Realtek_WPS_user_guide; RTK无线WPS操作手册 1. Introduction 1.1 Purpose This document describes supported WPS features of the series of Realtek 8xxx-SOC, the instructions of setting up a Wi-Fi network for different scenarios, and the recommended system configuration. 1.2 Scope This document is aimed to the engineers who have basic knowledge about WPS and will utilize Realtek 8xxx-SDK to develop their products. 1.3 Definitions of Wi-Fi Protected Setup terminologies (Wi-Fi Protected Setup Specification 1.0h.pdf, p. 11) WPS: Stands for Wi-Fi Protected Setup; an optional certification program designed to ease set up of security-enabled Wi-Fi networks in the home and small office environment. Device: An independent physical or logical entity capable of communicating with other Devices across a LAN or WLAN. Domain: A set of one or more Devices governed by a common authority for the purpose of gaining access to one or more WLANs. Enrollee: A Device seeking to join a WLAN Domain. Once an Enrollee obtains a valid credential, it becomes a Member. In-band: Data transfer using the WLAN communication channel. Out-of-band: Data transfer using a communication channel other than the WLAN Member: A WLAN Device possessing Domain credentials. Registration Protocol: A Registration Protocol is a (logically) three party in-band protocol to assign a Credential to the Enrollee. The protocol operates between the Enrollee and the Registrar and may receive support through a proxy. In this document, it is equivalent to “WPS handshake”. Registrar: An entity with the authority to issue and revoke Domain Credentials. A registrar may be integrated into an AP, or it may be separate from the AP. A registrar may not have WLAN capability. A given Domain may have multiple registrars. External Registrar: A registrar for an AP’s Domain that runs on a device separate
