Techniques are presented herein that support a close-proximity, ultrasound-based discovery and data exchange capability that provides a non-intrusive method for exchanging data (such as, for example, location information) between devices that share the same airspace. Using ultrasonic sound, information may be shared between any device capable of transmitting and/or receiving ultrasonic sound waves and elements of a network or building infrastructure allowing for the exchange of very specific and dynamic location data. One immediate use case for such technology is in the handling of emergency service (e.g., 911) calls where time and accuracy are critical. The presented techniques may find use in any number of other environments or scenarios including, for example, security and safety, an Internet of things (IoT) setting, a retail establishment, capacity planning, contact tracing, etc.
