FAQ


CAN DASH7 TECHNOLOGY BE USED ANYWHERE IN THE WORLD OR JUST IN THE U.S.?

Sub 1 GHz is an approved frequency range accepted in all parts of the World, There are some local differences that do not impact the use model. DASH 7 Alliance has thoroughly researched the spectrum issues and continues to work with the International and local regulatory bodies.  Sub-GHz frequencies can be used.  For example 433MHz is widely used but power levels and duty cycles must be adjusted for different parts of the world.  868MHz can be used in Europe while 915MHz is used in the USA.

HOW BIG IS THE DASH7 MARKET OPPORTUNITY?

All Radio Device markets are expanding rapidly as the needs and requirements of the user are met by innovation and regulatory relaxation, lowering component costs and speeding time to market. The Alliance product, and it’s related standards, are no different in this respect and offer robust, qualified markets based on Alliance research that offer high volume and ongoing sustainability.

HOW DO DASH7 AND THE ISO 18000-7 STANDARD RELATE?

DASH7 members are often members of the standards community in their particular community and completely support all standards where the use of 433 and related Sub 1 GHz technologies are deployed. The Alliance actively supports all the ISO, CEN, ANSI, and many other standards  process by addressing and resolving technical issues more quickly than can be accomplished through the standards body own  process.

HOW DO I JOIN THE DASH7 ALLIANCE?

Contact info@dash7-alliance.org.

HOW DO MY PRODUCTS BECOME DASH7 CERTIFIED?

Currently their is no certification program.  However plug-fests do occur during alliance meetings to help ensure inoperability.

HOW DOES DASH7 ACCOMPLISH ENCRYPTION?

Encryption over-the-air or within the tag is currently a DASH7 program to consider encryption. Due to the power of modern silicon, both private key (i.e. AES 128) and public key (i.e. ECC, RSA) techniques are viable options.

HOW DOES DASH7 BEAT TECHNOLOGIES LIKE WIFI AND ZIGBEE?

WiFi and ZigBee technologies are designed to maintain high data rate, download-centric networks of relatively static devices. They are not designed to elegantly address the BLAST (Bursty, Light-data, Asynchronous, Stealth, Transient) model, which is more suitable for upload-centric networks like sensor nets, supply chain, asset tracking and others.

HOW DOES DASH7 TECHNOLOGY WORK?

DASH7 solutions may contain a pool of companion technologies that each operate in their own ways, but the commonality between these is that they use a Sub 1 GHz silicon radio as their primary means of communicating with other DASH7 products. Sub 1 GHz was chosen for its worldwide availability and the inherently resilient qualities of the signal at this frequency.

HOW IS DASH7 BETTER THAN ACTIVE RFID TECHNOLOGIES CURRENTLY ON THE MARKET?

DASH7 stack is small, allows for a full end-to-end file system, and allows any node to talk to any node at any time while maintaining low power.

IS DASH7 AN OPEN STANDARD?

DASH7 is a non-proprietary technology based on an open standard that anyone can use. Manufacturers and markets have the ability to deliver within the open context whilst maintaining attributes or protocol elements more appropriate to, for instance, the security of a user community or the appropriateness of the operating environment.

WHAT ABOUT RTLS?

RTLS systems can be implemented that leverage the advantages of Sub 1GHz frequencies.

WHAT APPLICATIONS ARE BEST SUITED TO DASH7 TECHNOLOGY?

DASH7 is an aggressively low power RF technology-set best suited to uses that have bursty, asynchronous communication between devices. In other words, you go in, you get the data you need, and you get out. Examples of DASH7 applications include supply chain management, inventory/yard management, manufacturing and warehouse optimization, hazardous material monitoring, smart meter and commercial green building development..

WHAT ARE THE ADVANTAGES OF DASH7 TECHNOLOGY?

The advantages of the Alliance Protocol is to provide simple, elegant and reliable interfaces for handling bursty, light-data, asynchronous, transient usage models. We call this “BLAST” and it transforms the use of 433 and related sub 1 GHz spectrum to  be tightly tuned for dealing with inherently mobile devices that need to upload small bits of information reliably.

WHAT ARE THE DASH7 ALLIANCE’S GOALS AND OBJECTIVES?

1) Facilitate solution development between end users, system developers and technology suppliers; 2) Develop excellent facilities for certification, interoperability and feature cross-comparison; 3) Integrate Alliance technologies into the relevant standards; 4) Identify, implement and certify companion technologies to all identified standards; 5) Through improved standards and cooperation, increase the global market size for ultra-low-power RF systems in the Sub 1 GHz market.

WHAT IS DASH7?

DASH7 is the organization of choice for those concerned with the use of, development of and implementation of product in the 433 MHz and sub 1 GHz spectrum active market and approved applications allowing for the addition of the Alliance Protocol, where appropriate, to a suite of products in a particular sector in a uniform and interoperable mode.

WHAT IS THE KEY ATTRIBUTE THAT MAKES DASH7 TECHNOLOGY SO EFFECTIVE?

The widespread use of active, low cost, low power radio tool sets that are transforming the market for users and vendors by offering low cost, high performance systems with interoperability.  Time synchronization of messages allows end-nodes to talk directly to end-nodes without any line- powered router all while retaining low power for battery operation with multi-year life spans.
