ISO/IEC 29341-8-21:2008

Overview

ISO/IEC 29341-8-21:2008 - "Information technology - UPnP Device Architecture - Part 8-21: Internet Gateway Device Control Protocol - Wireless Local Area Network Configuration Service" - defines a UPnP-based service model for controlling, monitoring and configuring IEEE 802.11 wireless access points in unmanaged networks (homes, small offices and public spaces). The standard specifies state variables, actions and eventing for common WLAN configuration tasks: setting SSID, channels, security settings and radio modes, plus diagnostics and location information. It is part of the broader ISO/IEC 29341 UPnP Device Architecture series that enables peer-to-peer connectivity among appliances, PCs and wireless devices.

Key topics and technical requirements

• Service modelling and XML description: formal UPnP service type, state variables and XML service description to ensure device–control point interoperability.
• State variables and monitoring: examples include SSID, BSSID, BeaconType, RadioEnabled, RegulatoryDomain, Channel, ChannelsInUse, transmit rates, and association statistics (TotalBytesSent/Received, TotalPacketsSent/Received).
• Security and keys: management of wireless security elements such as WEP keys, PreSharedKey (PSK), WPA/IEEE 802.11i-related authentication and encryption modes.
• Control actions: concrete actions for runtime control - e.g., SetSSID / GetSSID, SetChannel / GetChannelInfo, SetRadioMode / GetRadioMode, SetSecurityKeys / GetSecurityKeys, factory reset and authentication resets.
• Eventing and moderation: event notification model and moderation parameters for subscription-based updates to control points.
• Diagnostics and operation: failure status, per-device association info, byte/packet statistics, and operational mode management.
• Testability: test procedures and XML-based service description to validate device compliance.

Practical applications

• Firmware development for home routers, wireless access points and gateways implementing UPnP control for WLAN setup.
• Control point (client) software that automates network configuration, diagnostics and monitoring in residential and small office (SOHO) environments.
• Integration into smart home and IoT ecosystems to enable plug-and-play wireless configuration.
• Certification and interoperability testing by compliance labs to ensure consistent UPnP behavior across devices.

Who should use this standard

• Router and access point manufacturers, embedded firmware engineers, UPnP stack developers, network integrators, IoT platform vendors, and test laboratories focused on wireless device interoperability and automated network configuration.

Related standards

• ISO/IEC 29341 series (UPnP Device Architecture)
• UPnP Forum specifications and IEEE 802.11 (wireless LAN) standards
