4 Project objectives TARGET: development of A network platform seamlessly integrating wireless and wireline access technologies Mechanisms for transparent service discovery (intelligent service location mechanism), configuration & provision of context-aware services Mobile clients featuring positioning functionality & user profiling APPROACH: usage of industry standards Compatibility / Availability (save resources) Industry acceptance (secure exploitation) Rapid development / deployment of NOMAD products Goal: Transparent delivery of composite, context-aware services to mobile users

5 TAXI TAX I TAX I NOMAD Drivers Diverse access networks Separate devices for data & telecoms Separate services in each environment (vertical) Explosive Internet growth Internet Home WLAN Wirelined Outdoors UMTS/GSM Ad hoc Office Trend for multi-service client/server networks Demand for context aware services Mobility Mobility

6 The NOMAD Approach Platform integrating diverse access networks (IEEE a/b, 2G+/3G, etc) Transparent service discovery, configuration & seamless provision Context-aware services: Integration of User Profiling & Positioning technologies Provision of integrated services Off-the-shelf solutions perspective

7 Integrated Network Platform Global Roaming Integration of access networks Wireless and wire-line Optionally ad hoc networks Access Freedom Integration of data and telecoms Personal Mobility (between devices) Television Mobility Ethernet / ADSL GSM / UMTS Access Devices In-car facilities TAXI Mobility Switch between devices Mobility Mobile Phone WLAN / Ad-hoc Personal Computer

13 NOMAD Work so far Capture of system requirements via a structured user-centred methodology, including the definition and detailed study of different target user group needs (consumers & stakeholders). Production of comprehensive usage scenarios and a superset of technical features to be considered for the project s trial demonstrations. Extensive market survey, and identification of trends & opportunities for the NOMAD technology. Proposal for the business model to be adopted by NOMAD comprising of organisation alternatives, anticipated products and potential portfolio of services Initiation of the specification phase for the NOMAD components Targeted and continuous dissemination and awareness creation activities Successfully passed the 1st Project Review

14 User-centered requirements capturing Methodology Step 1, partners ideas in the TA, users and (interview supported) stakeholders analysis Step 4, to follow in WP2, 3 & 4 evaluate designs against user requirements understand and specify the context of use specify the user and organisational requirements Step 2, Interviews at CEBIT, Helsinski airport, review of recent studies of other projects meets requirements produce design solutions Step 3, The NOMAD vision work-shop, interviews with stakeholders to clarify aspects of business model

17 Market & Business modelling study Methodological approach Identification of exploitable results of NOMAD Questionnaires supported qualitative survey Desk-Study/Market Survey (UMTS Forum Reports and other sources) Review of Business Models for 3G and beyond 3G available in related literature. Work resulted in proposal for NOMAD business model
