10. Page 10 SC-ALLIP-20000217-012 Why is MWIF Different? MWIF is Operator/Service Provider driven and will specifically address their needs & concerns Infrastructure Cost Implications Multi-vendor requirements Quick and independent service creation / deployment MWIF will bring together the mobile wireless and Internet players to enable early deployment of seamless, economic IP-based Mobile wireless network (cost savings) to ensure target wireless architecture is aligned with the Internet to establish co-operative efforts to jointly deploy feature-rich end services (enhanced revenues from IP-based applications) Target Industry Sectors include: Wireless Operators Internet Service Providers Internet Application & Content Developers Internet Infrastructure & Mobile Telephony Network Element Suppliers

11. Page 11 SC-ALLIP-20000217-012 The Mobile Wireless Internet Forum will: be Open to all operators, service providers and suppliers who have a desire to produce a global, common vision for an Internet-based mobile wireless network and related service capabilities Act as a driver that is complementary to the existing standards working groups and will provide a common voice of global operators Ensure that key regional and global standards groups address requirements that global operators see critical to early and economic deployment of IP-based mobile wireless network will be mobile technology neutral and not biased towards any particular standards
