For people needing wireless -- if info qty is small and reliability is important just use the 433Mhz and 868-915 MHz packages -- like TI sells -- see CC110L in TI store for example. It's worth evaluating. and relatively cheap to try.
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. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
