DASH7 Alliance Protocol (D7A) is an open source Wireless Sensor and Actuator Network protocol, which operates in the 433 MHz, 868 MHz and 915 MHz unlicensed ISM band/SRD band. DASH7 provides multi-year battery life, range of up to 2 km, low latency for connecting with moving things, a very small open source protocol stack, AES 128-bit shared key encryption support, and data transfer of up to 167 kbit/s. The DASH7 Alliance Protocol is the name of the technology promoted by the non-profit consortium called the DASH7 Alliance.
DASH7 Alliance Protocol originates from the ISO/IEC 18000-7 standard describing a 433 MHz ISM band air interface for active RFID. This standard was mainly used for military logistics.
The DASH7 Alliance re-purposed the original 18000-7 technology in 2011 and made it evolve toward a wireless sensor network technology for commercial applications. The DASH7 Alliance Protocol covers all Sub-GHz ISM bands making it available globally. The name of the new protocol was derived from the section seven denoted as -7 (/dæʃ ˈsɛvən/) of the original standard document.
The current version of the DASH7 Alliance protocol is no more compliant with the ISO/IEC 18000-7 standard.
