A nomadic user can be given ubiquitous access to remote information stores and computing services. However, the behavior of wireless links creates severe inconveniences within the traditional data communication paradigm. In this paper we give an overview of the problems related to wireless mobility. ...

By implication, implementing a new pan-European digital network meant that existing analogue mobile phone networks would eventually be turned off with their frequencies being re-allocated for GSM services. The UK Government, in response to EU Directive 87/372/EEC, had previously announced that the ...
In the early 1990s, digital 2G (second-generation) began their ascent, allowing for basic data services such as text messaging and email. 3G networks began spreading in the early 2000s, and with them, so too did the concept of mobile Internet. With a fast connection, you could surf the ...
