A data communication system and a method of data communication. The method comprises receiving data associated with a plurality of users, wherein a first set of the plurality of users is located at a first location and a second set of the plurality of users is located at a second location. The method further comprises determining that the first set of users has access to both a broadband data communication system and a trunked radio system and that at least one user of the second set of users does not have access to the broadband data communication system. The data is then provided to the first set of users by the broadband data communication system and not the trunked radio system, and to the second set of users by the trunked radio system and not the broadband data communication system. |
