Discovery of services between devices is provided prior to establishing a connection between devices, including wireless-enabled devices or devices that are communicatively coupled to wireless access points or other wireless communication devices. Discovering services prior to establishing a connection may facilitate finding a desired service. The services that may be discovered may be, for example, print services, camera services, PDA services or any other suitable services. Services may be discovered using 802.11, Bluetooth, UWB or any other suitable wireless technology. An information element is used to wirelessly convey information related to a service and/or information related to service discovery.

La recherche de services avant établissement d'une connexion peut faciliter la recherche d'un service désiré. Les services qui peuvent être recherchés peuvent être, par exemple, des services d'impression, des services de caméra, des services d'assistant numérique personnel ou tout autre service approprié. Les services peuvent être recherchés par 802.11, Bluetooth, UWB ou tout autre technologie hertzienne appropriée.
