Radio network and method for transmitting data in a radio network
In a radio network, in which devices transmitting data seize one of a plurality of available frequency channels for the duration of the data transmission, during breaks between the individual data transmissions the frequency channel used is additionally seized in order to signal the seizure of the frequency channel to devices of another radio network. The seized frequency channel is monitored for the attempt of seizure by a device that is not part of the radio part and the additional seizure of the frequency channel is performed as a function of the detection of such an attempt.
1. A radio network, comprising:
frequency channels;
devices transmitting data which use one of the frequency channels for a duration of a data transmission; and
a monitoring facility which additionally seizes the used frequency channel during pauses between data transmissions, wherein
the monitoring facility is configured
to monitor the used frequency channel for an attempted seizure by a device which does not belong to the radio network and
to perform an additional seizure of the frequency channel as a function of a detection of the attempted seizure by the device which does not belong to the radio network.
2. The radio network as claimed in claim 1 , wherein the monitoring facility is configured to increase a transmission power during the additional seizure.
3. The radio network as claimed in claim 1 , wherein the monitoring facility is configured to perform the monitoring of the frequency channel of the radio network during the pauses between the data transmissions.
4. The radio network as claimed in claim 2 , wherein the monitoring facility is configured to perform the monitoring of the frequency channel of the radio network during the pauses between the data transmissions.
5. The radio network as claimed in claim 1 , wherein the functionality of the monitoring of the seized frequency channel for an attempted seizure by a device which does not belong to the radio network and the functionality of the additional seizure of the frequency channel are implemented in at least one of the devices of the radio network.
6. The radio network as claimed in claim 1 , wherein the functionality of the monitoring of the seized frequency channel for an attempted seizure by means of a device which does not belong to the radio network is implemented in at least one of the devices of the radio network and the functionality of the additional seizure of the frequency channel is implemented in a device which is separate from the radio network.
7. The radio network as claimed in claim 1 , wherein the functionality of the monitoring of the seized frequency channel for an attempted seizure by means of a device which does not belong to the radio network is implemented in a device which is separate from the radio network and the functionality of the additional seizure of the frequency channel is implemented in the at least one of the devices in the radio network.
8. The radio network as claimed in claim 1 , wherein the functionality of the monitoring of the seized frequency channel for an attempted seizure by a device which does not belong to the radio network and the functionality of the additional seizure of the frequency channel are implemented in a device which is separate from the radio network.
9. A method for transmitting data in a radio network, comprising:
providing several frequency channels and devices transmitting data;
using one of the several frequency channels for a duration of a data transmission by the devices, the used frequency channel also being seized during pauses between data transmissions,
monitoring the used frequency channel for an attempted seizure by a device which does not belong to the radio network, wherein an additional seizure of the frequency channel takes place as a function of a detection of the attempted seizure by the device which does not belong to the radio network.
10. The method as claimed in claim 9 , further comprising:
increasing a transmission power during the additional seizure.
11. The method as claimed in claim 9 , wherein the monitoring of the used frequency channel of the radio network takes place in the pauses between the data transmissions.
12. The method as claimed in claim 10 , wherein the monitoring of the seized frequency channel of the radio network takes place in the pauses between the data transmissions.
