In collaboration with Carlstedt Research & Technology AB and
Eritel AB, we developed a prototyping tool for testing and
modelling communication protocols in the mobile data network
Mobitex. A screen dump of the tool is found in Figure 97, and
shows a configuration with three radio base stations, each which
covers a triangular area. The small circular objects are mobile
users. Roaming of the users between
base station areas is simulated using the drag-and-drop feature
from Chapter 25.
