DASH7 Alliance Announces Updated Standard For Wireless Sensor Networks

San Ramon, CA, USA – July 20, 2010. The DASH7 Alliance (http://www.dash7.org), 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.

De-Mystifying Smart Grid Standards - Common Information Model (CIM)

"The “De-mystifying Smart Grid Standards” series started by reviewing new networking specifications - IEEE 802.15.4g, 15.4e, RoLL - part of the end-to-end Smart Grid communications architecture. The adoption of a TCP/IP-based framework for network communications enables Smart Grid applications to develop independently of the lower layers’ evolution and to leverage the standards-based two-way communications capabilities for important benefits such as:
  • Load control
  • Dynamic pricing
  • Outage detection
  • Distributed energy resource (DER) control signals
  • On-demand read
But TCP/IP does not address the challenges of data representation and exchange within and between Distribution Management Systems such as these Smart Grid domain/sub-domain examples:
  • Customer domains
    • Business/building Area Networks (BAN)
    • Home Area Networks (HAN)
    • Industrial Area Networks (IAN)
  • Operation domains
    • Monitoring
    • Control
    • Fault management"
