This Standard specifies the minimum requirements for media and
\nprotocol-specific call control interoperability, acoustic
\nperformance, telephony feature support, safety, electromagnetic
\ncompatibility, and environmental performance of WLAN IP telephony
\nendpoints operating in a business environment<\/p>\n
Since WLAN are normally used for mobile devices, the
\nspecification is normally for such mobile device operated by
\nbattery power. However, non-mobile telephony endpoints using WLAN
\nfor connection are within the scope of this specification. In fact,
\nalthough this Standard specifically addresses physical IP phones,
\nit does not preclude the implementation of applicable functionality
\nin a soft client. However, such soft implementations are not
\nspecifically addressed in this Standard.<\/p>\n
This Standard applies specifically to WLAN IP telephony
\nendpoints that are interfaced to the Wireless LANs. Due to the huge
\ngrowth of products certified by Wi-Fi Alliance on the market, this
\npresent standard is focusing today on the IEEE 802.11 standards.
\nSince many new specifications are in progress within the IEEE
\n802.11 working groups in terms of security, QoS, and mobility, this
\ndocument may require updates whenever a new IEEE 802.11 standard is
\napproved or a Wi-Fi Alliance Certification program becomes
\navailable. Also, these interoperability requirements should be
\napplied to both 802.11b\/g (2.4GHz band) and 802.11a (5GHz band),
\nbut need to be checked in terms of end-to-end performance.<\/p>\n
This Standard defines a "VoWLAN profile" in the corporate
\nenvironment. The specification for the roaming and handover
\nrequirements between different environments (home, public,
\ncorporate) is for further study. Also, this document does not
\naddress phones in a residential and public access WLAN
\nenvironment.<\/p>\n
This Standard harmonizes, wherever possible, with Megaco
\nprotocol as applicable to control of IP telephones.<\/p>\n
This Standard supports the use of ITU-T Recommendation H.323
\nprocedures for call establishment and call control.<\/p>\n
This Standard supports the use of the Session Initiation
\nProtocol (SIP) for call establishment and call control.<\/p>\n
Note: The choice of implementing H.323 or SIP or Megaco is up to
\nthe manufacturer.<\/p>\n
This Standard does not place requirements on system level
\ncomponents such as call agents, proxy servers, gateways or
\ngatekeepers or Wireless LAN infrastructure.<\/p>\n
This Standard specifies security requirements pertaining to the
\nprovisioning of a WLAN IP telephony endpoint, but leaves the
\nprovisioning implementation itself up to the discretion of the
\nmanufacturer.<\/p>\n","protected":false},"excerpt":{"rendered":"
