The reality of the communications market-place is that cost and
appearance mean much more to the consumer than the technology inside. Mobile phones sell
on their style and talk time, rather than their receiver sensitivity
or bit error rate performance.
This is an important lesson for engineers to grasp, for although some mobile phones
are indeed much better technically than others, all are simply assumed by the customer to
work properly, and achieving technical excellence may not lead to excellent sales.
It is a difficult and challenging task to design a product that meets the expectations and
needs without over-engineering or under-engineering
and all the cost, timescale and reliability issues that follow. It is hoped that this book
will provide a good grasp of the design choices available to the digital communications
engineer, from which a correctly engineered product can be achieved.
