# 5 Comparisons

## 5.1 Introduction

In many situations, more than one technical solution is possible. It could be that none of them provides a completely ideal solution; each is likely to have its own merits and drawbacks, and often a compromise has to be made. This section is about comparisons. First we ask you to make a comparison between the two wireless technologies introduced in Section 4. This leads to a discussion about competing technologies and some of the issues that will influence the choice of technology for a particular application. We shall also ask you to make a comparison between different ways of presenting information. This leads to a discussion about the structure of a document and how this affects its readability.
