While Bluetooth is wide spread in wireless applications today a new radio technology called ZigBee comes up to the market. Though ZigBee tends not the same market segment like Bluetooth it competes with Bluetooth in several applications. The initial market for ZigBee, defined by the promoting organization, the ZigBee Alliance, is the wireless automation of home, building and industrial applications. But so called personal area networks with low data rates (LR-WPAN) would be as well a field of application for this upcoming radio technology. The fast growing market for wireless technologies such as wireless LAN or Bluetooth - even in medical environments-show the need for smart solutions as a cable replacement for patient sensors as well as for the infrastructure of clinical information systems that offer great advantages for both, patient and clinical personal in everyday life. Furthermore the network capabilities of ZigBee provide more functionalities especially for the field of medical body area networks. Due to lower power consumption this new radio technology offers longer run time for battery powered mobile and autonomous sensor devices. This research evaluates radio technologies for low power sensor networks and compares the use of Bluetooth and ZigBee in medical body area networks. For these composition proceedings a multi sensor network based on ZigBee technology was developed to examine the advantages and disadvantages of each technology.
