DASH7

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.868/915 MHz: +27dBm166.667 kbit/s / 9.6 kbit/s, 55.55 kbit/s or166.667 kbit/sTreeRegulations (from 1 mW to 1 W)Aggregation), up to65,535 Bytes (withAggregation)per Sector (Assumes 8channel Access Point)/AP aggregates to 156 kbit/sper Sector (Assumes 8channel Access Point)supported with an RPMAextendertypicalUS:<+27dBmUS:900bit/s-100kbit/s/900bit/s-100kbit/s30 km (rural)20 byte payload10 km (urban),1000 km LoSmessages/day/max. 4 messages of 8bytes/day10 Mbit/s/1 kbit/s to10 Mbit/s100 kbit/s/200 bit/s to100 kbit/s 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.

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.
