DASH7 excels at connecting things that move, unlike most wireless data protocols which are limited to fixed or static applications. DASH7’s built-in query capability allows for “instant-on” connections with passing cars, buses, or people jogging, unlike WiFi or Bluetooth. DASH7 re-invents wireless P2P communications in ways other technologies can’t come close to matching.
Unlike WiFi or Bluetooth, DASH7 operates in wireless radio spectrum which provides for both long range (up to many miles in most markets) and excellent indoor signal propagation. HVAC ducts, chicken wire, and concrete walls are the kinds of obstacles that DASH7 penetrates or “bends” around that competing technologies cannot. Learn more …
DASH7 requires a tiny trickle of power to communicate between devices. A simple coin cell is enough to power most DASH7 devices for many years, but DASH7 even supports energy harvesting (like solar cells) unlike most other wireless protocols. Learn more …
DASH7 was designed to support precise indoor location from the outset, in combination with RSSI-based location engines. Precise to within 1 meter indoors, DASH7 offers an unparalleled combination of location accuracy, low power, and low cost for mobile advertising, mobile commerce, and other indoor or yard-based location applications.
DASH7 was designed with security in mind from the beginning. DASH7 enables “cloaking” of devices and enables them to remain “invisible” until an approved device initiates a communication. Second, DASH7 supports AES 128 cryptography, including public key encryption, as well as many other private- and public-key cryptography standards.
DASH7 components are inexpensive. Single chip silicon can be purchased in volume for $2 each, while coin cell batteries, antenna, and housing can be purchased in volume for less than $1. Your unique requirements will determine the ultimate cost structure of your products, but DASH7 is highly competitive with other wireless protocols. In addition, DASH7 is an open standard, which means your company will not be “locked” into a single company’s proprietary (i.e. expensive) solution but rather will have multiple supply options for components, products, software, and services.
As an open standard using a single global frequency, DASH7 stands apart from the competition. Unlike standards that specify only two layers of the OSI stack, DASH7 defines up to seven layers, which means getting your DASH7 device to interoperate with another company’s DASH7 device is just massively easier. Haystack also founded the DASH7 Alliance whose primary mission is to test for conformance and interoperability across DASH7 vendors. Working with Haystack makes your company’s job of interoperability even easier.
