WizziKit is a DASH7, LoRa and Sigfox Wireless Sensor & Actuator Network Kit

Over the last few years, I’ve written several article about LoRaWAN, Cellular IoT, and Sigfox based long range low power IoT solutions. DASH7 is another LPWAN (Low Power Wide Area Network) standard that operates on the same 868 and 915 MHz ISM bands as LoRa and Sigfox, but has much lower power consumption, and the cost of a shorter range up to 500 meters, instead of the 5+km associated with LoRa or SigFox. The DASH7 Alliance Protocol (D7A) is an Open Standard, and if you want more details you can download version 1.1 of the specifications on DASH7 Alliance website. I’m writing about DASH7 today thanks to an article on ST blog about Wizzilab’s Wizzikit, an evaluation kit and framework for DASH7 with a gateway, and several nodes that can also optionally support LoRaWAN and Sigfox protocols. The kit is comprised of the following items: WizziGate GW2120 Ethernet/Wifi/Dash7 gateway – based […]

RadioShuttle Network Protocol is an Efficient, Fast & Secure Alternative to LoRaWAN Protocol

LoRaWAN protocol is one of the most popular LPWAN standards used for the Internet of Things today, but some people found it “lacked efficiency, did not support direct node-to-node communication, and was too costly and far too complicated for many applications”, so they developed their own LoRa wireless protocol software called RadioShuttle, which they claim is “capable of efficiently sending messages in a fast and secure way between simple LoRa modules”. Some of the key features of the protocol include: Support for secure or insecure (less time/energy) message transmission, multiple messages transmission in parallel Unique 32-bit device ID (device number) per LoRa member, unique 16-bit app ID (program number for the communication) Security – Login with SHA-256 encrypt password; AES-128 message encryption Air Traffic Control – Nodes only send if no LoRa signal is active on that channel. Optimized protocol –  Message delivery within 110 ms (SF7, 125 kHz, free […]
