DASH7 Alliance Protocol (D7A) is an open-source wireless sensor and actuator network protocol, which operates in the 433 MHz, 868 MHz and 915 MHz unlicensed ISM /SRD band.

The de Havilland Canada DHC-7, popularly known as the Dash 7, is a turboprop -powered regional airliner with short take-off and landing (STOL) performance. Variants were built with 50–54 seats.

The DASH7 Alliance Protocol (D7A) is an Open Standard for bi-directional, sub-Ghz medium range wireless communication tailored for ultra lower sensor-actuator applications using private networks. D7A stems from ISO 18000-7 for Active RFID and operates in the sub-GHz ISM bands.

In this paper we introduce important aspects of the recently published DASH7 Alliance Protocol v1.0 specification for wireless sensor and actuator networks. The main contribution of this paper is the discussion of the different communication schemes and the accompanying trade-offs which can be used when designing a DASH7 network.

2018年10月23日 · In this paper, we address the mobility of the things and the connectivity in each of the three LPWAN standards: LoRaWAN, DASH7, and NB-IoT. In particular, we show how the mobility of things can be achieved when transmitting and receiving data. Then, we provide a general and technical comparison for the three standards.
