Method and system consist of a mobile application installed on a mobile device with internet connection and a geographical positioning device; a remote hosting server configured with software and database; an onsite wireless communication hosting apparatus. The mobile application communicates with the remote hosting server and the onsite wireless communication apparatus. The remote hosting server and onsite wireless communication apparatus communicate and transfer data to one another, the remote hosting server communicates with third party databases via secured access and retrieves location related information requested by onsite users of the mobile device. Web users at anywhere may select a location displayed on a digital map over interface of a web application configured to the remote hosting server; access the same as onsite users; including data entered by location owners, received from third-party databases via secured connection, and uploaded from onsite wireless communication apparatus.

According to some embodiments, a method includes selecting a length for an advanced television system committee (ATSC) 3.0 frame for transmission by a single frequency network (SFN) transmitter and aligning the SFN transmitter with a global positioning system (GPS) epoch. The method further includes storing geographical coordinates of the SFN transmitter and a corresponding SFN transmitter identification (TX ID) in a database. The method also includes encoding the SFN TX ID in a non-coherent symbol of a plurality of positioning navigation timing (PNT) symbols comprising a plurality of coherent symbols and the non-coherent symbol with orthogonal frequency-division multiplexing (OFDM) numerology to support positioning. The method further includes prepending the plurality of PNT symbols to the ATSC 3.0 frame to generate a modified ATSC 3.0 frame and transmitting the modified ATSC 3.0 using a SFN transmitter antenna of the SFN transmitter.

Disclosed example people monitoring methods include detecting a first watermark in a first audio signal obtained from an acoustic sensor, the first watermark identifying media presented by a monitored media device, determining whether a second watermark, different from the first watermark, is embedded in the first audio signal obtained from the acoustic sensor, the second watermark identifying at least one of a mobile device or a user of the mobile device, classifying the second watermark as a media watermark or a people monitoring watermark based on a characteristic of the second watermark, and when the second watermark is determined to be embedded in the first audio signal, reporting at least one of the second watermark or information decoded from the second watermark to identify at least one of the mobile device or the user of the mobile device as being exposed to the media presented by the monitored media device.

An example apparatus to monitor media that is presented via a mobile device includes: an application monitor to determine when media presentation software is being executed by the mobile device; and a metering information collector to collect at least one of a signature or a code of the media presented by the media presentation software based on the media presentation software being executed by the mobile device.

Methods and apparatus to calibrate media ratings based on return path data are disclosed. An apparatus includes a processor and memory including instructions that, when executed, cause the processor to: determine an initial rating for the media provided in a first geographic area based on return path data (RPD) tuning information obtained from RPD devices in subscriber households in the first geographic area; determine a first panelist rating for the media provided in a second geographic area based on first panel tuning information obtained from first metering devices in a first subset of panelist households in the second geographic area; determine a nonsubscriber calibration factor based on the first panelist rating; and determine a final rating for the media in the first geographic area by modifying the initial rating based on the nonsubscriber calibration factor.

An example apparatus includes a meter to generate first information indicative of a media presentation mode of a media presentation application executed by a wireless communication device during a presentation of the media content received and presented via the wireless communication device, the media content comprising scheduled programming that is broadcasted or multicasted simultaneously to a plurality of other wireless communication devices during a pre-scheduled time; and generate second information indicative of the media content presented via the wireless communication device. A memory is to store the first information in association with the second information in the wireless communication device; and store third information in association with the first and second information. The third information is indicative of at least one of a location of a cell tower used to transmit the media content, an identifier of the cell tower, or an identifier of a wireless network access point.

A method is disclosed comprising: scanning for one or more signals sent by one or more beacon devices, wherein each signal of the one or more signals comprises an identifier of the beacon device, which has sent the signal of the one or more signals, wherein one or more identifiers of the one or more beacon devices are determined based on the one or more signals of the one or more beacon devices; obtaining a position information representing the position of the at least one first apparatus; and outputting a report information comprising the determined one or more identifiers of the one or more beacon devices and the position information of the at least one first apparatus to allow usage of the outputted report information to determine the position of at least one of the one or more beacon devices. A corresponding apparatus, computer program and system are also provided.
