It is basically standard RFID open source used for WSN (Wireless Sensor Networking). It operates in frequency band of 433MHz. Dash7 technology is promoted by the DASH7 Alliance. This technology provides a long battery life and a coverage of about 2 km indoors.
The DASH7 (D7A) alliance protocol is an open source wireless sensor and actuator network protocol operating in the unlicensed ISM / SRD band of 433 MHz, 868 MHz and 915 MHz. DASH7 offers a battery life of several years , A range of up to 2 km, low latency to connect to mobile elements, a very small open-protocol protocol stack, 128-bit AES 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 DASH7 Alliance.
DASH7 Alliance Protocol comes from the ISO / IEC 18000-7 standard that describes a 433 MHz ISM band interface for active RFID. This standard was mainly used for military logistics.
The DASH7 Alliance redesigned the original 18000-7 technology in 2011 and evolved it into a wireless sensor network technology for commercial applications. The DASH7 Alliance Protocol covers all Sub-GHz ISM bands that make it available worldwide. The name of the new protocol was derived from section seven denoted as -7 (/ 'dæʃ' sevən /) of the original standard document.
The current version of the DASH7 Alliance protocol is no longer compatible with the ISO / IEC 18000-7 standard.
