		DASH7 - A New Low Power Wireless Sensor Networking Technology DASH7 is a new wireless sensor networking technology that evolved from a combination of existing radio-frequency identification and sensing technologies.

DASH7 is a new wireless sensor networking technology that evolved from a combination of existing radio-frequency identification and sensing technologies. Products with DASH7 capability built-in or attached to them will dramatically simplify the way we keep in touch with the "non-human" world around us, improving the wireless communications capabilities of a wide range of mobile devices.

DASH7 Features:

   •   Operation at 433 MHz, globally available, unlicensed spectrum
   •   Based on ISO 18000-7 standard
   •   Multi-year battery life
   •   Range of up to 2 km
   •   Penetration of concrete walls, water, and ability to "bend" around metal objects
   •   Low latency protocol that enables reliable tracking of moving objects
   •   Small, lightweight protocol stack that minimizes silicon costs
   •   Data transfer at up to 27.77kpbs (potentially as high as 250kpbs)
   •   Sensor&security support

Communication between two DASH7-compatible devices occurs when they are brought within approximately 300 feet of one another and a wireless "hand shake" is initiated by one or both devices. The underlying layers of DASH7 technology follow the globally implemented ISO 18000-7 standard.

This technology has a wide range of applications from tags for supply chain to mobile phones that allow users to monitor energy usage in their homes.

What about ZigBee?

To give you a better understanding of where this technology fits in when compared to ZigBee (the current standard for Sensor Networks) we have done a direct comparison of the two technologies.

DASH7 vs ZigBee

ZigBee vs DASH 7

Who are the early adopters?

   •   Analog Devices
   •   ST Microelectronics
   •   Texas Instruments
   •   Dow Chemical
   •   Eyigia Systems
   •   Hi-G-Tek
   •   KPC
   •   Lockhead Martin
   •   Michelin
   •   Orthrop Grumman
   •   RFind Systems
   •   Savi

Applications

    •    Supply Chain Management
    •    Inventory/Yard Management
    •    Manufacturing and Warehouse optimization
    •    Self-Replicating Light data networks

This technology looks promising, however it is yet to be seen how widely DASH7 will be used in the Industry and if it will be able to replace/co-exist with other competing technologies.
