9 Location and device transfer Payment model Security Malicious use User identification Location identification Other technology issues Other technology issues: Location and device transfer Location-to-location and device-to-device transfer must not result in break in service Question: How can mobile systems provide capabilities for users to move between locations and devices without losing continuous services? Issue: Need for seamless transfer between locations and devices 9

10 Other technology issues: Payment model Different payment model for mobile device communication than for wired device communication because of device limitations Limited screen => Web advertising may not work Some methods of charging for wireless connection: Monthly subscription Per minute/per use charge Combination Question: What are the best ways to charge for wireless communication links? Issue: Method of charging for wireless connection Other technology issues: Security Wireless communication is easy to intercept Frequency hopping and encryption help but do not solve problem Question: How can users and organizations be assured that data is secure when transmitted over wireless networks? Issue: Security of data traveling over wireless networks 10

11 Other technology issues: Malicious use Viruses are potentially greater problem with mobile devices than with wired networks because of difficulty to control Hacker can use stolen device, then destroy device to avoid detection Question: Can technology that minimizes the impact of viruses on wireless devices and networks be provided? Issue: Virus management Other technology issues: User identification User identification is important to validate transactions Question: How can users be positively identified without undue intrusion on their time and privacy?
