1. Open Standard of Ultra Low Power Mid-Range Sensor and Actuator Communication
- DASH7 Alliance Protocol specification is free downloadable
- Open Source Stacks available
- Communication range from a few meters to a few kilometer
- Multi-year battery performance
2. Blast your sensor network with DASH7
Data transfer is abrupt and does not include content
such as video, audio, or other isochronous forms of data
For most applications, packet sizes are limited to 256 bytes.
Transmission of multiple, consecutive packets may occur
but is generally avoided if possible.
- DASH7’s main method of communication is by command-response,
which by design requires no periodic network “hand-shaking” or
synchronization between devices.
DASH7 does not use discovery beacons, end nodes can chose to
respond only to pre-approved devices.
A DASH7 system of devices is inherently mobile or
transitional. Unlike other wireless technologies DASH7 is
upload-centric, not download-centric, thus devices do not
need to be managed extensively by fixed infrastructure
(i.e. base stations) to respond only to pre-approved devices.
3. Ultra Low Power
- Low energy per bit transmitted / received (increased battery life)
- Narrow band low silicon complexity (low power consumption)
- Low infrastructure deployment cost (no need of repeaters, relays, system “tuning” or “calibration”)
4. Seamless Indoor and Outdoor use:
- Even in presence of concrete, metal and water
- Acceptable frequency band in most regions
- As an example of sub 1 GHz spectrum the frequency of 433 MHz is not true ISM band worldwide, but close to it
- No interferences generated by Sub-Gig Bands systems with any of licensed devices such as Wi-Fi, etc.
- Avoids the use of busy 2.4GHz channels
Beyond Wireless Communication
5. Optimal RF performances:
- Low signal attenuation – very good range – No Line of Sight Transmission
- Sub-Gig Bands have significantly lower signal attenuation than higher ISM frequencies (23dB and 15dB less attenuation that 2,450 MHz)
6. Context Aware Sensor and Actuator Data Propagation System
- Event based data propagation based on sensor value changes
- Configurable through file system
- Handles scheduled scan cycles
- Handles queries from other devices
- Handles queries and notifications on file changes
- File system configurable over the air
