  1. INFOTECH Seminar Advanced Communication Services SS 2003 Applications developed with J2ME MIDP 1.0 & 2.0 June 27, 2003 Yun Guo

  2. Traditional Telecommunication Networks Software New Mobile Telecommunication Networks: Download Software What is new about Applications for Mobile Phones? Mobile set can load new application software

  3. What is the difference between applications installed by the manufacturer of the mobile and applications, which may be loaded by the user? How dangerous is loading of applications? How do telecommunication services look from the perspective of a developer and what kind of services can be developed? What is behind J2ME as a technology for such services? Questions
