Ask a Developer: Understanding MQTT Topic Structures

MQTT is one of the most popular IoT communications protocols for wireless sensor networks. Its publish-subscribe architecture can streamline, simplify, and scale the creation and provisioning of potentially massive edge networks—if you structure the pubsub technology appropriately from the start. In his time at AWS IoT, consultant and DevHeads cloud and networking expert Lukasz Malinowski gained a mountain of experience working with large-scale IoT deployments. He also and learned how to build MQTT networks for extensibility from the ground up. On this DevHeads Demo, Lukasz outlines key concepts for understanding and properly structuring MQTT topics in a Roblox environment to explain what it takes to ensure the success of your IoT deployment long term.

MIMO technology!

Hello team, Can anyone of you please explain to me about MIMO technology!...

Solution:

This is quite an amazing technology. I first heard about this from my uncle who works at Continental automotive and then saw one team at BOSCH running some tests with demo car and crashes. This is automotive use case. Generally, MIMO is a type of RF technology expanded as Multiple Input, Multiple Output which only means that instead of one Tx and Rx, there is an array of it. I have seen one time a 64x64 array of patch antennas....

Implement edge computing in a battery-powered IoT device with limited resources

Morning everyone ! Is it feasible to implement edge computing in a battery-powered IoT device with limited resources? What are the trade-offs and potential challenges in offloading computation to the edge?

Solution:

Edge computing provides the following benefits: * Real-time local data processing enables immediate actions even without connectivity with the backend system. * Pre-processing and analyzing data before sending it to the backend system to reduce the payload size and communication frequency (resulting in lower cost and potential battery saving). * In case of connectivity issues, the device can locally store messages and transmit them once it is back online (you won't lose telemetry data during a network outage). ...
