Abstract
Already for quite some time efforts in the industry are ongoing to attain standardization for wireless communication in radio nets of small range (WPANs - wireless personal area networks). Target markets here are for example house automation, sensor networks or industrial data communication.
IEEE 802.15.4® is a standard for short range wireless communication and has been ratified by the “Institute of the Electrical and Electronics Engineers” of the USA in May 2003. In this standard the physical characteristics of a radio interface (frequency bands, data rates, modulation procedures, frequency spreading) are defined.
The next higher level sitting on top of the PHY is the MAC (Media Access Control) layer. It defines how the radio interface is to be accessed. The two layers MAC and PHY are defined by the IEEE 802.15.4 standard and are described in a work of more than 600 pages, which can be downloaded from the internet.
Based on the IEEE 802.15.4 standard several technologies for Wireless Sensor Networks have been defined. Examples for these technologies are ZigBee, ZigBeePro and 6LoWPAN. In the industrial space, technologies like WirelessHART and ISA100.11a are winning recognition.
