UMTS info

An introduction, listing the most common European mobile network technologies.
Klaas van Gend also held a presentation on UMTS at the NLUUG. Paper and slides are available.

Otherwise, for now, I'm going to point to two other sites with a vast amount of information:

• Wikipedia page on UMTS
  vast amounts of information on UMTS in general
• PHARscape
  Paul Hardwick's site on how to use Option cards with Linux
