Probably no one has heard of this, but NABU Networks was a huge turkey mainly because it was 10 years ahead of its time. NABU Networks was an Internet precursor in the 80's that streamed games over TV cable. Those 2 years we had NABU were the best 2 years of my childhood...
Um, I think the transputer ended up in most of ST's set top box chip sets. It nearly was chosen by Nokia to be their mobile phone chip, would have got it if they hadn't told the truth about cache sizes (which arm didn't...).
ISDN was never deployed by the telcos that still had to book years' worth of depreciation on their CAS T1 switches. In Europe, on the other hand, which was still building-out higher capacities, the switch from CAS E1 to ISDN-E1 happened much earlier. Same could be said of the massive build-out of coax cable for TV when fiber optics already existed (though in that case the cost of terminal equipment was still high).
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.
