This is a nice teardown but there are several things that are not clear, how do each of the competitors deal with stability, drift, and an integrated inertial solution? Most applications would benefit from the very best drift correction, which was a big problem in the recent past.
Most engineers want a complete inertial solution coming out of a chip of this class and other than price that might be the most important aspect of selection. I wish there was a chart with the major specs and capabilities listed for comparison.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
