2. Introduction
As the consumer demand for DAB and DMB digital radio sets accelerates, there is a need
for effective demonstration of these radios in typical retail environments, especially in regard
to advanced features such as data services, EPG, advanced PAD features and so on. Often,
sales floors are less than ideal for these demonstrations due to the nature of the building
construction and their location.
An inexpensive repeater system has been designed to allow a very low power DAB signal to
be relayed to the immediate area of the retail store that wishes to demonstrate the features
of portable DAB and DMB.
The power level used is approximately one thousand times lower than a typical cellular
phone.
Average system installation should take a similar time to a typical satellite dish installation
and requires a similar level of competence.
