This is one of the best RTLS presentations I watched. Pretty factual.

It's amazing. I have learned basic knowledge of Indoor Location easily. Really impressive.

Only by switching to 5GHz I guess you can get more reliable position since its dispersion of signal across some floor plan should be more predictable because it does not really penetrate walls and objects like 2.4GHz does. Of course it makes it harder when you consider that only by closing door or by standing in front of an antenna can alter signal so much but as a guy explained moving target gives a lot more info which can be filtered and converged into a usable location data. Also, since more and more APs are utilizing beam forming by only using a couple pf antennas I guess by creating an AP with a precisely manufactured phased array antenna you should be able to get much better client location accuracy. For those who dont know what beam forming and phased array antennas are, I highly recommend looking it up on youtube, its supper interesting.

Now in 2018 Google will be implementing IEEE 802.11mc for indoor positioning directly in Android as a framework any developer can tap into, so it won't be app-specific.

Reckon Point is getting meter accuracy using wifi and magnetic data, we can tell direction whether you're looking at the milk or coffee. We use the sensors in smartphones and compare the data of the building that we have mapped out with our proprietary robot. Would love to chat if anyone is interested,

very informative

If u control the client's and APs u can put them in low power mode for smaller spaces for a more accurate approximation? Am I right?
