Last month we welcomed Onesitu to the DASH7 Alliance, let’s look a bit closer at this interesting company and find out what the partnership brings for both parties. Onesitu is a provider of intelligent and connected solutions. Onesitu offers autonomous mobile solutions to revolutionize urban parking in cities of the future. They design and manufacture in France a […]
The DASH7 webinar of March 18th was centered arrpound Real time location systems (RTLS) and contained 2 parts, both parts are recorded. Research study on SDR (Software Defined Radio) by Noori Ben Lam from Antwerp – Imec – IDLAB Use case presentation on RTLS by Michael Andre from Wolt (powered by Wizzilab) To follow the […]
Low Power versus Ultra low Power, these are popular statements used by sensor manufacturers, it makes sense, as from various reports it becomes clear battery lifetime is the most important aspect when considering a sensor beside functionality of course. However, the type of wireless network has an enormous impact on the sensor power consumption, making […]

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.
