15. 3/26/2003Project Wireless Vietnam15 Testing Methods Perform radio link test §Signal Noise Ratio Stability §Measure effective radio capacity §Measure IP throughput §Measure Quality of Service

16. 3/26/2003Project Wireless Vietnam16 Remaining tasks §Implementation §Verification §Documentation §Training §Handover

17. 3/26/2003Project Wireless Vietnam17 Problems Internal l Different goals for different team members  Individual performance rather then teamwork l Culture differences  Different way of working l Communication problems  Misunderstanding

18. 3/26/2003Project Wireless Vietnam18 Problems (cont) External l Hierachical level at MoST  bureaucracy decisions are made beyond our influence and knowledge l Lack of trust and believe in us  loosing motivation l Budget approved too late  lack of time for testing equipment

19. 3/26/2003Project Wireless Vietnam19 Risks No access to highest point or stakeholder’s building and infrastructure Radio design has to be redone Project delay and goals may not be achieved Plan B: implementation only in test environment

20. 3/26/2003Project Wireless Vietnam20 Benefits §Learn about new wireless technologies §Theoretical and practical, hand-on experiences §Involved in an international project that goes beyond countries’ borders §Understanding different culture and way of working

21. 3/26/2003Project Wireless Vietnam21 Summary What are we doing? §Provide wireless broadband access in Hanoi Where are we now? §Wireless technologies survey §Implementation plan §Ordered equipment Where are we going? §Implementation of the two pilot sites §Documentation and Training for stakeholders and staff at MoST What are we expecting? §Learn about wireless technologies §Gaining international experience §Discover other cultures
