Bonus webinar: Why do we all need to use CheckFox and what’s so Sigfox special about it?

  1. 1. CheckFox All the documentation is available at ask.simplehw.eu
  2. 2. About this webinar Who is this webinar insight for? Sales, technical pre-sales, sales, support SO’s and integrators, IoT platforms. Technical level: intermediate Format: 30 mins presentation + 15 mins Questions & Answers session Speaker: Pavel Sodomka, CEO at Simple Hardware
  3. 3. Usage scenarios 1. Sigfox operators need to compare real coverage with a predicted model 2. Sigfox integrators need to measure coverage before starting PoC 3. Field workers need to measure coverage before starting field device installation
  4. 4. Measurement methodology https://docs.google.com/document/d/1i1WBlnIm_n1ApQsaVRaKTEInQ1GHgW-hPbe XDIOjDPw/edit#heading=h.lbpe1yvyl5fz A. Does the predicted coverage match the actual coverage? B. Will a reference device work at the installation spot? C. What is the attenuation between reference measurement and final destination? D. What is the reliability of the reception over time? E. Does my HW device work as well as the reference device?
  5. 5. Measurement protocol Aim of the measurement: ❏ A Coverage ❏ B Final place coverage ❏ C Attenuation ❏ D Reliability in time ❏ E Final HW performance Name of the person and his qualification: ID of the reference device used: Date: Time: Place: Photos stored at: Any remarks: (extreme weather etc.):
  6. 6. Before measurement ❏ Ensure that you are using a reference device ❏ Check the antenna not being loose and using a proper antenna ❏ Check the device voltage ❏ Take a photo of the device ❏ Decide what you want to measure and how you will evaluate the results
  7. 7. Reference measurement ❏ Place the device 1.3 m above ground under open sky at least 1m away from any obstacle ❏ Hold it with vertical antenna and don't move. Ideally place the device on a tripod or holding it in your hand should be fine ❏ Take a photo of the device ❏ Take a photo of the environment ❏ Ensure you have a GPS fix ❏ Select Outdoor at 1.3 meter (4.3feet) Reference - REF in Main menu ❏ Select how many Messages you want to send ❏ Ideally repeat the measurement three times shifting the device in a triangle by 8-9cm (lambda/4), ❏ Check that in the Dashboard, the predicted coverage matches roughly the measured coverage In case the predicted coverage is much worse, please contact the local Sigfox operator immediately and provide them with photos and GPS position ❏ Assess the results of the A aim
  8. 8. Final installation place measurement ❏ Do Reference measurement ❏ Do between-the-steps measurements (Indoor for indoor installations, Outdoor Ground Level for Underground installations (parking sensors). Always take a photo ❏ Select your final location ❏ Take a photo of the device and the environment ❏ Select location in Menu and select FInal destination measurement or Final with delay in case the final destination is behind closed doors or the device needs to be lowered on a string, the measurement will start in 30 seconds ❏ Assess the results of the B Final place coverage aim ❏ In the Checkfox dashboard, compare the results to the Reference measurement and asses the C Attenuation, then subtract the SNR
  9. 9. Reliability over time period ❏ Make a time series measurement at the Final destination with intervals of either 10 minutes or 1 hour ❏ Assess the D Reliability in time by accessing the message lost
  10. 10. Comparison with final HW ❏ Do the Final installation place measurement with the reference device ❏ Take a photo of your Final HW in Final destination ❏ Do the Final installation measurement with the final device ❏ Assess the E Final HW performance. Look especially at message loss and how many repetitions of the device you see. If you see only 1 repetition in most cases the battery design is bad, and battery doesn't have enough power to emit the second and third repetition. Or the device antenna could be detuned and does not perform properly.
  11. 11. Resume A. Does the actual coverage match the predicted one? Same-better-worse? B. Does the reference device work in the Final installation? Yes-no-little bit? C. What is the attenuation of the Final installation in comparison with the Reference measurement? Rate as a number between 0 and 70. D. How is the long-term reliability of messages? Excellent-good-bad? E. How does my HW perform in comparison with reference one? Better-same-worse-far worse?
  12. 12. What is inside the CheckFox? GPS module for precise position GSM module for data transmission Memory for data logging WiFi module for collecting MAC addresses, which is usable either for position fixing of the device or comparison between Sigfox Atlas, Sigfox Atlas WiFi, Google geolocation public network services and others Over the air upgradable firmware
  13. 13. CheckFox 2.0 ● Sturdier construction ● Better antenna fixing ● Water resilient USB-C connector ● WiFi module ● Global prepaid SIM card with €10, switchable for your own
  14. 14. Logic behind measurements ❖ Tell the device where you’re measuring (just a tag) ➢ Reference measurement at 1.3 m outdoor (this should match coverage prediction) ➢ Outdoor above the height ➢ Ground level ➢ Indoor ➢ Deep indoor ❖ Tell the device what you’re measuring (just a tag) ➢ Survey ➢ Final destination ❖ Tell the device how many times to measure ❖ Tell the device whether you want to do periodic measurement Guide the user to collect metadata before the measurement
  15. 15. Periodic measurements Ideal for 2 scenarios ● Measure with the GPSwhile driving/travelling (1 min, 10 min, 60 min intervals) ● Static location over a time period measurement without the GPS (10 min, 60 min intervals) Downlink test Debate about whether budgetlink and reliability is the same in both directions
  16. 16. Service menu Many things described in the documentation Most important: ● Datalog update in case GSM is not present at the location ● Firmware update ● About: ID, IMEI, RC etc. ● RC2/RC4 switch
  17. 17. Checkfox dashboard -https://checkfox.simplehw.eu/ 3 ways how to work with collected data: ● API (described in the documentation) ● Dashboard and csv and xls exports ● Dashboard and dashboard visualisations
  18. 18. Functions of the dashboard 1. Device setup 2. User management and rights setup 3. Data listing 4. Data export 5. Data visualisation 6. Data comparison
  19. 19. Now it is time for your questions!
