14.1 Reconfigurable Elements
The classical approach for solving the various air interface standard problem has been that manufacturers were forced to produce their own legacy implementation of a radio platform. However, applying this rigid approach to software radios would lead to very restrictive software defined platforms that would merely allow the reconfiguration using manufacturer verified software. Such a legacy approach is a contradiction to an open platform and would deny the user the advantages of the origin al Software Defined Radio (SDR) ideas [1]. Instead, such a manufacturer-specific approach would result in numerous different radio processing platforms, each following a different modularisation approach. In addition, reconfiguration software would be product-specific instead of being generally useable.
Preceding chapters in this book have described the requirements for reconfigurable systems looking from the user, manufacturer, and operator viewpoints; they also outlined the functionality to be provided by networks to support reconfigurable terminals. But one may ask: What are the effects of reconfigurability on mobile networks? Which levels of the network are affected by reconfigurability? And how can reconfigurability be cast into a framework without limiting the degree of freedom it offers in the first place?
Reconfigurability influences all levels within a communication ...
