A new wireless sensor networking technology, DASH7 uses the ISO/IEC 18000-7 standard for active RFID. It operates in the 433 MHz unlicensed spectrum. DASH7 provides many advantages over other wireless technologies such as multi-year battery life, dynamic range of up to 2 Km (potentially farther) etc.DASH7 is the name of the technology promoted by the non-profit consortium called the DASH7 Alliance. DASH7 follows the ISO/IEC 18000-7 open standard for the license-free 433 MHz-ISM band air interface for wireless communications. 433 MHz was first reserved for military purpose but is now available for use worldwide. DASH7 networking technology was originally created for military use and is now being re-purposed for many commercial applications in place of wireless protocols like ZigBee or IEEE 802.15.4.
