The demand for ad-hoc networks, personal area networks (PANs) and Body Area Networks is growing exponentially. A PAN is defined as a computer network used for communication among computer devices close to one person. Somewhat closer to a person a Body Area Network (BAN) can be defined. A BAN consists of a set of mobile and compact intercommunicating sensors, wearable, implanted, or even ingestible into the human body, monitoring vital body parameters and movements. These wireless technologies for short range access have been embedded in millions of commercial devices already. Examples of available standards are Bluetooth, Zigbee, and Wibree (recently renamed as Ultra-low-power Bluetooth). The main issues in this research area (which we call Short-Range Radio - SRR) are low power consumption, robustness to interference, integration on chip (including the antenna) and overall costs.
