Critical Success Factors:Lessons Learned Challenges faced New product, new technology, and new company What was easier? Deployment, Management, and Support What was harder? WAN support, Outdoor coverage, Rogue AP Detection and Mitigation Things that went well Network Design, Application support, and Client access Things to avoid Complex Network Design (latency) Things you would have done different None What was unique about your experience? Large campus and older buildings Vendor role (+/-) Crucial involvement with vendor SE during initial phase of the project 17. Recommendations For other customers Identify Objectives Proof of Concept Test Applications and Network Design Controlled Pilot Deploy 18. Case Study Osaka Gas 19. Introduction Osaka Gas Japans 2nd largest utility company Distributes natural gas to 6.6 million customers, or about 25% of the total number of customers in Japan. Its service area covers 69 cities and 41 towns in six prefectures. 20. Problem Osaka Gas received industry-wide attention in 2005 with the announcement of its plan to install 6,000 wireless IP phones across its 49 offices. Vision: Create the ultimate address-free office environment with anytime, anywhere access via wireless laptops and telephones Change Our Work Style technology initiative Become the largest voice and data fixed mobile convergence solution 21.
