dresden elektronik ingenieurtechnik gmbh
Your Partner for electronics development, production and testing

We have been developing and manufacturing industrial electronics since 1990. According to our principle that there is a solution for every problem, we offer complete solutions including the development, prototyping and series production. Using our inhouse test laboratory a broad spectrum of EMC testing, electrical, climatic and optical examinations can be carried out.

Wireless Communication:
"From flexible product development to stable production runs"

This is the challenge of our company and the main focus of the range of Wireless Communication as well. As full-line provider we offer development of hardware and software, prototyping, type testing and serial production.

Expertise
We focus on short range networks in our activities in the range of wireless technologies. National 868 / 915 MHz and international 2,4 GHz frequency bands are supported. We use different chip sets of different manufacturers. According to the respective requirements both ceramic and circuit board antennas are used. We utilise product-specific, customized and standard antennas.



Hardware and Software development
The experiences of our engineers cover simple Peer-to-Peer applications as well as complex networks. In every development phase the communication to our customers is important for us. Our advantage is the close collaboration of the engineering department with manufacturing area. This enables us to create high quality products and comprehensive documents for manufacturing and service.

Production and Testing
We have established the complete product creation chain starting with product design followed by prototyping, testing, verification and serial production. Our production area has the capability to handle more than 250.000 components per day. All the electrical parameters and the performance of radio communication of our products are tested in the in-house test area. Our own engineering department "Test Systems" provides best solutions for the required test equipment.

Perfect solutions

Radio networks offer the full comfort of wireless connectivity, expensive cable installations are no longer needed. The wireless network must be easy to install, has to assure a robust and reliable communication and the separate nodes have to work battery driven over years. We prefer solutions for low-cost and low-power embedded applications in comparison with other existing radio technologies.

LR-WPANs (Low Rate Wireless Personal Area Network )
These networks are developed especially for sensors and actuators and have the ability of self-configuration, redundancy in the transmission line and they realize the extension of the transmission range through multi-hops. Data rates are between 20 and 250 kbit/s. To allow coexistence with other wireless technologies, CSMA/CA for collision avoidance is consistently used.

ZigBee Standard

Using the ZigBee standard these advantages can be realized with low data volume. The devices have a low current consumption. With two batteries type AAA a radio node reaches an operational period of several years. Typical ranges of a single ZigBee-node are 20 to 50 m within buildings.

Proprietary

Suitable proprietary solutions can be used, if the existing standards do not meet the requirements.
