The DASH7 Alliance, a non-profit industry consortium that promotes the use of the ISO 18000-7 standard for wireless sensor networking, today announced the release of an updated specification for the ISO 18000-7 standard for wireless sensor networking that enables tag-to-tag communications, improved location precision, over-the-air configuration, and higher data rates. The Mode 2 specification was submitted as a new work item to the ISO 18000-7 standards committee following approval by the DASH7 Alliance, which today includes more than 50 participants from 23 countries. The full Mode 2 spec is available today to DASH7 Alliance members and will be available to the public in ISO in mid-2011.
DASH7 Mode 2 enables new applications for both enterprise and consumer customers, including improved “real-time” locating capability for indoor asset tracking and access control, longer range communications for enabling smart billboards, and internet addressing for smart energy applications requiring IPv6. Mode 2’s improved support for public key encryption is essential for many consumer applications where privacy is a top concern. “DASH7 Mode 2 is an important specification for automotive applications like tire pressure monitoring but holds even more promise for non-automotive applications like smart buildings and mobile advertising,” said Dr. Patrick King, Global Electronics Strategist for Michelin Corporation. Utilizing a new multi-channel architecture and improved modulation and encoding techniques, DASH7 Mode 2 preserves the sub-16 kilobyte protocol stack size of DASH7 Mode 1 while making it easier to support public key encryption, IPv6 addressing, and sensor data. DASH7 Mode 2 devices can also be configured to include optional backwards compatibility with legacy Mode 1 devices. “By advancing specifications to ISO 18000-7 standards, DASH7 continues to position active RFID as an enabling technology for a wide range of solutions, applications and markets taking advantage of low-power, wireless sensor networks,” said ABI Research RFID Practice Director Michael Liard.
