DASH7 is a new wireless sensor networking technology using the ISO/IEC 18000-7 standard for active RFID, operating at in the 433 MHz unlicensed spectrum.

DASH7 provides multi-year battery life, range of up to 2 km (potentially farther), low latency for tracking moving objects, small protocol stack, sensor and security support, and data transfer of up to 200 kbit/s. DASH7 is the name of the technology promoted by the non-profit consortium called the DASH7 Alliance.

What is The DASH7 Alliance?

The DASH7 Alliance was formed to advance the use of DASH7 wireless data technology by developing extensions to the ISO 18000-7 standard, ensuring interoperability among devices, and educating the market about DASH7 technology. Formed in 2009, the Alliance now has more than 20 members. Manufacturers, systems integrators, developers, regulators, academia, and end-users all work together to promote the use of DASH7 technology in a wide array of industries and applications.

The goals of the DASH7 Alliance are to:

• Develop improvements and extensions to the ISO 18000-7 standard
• Work to ensure that products claiming DASH7 capabilities comply with DASH7 specifications
• Encourage the development of products using DASH7 technology
• Educate consumers and enterprises globally about DASH7 technology

The DASH7 protocol combines a low power wireless sensor networking (like Zigbee) with RFID. It operates in the 433 MHz unlicensed spectrum, communicates at 100 kbps, penetrates concrete and water, and connects over long distances at low power.

The DASH7 protocol features:

• Multi-kilometer range and excellent penetration of walls, floors, and things made of water
• Extremely low power draw (measured in microwatts) and multi-year battery life
• A maximum bitrate of 200kbps
• Supports tag-to-tag or “multi-hop” communications, sensors, and public key encryption
• Multi-channel architecture for real-time locating capability
• Extremely low latency for tracking moving objects
• Operation in the license-free and globally available 433 MHz spectrum
• “Out of the box” interoperability using a single global frequency
• The brand given to the ISO 18000-7 standard for active RFID

Radio frequency identification (RFID) technology was introduced during the first decade of the new millennium with much fanfare. But the radio tags were practically limited to just replacing conventional barcodes.

In this climate, experts point out that the hype originally promised by RFID would be realized only when its applications go mobile and Korea is currently leading the world in the shift toward mobility. Mobile RFID is based on portable readers imbedded in such wireless devices as cell phones with which people can check detailed data of groceries or movie previews by attaching their handsets to radio tags on vegetable wraps or movie posters.

“No matter how many radio tags are around us sporting fancy applications, its usefulness would not be realized if a number of people do not carry the readers,” a spokesperson at the Mobile RFID Forum said.

“In my view, the idea of ubiquitous RFID readers will be materialized when they are incorporated in such devices as cellular phones or other handheld devices. Korea is setting the global trend.”

Entities both from the public and private sectors convened in 2004 to form a Mobile RFID Forum involving the state-run Electronics and Telecommunications Research Institute (ETRI), Samsung Electronics, LG Electronics and SK Telecom. The companies and organizations have finished pilot tests geared toward checking the commercial viability of mobile RFID, faster than competitors in other countries. On top of commercial deployment, Asia’s fourth-largest economy has taken the initiative in technological advances as demonstrated at an international conference on RFID standards. Korea hosted the conference, which started Monday to continue through March 26 on Jeju Island, and asked for 16 technologies to be made global standards, or around 16 percent of the 68 overall proposals. Of these, observers predict that the country’s offers in mobile RFID and real-time location systems are highly likely to be endorsed because the country is ahead of the pack in these segments.

Then, Korea will be able to preempt the mobile RFID markets, which are expected to explode in the not-so-distant future, said the Ministry of Knowledge Economy. The RFID tag is a small integrated-circuit chip together with a radio circuit. The tiny tags emit radio waves so that its identification code can be scanned from a distance through a reader. The cutting-edge technology has been expected to offer a variety of information on any product like their ingredients, origins, producers and transportation histories as well. However, the hitch was that the fixed reader of the mobile RFID was not available to the general public. This prompted many countries to come up with wireless readers but they were prone to mistakes in recognizing the tags accurately. To tackle the problems, many Korean researchers have worked on improving the precision of the readers in motion to make a substantial advancement in the studies, according to the Mobile RFID Forum.

India is likely to leap-frog from being the twelfth largest consumer market in the world to become the fifth largest, reported by a recent McKinsey study. Aggregate Indian consumer spending is estimated to more than quadruple to US$ 1.77 trillion by 2025. The WiMAX ecosystem in India is expected to increase from 500 million in 2010 to 650 million in 2011 for Macro & Microbase Transceiver Stations (Tss). The enterprise mobility market is anticipated to grow at a CAGR of 14.5% by 2012-13, with expected revenues of $250 million from India by 2009. The Indian economy has been growing at an average rate of 8.8 percent per annum, with 2006-07 growth rate of 9.6 percent being the highest in the last 18 years. The total market for semiconductors in India (including imports), grew to $2.82 billion in 2005 and is expected to reach $12.67 billion in 2010 and further grow to $36.30 billion in 2015, growing at a CAGR of 29.8 percent, according to ISA-Frost & Sullivan.
