I wanted to see if anyone could provide some information on a problem with tight constraints. Given a limited power source, what kind of limitations do we face in radio communication with an object at ~40km altitude? That said, neglecting variables like geographical location, weather, interference. I'm working on a very limited power supply so providing enough energy to compensate isn't necessarily an option - or my first consideration. Lets say hypothetically that a ground station is within the payloads VHF/UHF line of sight. Are their very low power alternatives i should look into or is my only realistic option considering limited communication (again, narrowing power req.). Again, any and all input is welcome; If there's any place I'd want to hear a strangers two cents on a current objective it's here. Thank you so much.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
