2 Hotspot Critical Mass Usage per sub Critical Mass Subscribers Hotspots Achieving critical mass is essential to business success Hurdles to overcome 2003 Openwave Systems, Inc. All Rights Reserved 2

3 Hurdles in Achieving Critical Mass AP Range Access to Venues Venue Contracts Short range (100 ~ 500 ) Massive number of APs required to provide reasonable coverage Short range mandates APs to reside within a venue Access to venue is controlled by venue owner Establishing and managing contracts with venue owners is a complex task 2003 Openwave Systems, Inc.

7 Networks Components Access Points (AP) WLAN Access Gateways (WAG) Authentication, Authorization and Accounting (AAA) Wireless Proxy/Gateway Billing VPN Gateway Access point is a bridge that moves packets from the wired infrastructure and transmits and receives them over the air using standards based on IEEE protocol WLAN Access Gateways prevents unauthorized usage of the WLAN infrastructure AAA server provides centralized authentication services, authorizes usage of specific services and provides accounting records related to service usage Proxy/gateways prevents unauthorized usage of the mobile wireless data infrastructure. Provides filtering and translation of content and protocol based on device capabilities. Tracks usage of services generates billing Terminates VPN tunnel in side a secured network.

13 Managing the Dynamics using Roaming Profiles Roaming profiles reflect roaming agreements and associated settings Controls which system is selected and how to get authenticated When configured in a device, it enables devices to intelligently acquire a preferred WLAN/cellular service with little or no user interaction Roaming Profiles contain: List of partner WLAN/cellular networks Priority in which networks may be used when more than one network is available Login credentials for each network Special charge notifications for the each network List of network the device may not access 2003 Openwave Systems, Inc.
