STQ Workshop on QoS for VoIP, 8-9 June, 1999, Sophia Antipolis S Wireless and Mobility aspects Scope of WG7  The TIPHON wireless group shall work to ensure that the general VoIP architecture and protocols defined by TIPHON are well suitable or can be profiled towards use in wireless access IP networks.  The scope of the TIPHON wireless group is to identify the requirements for current and future Wireless access networks to support TIPHON scenarios for IP Telephony services and to identify the specific technical requirements for TIPHON networks to interwork with current and future wireless access networks. Identified requirements will be liaised to the relevant standards bodies responsible for these wireless technologies.  TIPHON will not specify any new wireless access technology/PLMN nor redefine existing wireless systems/PLMN or parts thereof. TIPHON can however initiate and stimulate standards work in this area by working on an architecture independent of any specific wireless access technology.  Furthermore TIPHON will investigate aspects of mobility in the context of TIPHON scenarios. Mobility and wireless access are different concepts. Wireless access can exist without mobility (e.g. WLL); mobility can exist without wireless access, however the two can also coexist.
