The Proximity Service Discovery Protocol is a Microsoft proprietary protocol that allows a client to discover services in its physical proximity, which is defined by the radio range. The purpose of the Proximity Service Discovery Protocol is to convey service discovery information, such as service advertisements, as part of Beacon frames. Access points (APs) and stations (STAs) that operate in ad hoc mode periodically broadcast beacon frames. The beacon frame can contain single or multiple proprietary information elements that carry discovery information pertaining to the services that the device offers.

A PSD IE is used to transmit compressed information provided by higher-level discovery protocols for the purpose of passive discovery. One such higher-level protocol used for discovery is the WS-Discovery protocol. Any protocol can be used for discovery.
