What is DASH7?

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

Who has the 2nd Largest Communications Network in the World ?

India has the 2nd largest communication network in the world, having a tele-density of 28.33% and is one of the fastest growing wireless markets, with a total subscriber base of 325.78 million at the end of June 2008, adding 9 -10 million subscribers a month.

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.
