ZMD AG announces the ZWIR4512, a low-power wireless data communication module for sensors, and other small devices used in industry and building automation, health monitoring, smart metering and keyless entry systems.

The ZWIR4512 provides communication for scalable networks by integrating a 32-bit ARM Cortex M3 processor with a complete communications software solution and an integrated radio. The radio operates in the 868/915MHz frequency band.

Networks built with the ZWIR4512 can connect directly to existing networks without the requirement for custom programmed gateways. This makes it easy to extend networking to applications previously too difficult or expensive. Designers can run their application software directly on the modules. Different low power modes help to save energy in battery-operated devices. The complete ZWIR4512 module measures 28 by 16.5 by 3.5 mm, including the antenna connector. It consumes 3.5 µA in sleep mode, and 18.5 mA when transmitting data at 0dBm output power.

Communication is based on IPv6, the next-generation Internet protocol. 6LoWPAN is used to optimize IPv6 packets for embedded low-power device networks. Data encryption and authentication is provided by the Internet Protocol Security (IPSec) protocol suite. IPSec keys can be exchanged and renewed automatically based on the Internet Key Exchange version 2 (IKEv2) protocol. IPSec and IKEv2 enable secure end-to-end communication, thus providing the same security level as virtual private networks. IPv6, 6LoWPAN, IPSec, and IKEv2 are all open standards developed by the IETF.

ZWIR4512 firmware offers a command interface and a C-language Applications Programming Interface (API). Pre-programmed units are also available. Modules and Development Kits are available today.
