Introduction
Mobile connectivity is becoming the trend. More and more people are using wireless devices like telephones, personal digital assistants and laptops. Those who want to go wireless, still want to be connected to the rest of the world, mainly through the Internet. In order to achieve this, there has to be a fast connection like cable today but without the cable of course.
The question that covers the content of this paper, is:
What are the current possibilities in the area of mobile internet and what will be possible in the nearby future?
In more detail, this paper discusses some of the possibilities to be connected to e.g. the Internet without all the traditional cables involved. What technologies do and do not support wireless transfer of data? Which technologies will better enable wireless transfer of data in the nearby future? These items will be discussed in chapter 2 and 3. All main technologies will pass the revue: GSM, GPRS, UMTS, EDGE, and Bluetooth.
A problem that immediately occurs is compatibility. Most Internetbased information is currently brought to to consumers through simple HTML pages. Since most wireless devices do not have a 15" to 21" screen, it will become a problem to show the information correctly on a portable device. There are a number of different protocols to handle this problem. The ones we discuss in chapter 4 of this paper are: WAP, STK, I-Mode and XML. However, since we also think it is very interesting to look at possible future applications, we discuss some of them in chapter 5.
Although this topic does not lend itself for a final conclusion, we will try to summarize / conclude our major findings in chapter 6.
