Fundamentals of Radio Control - Introduction

Radio software control requires understanding of RF systems at functional level. RF architecture and components vary depending on the target operation, the target performance, the cost. The target operation is most complicated factor that is a composition of can be split many sub-factors such as operation frequencies, operation mode, possible interferences in the operational environments, operation bandwidth. In today's cellular phones, more than one radio operation mode, and more than one operation frequency bands are supported. We call "multi-mode and multi-band" radio operation. The optimized RF architecture becomes more complicated, and therefore subject to more challenges in design and control.

In this sequel we give an overview of the fundamentals on:

• Functional Overview
• Architecture Overview
• Basic Elements
• Basics on RF software drivers
