EditorialEric PetersonSince joining the staff of Ericsson Review in1997, numerous articles on a variety of topicshave passed across my desk. We (the publisher,editorial board and myself) are fairlyselective when choosing articles for publication,so I assume that every article inEricsson Review is of interest to our industry.But obviously, some articles also hold a specialpersonal interest to me as an end-user.That is, given the insights I have gainedfrom reading and preparing articles for publicationin Ericsson Review, I have eagerlylooked forward to the day when I would seereal consumer services and products basedon, say, Bluetooth, xDSL, WLAN, GPRS,SyncML, GPS and more. Two years ago, Ipredicted that that day would come beforeyear's end 2001. A year later, however, I hadto eat my words—if you weren't (a) an earlyadopter or (b) actively looking for it, thenyou probably hadn't noticed anything thateven remotely resembled what we call theMobile Internet. But today that's allchanged. The Mobile Internet is all aroundus and is fast becoming an integral part ofordinary people's lifestyles.We often read about or hear that the industryis in a slump. Well, it is. But don't tellthe end-users! Given all that has happenedon the consumer/end-user side of things—the advent of some really great mobile terminals,and a maturing of standards, servicesand applications—I am convinced that theworld of mobile telecommunications hasnever been more exciting. Face it, the averageend-user cares nothing for the actualtechnology in use—all he or she really wantsare hassle-free services.In my own case, the single largest factor propellingme toward a richer Mobile Internetexperience was the switch to a new handset—inFebruary, I traded my trustyEricsson R380s for a Sony Ericsson P800.Today, I enjoy e-mail and Web-based servicesvia GPRS, I frequently use Bluetoothfor transferring fdes between my phone andlaptop, and thanks to remote-synchronizationservices, I can keep my contact and calendarinformation up-to-date on multipledevices. Hey, as an end-user, I'm in serviceheaven! And the best part of all is that I knowthis is just the beginning—better, more potentand really useful services are on the way.In this issue of Ericsson Review you can read,among other things, how the industry,through the Open Mobile Alliance, is takingsteps to make services interoperable.You will also read about Ericsson's servicenetwork framework, which provides architecturalprinciples for creating horizontallylayered service networks. Furthermore, youcan read how Ericsson is prepared to helpoperators to realize the true potential of theservice network and move toward fullythird-generation-ready networks. Like Isaid, better, more potent and really usefulservices are on the way!Eric PetersonEditorEricsson Review No. 1, 2003
