Wireless technology, with its ability to increase system flexibility and mobility, has become an integral part of many embedded and consumer applications. Even a simple RF system, however, introduces many critical design issues with a fair number of tradeoffs. This article explores how to optimize RF design for critical data transfer applications and power critical data transfer applications. In this regard, the best methodologies for designing optimized systems are based on parameters including power consumption, delay, throughput, quality of service, security, robustness to noise, development complexity, difficulty in integration, and cost. Most of these issues are application dependent.
