Embedded wireless control and alarm systems based on DECT (Digital Enhanced Cordless Telecommunications)

In larger areas like factory plants, hospitals or office buildings there is a need to distribute mobile sensors or actuators for data acquisition, location determination or remote control. For reading or controlling these nodes a wireless transmission is preferred. Using existing DECT infrastrucure to realize this wireless control and alarm systems saves costs as DECT systems are widely used. Examples are residential phones at home or pico cellular networks in office buildings or public areas. Futhermore DECT offers high reliability as well as outstanding security features. The Fraunhofer Institute for Integrated Circuits IIS in Erlangen/Nuremberg has been working for many years on the field of wireless communication based on DECT. With the developed embedded DECT devices it is possible to realize wireless control and alarm systems which use existing DECT infrastructure.
