Content originated by a mobile device may be transmitted, via multicast, to one or more other mobile devices. In one implementation, a method may include receiving, from a mobile device attached to a wireless network, a request to initiate a multicast transmission of content generated by the mobile device. The method may further include determining one or more wireless coverage areas to which the multicast transmission of the content is to be provided; receiving, from the mobile device, a unicast transmission of the content; and distributing the received content, via one or more multicast data channels that are broadcast in the one or more wireless coverage areas. |

1. A method comprising:
receiving, by one or more computing devices and from a mobile device attached to a wireless network, a request to initiate a multicast transmission of content generated by the mobile device; receiving, by the one or more computing devices and from the mobile device, information identifying other mobile devices that are intended to receive the content; receiving, by the one or more computing devices and from the mobile device, information identifying a particular geographic area, selected by a user of the mobile device, for distributing the multicast transmission of the content; determining, by the one or more computing devices, one or more wireless coverage areas, based on the particular geographic area, to which the multicast transmission of the content is to be provided, wherein the determining of the one or more wireless coverage areas to which the multicast transmission of the content is to be provided comprises:
determining a device identifier of the mobile device,identifying a user name corresponding to a user of the mobile device,determining followers associated with the user name,determining mobile devices associated with each of the followers, anddetermining the one or more wireless coverage areas based on physical locations, corresponding to the coverage areas, of the mobile devices; receiving, by the one or more computing devices and from the mobile device, a unicast transmission of the content, wherein the content provided by the mobile device is generated, by the mobile device, as video content; and distributing, by the one or more computing devices in real-time, the received video content, via one or more multicast data channels that are broadcast in the one or more wireless coverage areas such that the video content is only received by mobile devices that are identified as being intended to receive the content and that are located within the particular geographic area. |
