A method comprising: detecting, by a radio-channel monitoring device, communication data broadcast on a first radio channel by a radio device associated with a first user; and in response to determining, by the radio-channel monitoring device, that the communication data meets given criteria for rebroadcasting: determining, by the radio-channel monitoring device, additional context data associated with one or more of the radio device and the first user; identifying, by the radio-channel monitoring device, two or more second radio channels for rebroadcast of the communication data; and causing, by the radio-channel monitoring device, at least a portion of the communication data and the additional context data to be broadcast on the two or more second radio channels, the at least a portion of the communication data and the additional context data being broadcast in a channel-compatible format on the two or more second radio channels, the additional context data one or more of preceding, succeeding and being embedded in the portion of the communication data wherein the additional context data is varied for each of two or more of the second radio channels based on one or more of: an associated function of each of the two or more of the second radio channels; one or more of associated roles and associated identities of other users associated with each of the two or more of the second radio channels; and context data associated with the other users associated with each of the two or more of the second radio channels. detecting, by a radio-channel monitoring device, communication data broadcast on a first radio channel by a radio device associated with a first user; and in response to determining, by the radio-channel monitoring device, that the communication data meets given criteria for rebroadcasting: determining, by the radio-channel monitoring device, additional context data associated with one or more of the radio device and the first user; identifying, by the radio-channel monitoring device, two or more second radio channels for rebroadcast of the communication data; and causing, by the radio-channel monitoring device, at least a portion of the communication data and the additional context data to be broadcast on the two or more second radio channels, the at least a portion of the communication data and the additional context data being broadcast in a channel-compatible format on the two or more second radio channels, the additional context data one or more of preceding, succeeding and being embedded in the portion of the communication data wherein the additional context data is varied for each of two or more of the second radio channels based on one or more of: an associated function of each of the two or more of the second radio channels; one or more of associated roles and associated identities of other users associated with each of the two or more of the second radio channels; and context data associated with the other users associated with each of the two or more of the second radio channels. determining, by the radio-channel monitoring device, additional context data associated with one or more of the radio device and the first user; identifying, by the radio-channel monitoring device, two or more second radio channels for rebroadcast of the communication data; and causing, by the radio-channel monitoring device, at least a portion of the communication data and the additional context data to be broadcast on the two or more second radio channels, the at least a portion of the communication data and the additional context data being broadcast in a channel-compatible format on the two or more second radio channels, the additional context data one or more of preceding, succeeding and being embedded in the portion of the communication data wherein the additional context data is varied for each of two or more of the second radio channels based on one or more of: an associated function of each of the two or more of the second radio channels; one or more of associated roles and associated identities of other users associated with each of the two or more of the second radio channels; and context data associated with the other users associated with each of the two or more of the second radio channels.
