In one aspect, the present disclosure may provide devices or systems configured to receive indications of geographic areas, each corresponding to distribution networks, and determine whether the distribution networks overlap. The processor(s) may also be configured to receive parameter value(s) obtained by a device within one distribution network at a location within an overlapping area, and cause device(s) within another distribution network to modify operation based on the parameter value(s). In another aspect, the present disclosure may provide devices that include a voltage sensor to measure a voltage of a power distribution network at a power consumption location that corresponds to the device. The device may be configured to provide at least one cable service to the power consumption location via a cable television (CATV) distribution network and output an indication the measured voltage value.

Artificial-intelligence-based broadcasting. In an embodiment, a graphical user interface is generated comprising at least one broadcast screen. The at least one broadcast screen comprises one or more inputs for receiving a message, and receiving one or more criteria for determining one or more recipients of the message. In response to at least one user operation by a sending user within the at least one broadcast screen, provision of the message is initiated to one or more recipients who are determined based, at least in part, on the one or more criteria and artificial intelligence.

Geocast-based file transfer may be implemented via use of a Geocast File Transfer (GFT) protocol. A sending device may parse a file into multiple chunks. Respective multiple geocast packets comprising the chunks may be geocast. The sending device may geocast all packets sequentially. Upon geocasting all packets, the sending device may wait a predetermined amount of time. During the period of time, any receiving device that did not receive a chunk of the file may geocast a request for the missing chunk. Receiving devices also may wait various respective amounts of time before geocasting requests. Other receiving devices that may have missed a chunk may hear that the chunk it missed is being requested. And that device need not make a request for the chunk. Rather, that device may wait for the sending device to retransmit a geocast packet that contains the missing chunk.

The application discloses example methods and apparatuses for map generation and for playing broadcast signals. One example map generation method includes receiving multiple pieces of first information, where each piece of the multiple pieces of first information includes a corresponding positioning location of a corresponding terminal, strength of a broadcast signal modulated at a first modulation frequency and received by the corresponding terminal at the corresponding positioning location, and the first modulation frequency. A broadcast signal strength layer is generated according to the multiple pieces of first information, where the broadcast signal strength layer represents a first coverage range corresponding to a first strength range of a broadcast signal modulated at the first modulation frequency.
