RTLS.

1. RTLS – Do’s & Don’ts

   1. Do install BluFis in a high location. LOS is always a good thing.

   2. Do a Wi-Fi Survey. Check the Up-stream speed. (100kb/s up per BluFirecommended).

   3. Do Wi-Fi Signal check in all areas where BluFis will be installed.

   4. Do- If a Cellular Hotspot to be used, check Cellular signal with carrier. Check Up-stream speed.

   5. Do place more BluFis in areas where higher accuracy is needed.

2. RTLS – Do’s & Don’ts

   1. Don’t install BluFis in low areas near the floor.

   2. Don’t install BluFis behind metal items. Ensure there is no metal directly in-front of the BluFi – Tables, chairs, cabinets, etc, that are within

6

3. 1. six feet or less from the BluFi is not recommended.

   2. Don’t walk away without checking ground-truth. 

4. RTLS Best Practices

   • Install BluFI in each corner of the Building

   • For RTLS, deploy a grid of BluFI every 8 meter.

   • Physically mark BluFi with a #. Physically mark the location of the BluFi with that respective #. This is to ensure that the same BluFi is plugged back into its original location; avoiding any unintentional swaps

   • All bluFI should be on the same plane (ideally at 2 m level, but most commonly at ceiling level)

   • Metal should not be blocking the line of sight to each bluFI and No bluFI should be close to the floor (concrete)

   • For good

Trilateration

5. • trilateration, the beacon should be 'seen by

at

6. • ' a minimum of

6

7. • six BluFis. Meaning there

's that many BluFi

8. • are six BluFis within a 20~25

Meter Radius from Some improvement of oscillation may be improved

9. • meter radius of where you are tracking.

10. IMPORTANT: Make sure BluiFis are on Multi-Channel mode, and every beacon is using Asset Tracking template.
11. Do note: some oscillation of beacon position is normal for non-calibration RTLS. For more accurate and faster latency, calibration is preferred. To improve oscillation in non-calibration RTLS, see point f below.

12. • For better accuracy ,signal level threshold ideally should be around -70dBm.

    • Bluzone lat/long need to match the physical location of BluFi, always! If there is a need to change physical location of the BluFi, you need to change its location on Bluzone map, as well

    • There should be at least 128 kbs upload bandwidth available on the network for each BluFi installed -128 x # of BluFi. This is to avoid any latency in tx of data from BluFi to the cloud

    • BluFi connection to the internet needs to be confirmed. A successfully configured unit is always connected to the internet. Details on compatible WiFi are available here.

    • It is not required to have all BluFis connected to the same WiFi network, as long as all are connected to the internet

    • Each beacon should be seen by 6 to 8 BluFI at any point to achieve a good RTLS experience

    • Beacon position oscillation can be reduced by selecting the settings tab and changing the 'Bucket', 'Overlap' & 'Period' each to 3000 ms or more. This will add latency of

approximate

13. • approximately 5 seconds or more to the results, but it will smooth the oscillation of the location. Increasing it to 4000 or 5000 ms will

smooth

14. • stabilize the oscillation even further.
