  "content": "<p>Hello everyone,</p>\n<pre><code> After staring the data for while, I decided to go after WIFI data for start and I noticed in certain WIFI IDs repeats itself in same waypoint with different RSSI levels, since I have no idea how WIFI indoor position works I did little reading. Based on my reading I hope I got it right, lower the RSSI level further the phone from wifi. if so RSSI levels changes a lot maybe because of noise or device that recorded the data moved a lot I don't know (maybe need more reading) most of the readings go from -50 to -80 based on my manual labor with data. But interesting fact was RSSI count weren't the same for each WAY POINTS and for each floor. My highest count was 50 for certain WIFI id on certain WAY POINT on F1 floor RSSI levels were -52 to -87 then same floor different WAY POINT another count were 37 with RSSI levels were -57 to -82 and F4 with 2 different WAY POINTS one had 2 RSSI count that  were -66, -77 and second didn't even have any RSSI reading. \n\n  So based on I started to think COUNT of RSSI reading might be a good indicator of phone location. Please let me know what do you think about this. \n</code></pre>\n<p>Thanks </p>",
