MMS-C Multimedia Messaging Center

Back in 2002-2003, I was involved in several Multimedia Messaging Service Center (MMS-C) system integration projects for Ericsson, introducing MMS to the German mobile telecommunications market. This work included integrating the first mobile phones that supported MMS, such as the Ericsson T68 and Nokia 7650.

In addition to setting up MMS-C infrastructure for German telecom providers, I also developed a few showcases for the Cebit fair, including web/WAP content portals for MMS and an Over-the-Air (OTA) configuration system that automatically set up WAP and MMS settings on mobile phones.

Projects also included setting up the Ericsson Multimedia Library (MML) system, a content portal providing images and sounds for use in MMS.

It was a lot of fun and a great experience! MMS was quite expensive in Germany back then, so may it rest in peace forever ;)

Wireless Banking

Developed one of the first mobile WAP (Wireless Application Protocol) banking applications for a Bavarian bank, offering stock market information. It supported proper rendering of markup across leading mobile phones of the time, including Nokia, Ericsson (such as the R380, the first Symbian OS phone), and Siemens.

Worked on Mobile Digital Signature for Wireless Banking involving Ericsson Wireless Wallet Prototype (a portable smartcard reader with built-in Bluetooth) and a special version of Ericsson R520m “Tiger Stripe” with adapted firmware. Showcased wireless signing of banking transactions using smartcard at Cebit Hannover.
