SMS is probably the most efficient method of transmitting information in M2M. SMS uses the more powerful control channel in the cellular connection. Most M2M information is small, bursty status updates or tiny control signals, such as "Arm" or "Disarm". Leveraging Twitter to deliver SMS messages to other machines that "Follow" each other is a simple way to enable autonomous M2M among machines.
yeah, we're talking about tiny, minute wireless chips, terry. Most don't even need 3G capability, it's possible in most cases to get away with 2G. Standardizing things could be a little difficult though as there is still the whole CDMA vs GSM technology split....
machines talking to each other is a very interesting idea. How about the standardization of the "talk" protocol? What kind of wireless technology is needed? I guess the technology must be very power efficient otherwise the electric bill will be a problem.
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.
