Points to know when installing RTLS.
RTLS =E2=80=93 Do=E2=80=99s & Don=E2=80=99ts
Do install BluFis in a high location. LOS is always a good thi= ng.
Do a Wi-Fi Survey. Check the Up-stream speed. (100kb/s up per BluFi= recommended).
Do Wi-Fi Signal check in all areas where BluFis will be instal= led.
Do- If a Cellular Hotspot to be used, check Cellular signal with carrier= . Check Up-stream speed.
Do place more BluFis in areas where higher accuracy is needed.=
RTLS =E2=80=93 Do=E2=80=99s & Don=E2=80=99ts
Don=E2=80=99t install BluFis in low areas near the floor.
<= /li>Don=E2=80=99t install BluFis behind metal items. Ensure t= here is no metal directly in-front of the BluFi =E2=80=93 Tables, chairs, c= abinets, etc, that are within six feet or less from the BluFi is not recomm= ended.
Don=E2=80=99t walk away without checking ground-truth.
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 BluF= i 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, b= ut 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, the beacon should be 'seen by' a minimum of six = BluFis. Meaning there are six BluFis within a 20~25 meter radius of where y= ou are tracking.
For better accuracy ,signal level threshold ideally should be around -70= dBm.
Bluzone lat/long need to match the physical location of BluFi, always! I= f there is a need to change physical location of the BluFi, you need to cha= nge its location on Bluzone map, as well
There should be at least 128 kbs upload bandwidth available on the netwo= rk 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 c= onfigured unit is always connected to the internet. Details on compatible&n= bsp;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 ach= ieve 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 mor=
e. This will add latency of 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 stabilize the oscillation even further.
