Are you Bluetooth or WiFi? Why not be both!

When this blog was much younger, I shared a post asking if you were Bluetooth or WiFi.  The premise was simple: Bluetooth represented slower and small-scale, with the added benefit of low-energy. You could make numerous connections nearby and interact with them all seamlessly.  Does that sound like you?  If not, perhaps you were WiFi.  Like your electronic namesake, it stood for high-speed, long reach, and high energy.  Decisions happened quickly, decisively, and everything was high-energy.  However, everything came back to a central location, rather than the point-to-point nature of Bluetooth (Mesh WiFi wasn’t yet a thing).

One wasn’t better than the other, simply a different approach.  Which is necessary in our varied industry.  What works in one place may not provide the same results elsewhere.

And then I got myself an Apple Watch.

What does that have to do with the topic?  As I learned about its capabilities, I discovered an interesting feature.  The normal operation is for the watch to remain connected to my iPhone through Bluetooth (the Low Energy standard, actually, taking our previous metaphor to the next level).  However, if the phone is not available or otherwise out of range, the watch will attempt to connect to known WiFi networks.  It’s the fallback, since, as you learned, WiFi uses more power, thus decreasing the battery life.  Yet the watch adapts as it must.
