LPWAN compared to WirelessHART The concept of Industry 4.0 includes both Internet of Things (IoT) and local (short-range) networks. Adoption of wireless sensor network (WSN) technologies is driving growth for the industrial Internet of Things (IIoT). Short range systems make up for the majority of connected devices however, the long-range systems like LPWAN (Low Power […]
The Eclipse Foundation joins the DASH7 Alliance We are happy to welcome the Eclipse Foundation as a new member of the DASH7 Alliance. Due to multiple benefits for both organizations, a mutual membership was exchanged between the DASH7 Alliance and the Eclipse Foundation. Both organizations share a focus on community-driven innovation and values such as […]
Join our Virtual Meeting on May 12th 4-5.15 pm CET.
The DASH7 Alliance is a non-profit mutual benefit organization formed to foster the existence and the further development of the DASH7 protocol specification (based on ISO 18000-7). It is the intent of the Alliance to enhance the technology beyond its current capabilities and physical boundaries to enable security, automation and control systems for a multitude of environments.
DASH7 Alliance Protocol
The DASH7 Alliance Protocol (D7A) is an Open Standard for bi-directional, sub-Ghz medium range wireless communication tailored for ultra lower sensor-actuator applications using private networks. D7A stems from ISO 18000-7 for Active RFID and operates in the sub-GHz ISM bands. The protocol specification is free to use without any patent or licence requirements. You can freely download the latest D7A version 1.2 specifications from this website.
Sensors will securely report events and actuators can receive commands with a typical latency of 1 second while consuming only 30 uA on average. It’s local synchronisation and smart addressing features allow to upgrade thousands of sensors simultaneously, drastically reducing the upgrade time.
D7A fills the gap between the Short and the Large Area Networks. D7A excels in urban and industrial network installations connecting actuators and messaging applications (sensors, alarms, states) with ranges up to 500 m.
