  1. A Wireless Internet 101 Presented at CommunicAsia 20th June 2001 Immo Hüneke Technical Architect, Wireless Internet

  2. What is the Internet? • The Web and more… • Personal Communication(e-mail, instant messaging…) • Source of Information • Provider of Entertainment • Personal Soapbox • Medium for Advertising and Promotions • A Place to do Business • Standards Based • Seamless • Global A Wireless Internet 101

  3. Is the wireless Internet a hoax? • Why WAP didn’t overwhelm the world • Slow to connect (via GSM Circuit-Switched Data – CSD) • Slow to load pages • Limited display capabilities • No sound or colour • Lack of standardisation leading to many unusable sites • Lock-in by operators (“walled gardens”) • Nevertheless, useful services exist • …just as long as you don’t expect them to resemble the wired Web surfing experience! A Wireless Internet 101

  4. Wireless Internet USP • The Unique Selling Propositions of the wireless Internet • Ubiquity • Immediacy • Location sensitivity • Personalisation • One-on-one medium • Mobile device is virtually an extension of the individual • Ideal for highly targeted marketing and mobile commerce • So – how is it going to be done? A Wireless Internet 101

  11. Types of mobile data device • Laptop PC • Personal Digital Assistant (PDA) • Mobile Phone • Pager • Wearable • Dedicated (e.g. vehicle tracker) A Wireless Internet 101

  12. Challenges • Special challenges that have to be overcome to deliver the wireless USP: • Issues for Consumers • Issues for Corporates • Issues for Service Providers • Issues for Content Providers • Issues for Network Providers • Issues for Regulators (not considered further here) A Wireless Internet 101

  13. Issues for Consumers and Corporates • Cost and usefulness of service • Convenience • Handset usability, battery life • Ease of use • Reliability, coverage • Quality of service • Security! • Convenient billing and payment • Lifestyle A Wireless Internet 101

  14. Issues for Service Providers and Network Operators • Business models • Payment options • Usage metering • How to maximise ARPU • Service levels • Managing service evolution • Disintermediation and re-intermediation: the provider tangle • How can we trust each other A Wireless Internet 101

  15. The need to use tariff models to deter wasteful usage Huge telco profits lead to impoverished users, particularly among the under-25 age group, which leads to political regulation Telcos find it hard to profit from packet transport, so moving to charging for content, services, and mobile commerce Carving out a niche in micro-payment banking services (consumers need banking services, but not necessarily banks) Technology Changes Business Rules A Wireless Internet 101

  16. Key messages Things to bear in mind during the remaining presentations: • Keep it real • Maximise return on investment • Concentrate on end-to-end solutions A Wireless Internet 101

  22. GSM provides PPP over CSD – pick your own ISP! Packet Datagram Protocol (PDP) on air-side IP protocols, SMS and X.25 “tunnel” through GPRS backbone network (which is itself IP based) WAP is an application-level protocol like HTTP: it can be used over GSM data calls, GPRS, UMTS… But other protocols may be more appropriate, particularly at higher bit rates (GPRS, EDGE, UMTS, wCDMA) – BlueKite, i-mode... Ubiquitous availability of SMS and USSD may make these more attractive than WAP (WAP layered on these protocols is defined but not implemented) WAP, GPRS and alternatives A Wireless Internet 101

  23. Requirements for Application Development & Deployment “An extensible, unified, implementation infrastructure for Wireless Internet application development and deployment” Goals: • Support Rapid Application Development • Prototype, trial, deploy, customise • Content must be easy to publish • Tailored for the wireless environment • Extensible content format though XML • Delivery channel independence • Easy to add new target devices such as iMode and Interactive TV • Applications should be able to exploit device capabilities • Scalable, Portable, Managed A Wireless Internet 101
