As an extension to the book, I here have collected some articles and other pieces that I beleive add value. The content in some of the older articles is also used in the book, while the newer ones contain things that I would have wanted to include in the book if I had written it today. It is not unlikely that some of that will be included in later revisions.

• Article: Enablers - The link between Terminals, Networks and Applications (Jan 07, 2002)

With many networks available from different operators, it is key that applications can run without having to worry too much about the underlying technology. Still, it becomes increasingly important for developers to be able to access the nice features of the networks, like charging and positioning, via interfaces. Application Enablers provide this capability.

• Article: What can we learn from Japan? (June 27, 2001)

In these days where many of us are waiting for the mobile Internet to really take off, it is tempting to take a look to our friends in Japan and see what they have done to be successful over there.

A small piece written by a journalist that found great interest in the book. Ericsson liked it and published it on their external site. There has been lots of publicity coming from this and  one of the reasons that the hosts of the June 2001 3GPP meeting used the book for their proceedings.

• Article: WAP, now and in the Future

These days it is very popular to bash WAP and doom it to eternal humiliation and demise. On top of that, there   are other buzzwords coming up, like GPRS and 3G, so why should anyone need WAP anymore. This article gives some reasons why WAP will remain important and it also shows the migration of mark-up languages in the next generation of WAP.         

• Article: Positioning, Where you want to be

  Everyone seems to agree that location based applications will be hugely important in the future. With the E-911 requirements in the US even more focus has been put on the area, and many companies are betting big on positioning. This article aims to clarify some of the issues around positioning and also explains the most common positioning technologies. Also, check out this guide to the MPC API.

• Article: GPRS, A Key step for the Mobile Internet

Since the traditional 2G cellular/mobile networks are circuit-switched, the packet-switching feature of GPRS is hugely important. For applications developers this might be an even bigger change than the upcoming 3G networks. This is a small introduction to GPRS and should be a good start for anyone interested in packet switched mobile networks.
