding audio signal to his radio at the site B transmitted. The PC takes over the analog / digital conversion; an adapter between PC and radio device keying the transmitter and transmitting the voice signal.
For the operator of CB gateways, after installing and configuring the software (e.g. Free Radio Network , eQSO , Mumble , Teamspeak or Virtual CB Funk) and assembling the audio adapter, the construction of the gateway is already complete.
Some operators of central servers have joined together to form what are known as voice radio networks. They want to create a network of CB gateways that will enable CB radio operators to conduct connections across Europe with low transmission power (currently mainly in Germany, Austria and the Benelux countries).
Legal aspects in Germany
The legal situation of CB gateways was controversial until the end of 2006. In the CB radio regulations, the Federal Network Agency (BNetzA) as the supervisory authority stipulated that voice transmissions between CB radio systems may only take place directly . Voice transmission between CB radios via unmanned, automatically operated stations or other intermediary networks was not permitted. In April 2006 the shutdown of a gateway was ordered by the Federal Network Agency. By coupling the radio with the PC, the radio system was operated in the 'Voice via Internet (VoIP)' mode and, according to the BNetzA, this mode of operation was not assigned to the CB radio in the general allocation. Nevertheless, the authority did not intend to specifically ban CB gateways when drawing up the regulations. For this reason, to clarify the legal situation of CB gateways, on December 20, 2006 it partially changed the regulations for CB radio and released four channels for gateway operation.
On January 16, 2008, the number of gateway channels was increased from four to seven. Since then, gateway operation on channels 11, 29, 34, 39, 61, 71 and 80 has been permitted in Germany.
As of April 1, 2016, nine gateway channels will be possible in Germany. Gateway operation is permitted on channels 11, 29, 34, 39, 40, 41, 61, 71 and 80.
