Abstract
This disclosure relates to relating time-to-live information with location data for wireless network access points. A freshness component determines a value associated with a freshness of location data for an access point. An encoding component encodes the value into a time-to-live information element included publicly broadcast access point information, and a transmitter transmits the publicly broadcast access point information. The publicly broadcast access point information includes at least one of a beacon frame or probe response. Additionally, by providing a value satisfying a non-inclusion threshold for the time-to-live information, emitters or network administrations may use time-to-live information to indicate that they do not wish to have location data for an access point stored.
