Byte Lab made a brief presentation of IoT Implementation Challenges and the future of IoT Connectivity, a theme that was presented to the audience in Vienna at “M2M/IoT CE Forum 2017” and in Sarajevo at “IoT Summit 2017”.

Implementation Challenges:

  • Wireless Communication
  • Security
  • Battery life
  • Time to market

Our two examples…

BIKE INTEGRATION MODULE

Mobile22

Product description:

  • Cyclist performance tracking
  • Central hub to which fitness sensors connect: HR, oximeter, power, cadence…
  • Together with GPS tracking, sensor data is sent to the cloud
  • Training performance metrics and data visualization

 

Communication:

Several wireless technologies integrated into a small module (GSM, GPS, BLE, ANT, NFC)

  • Antenna design challenge due to the small size
  • Isolation between different antennas
  • Bluetooth/ANT concurrent operation challenging

Security:

  • Each device has to be authenticated
  • Secure link between cloud and device
  • Only encrypted messages are exchanged
  • Sensitive information stored in a secured way
  • Successful attack at one device does not expose other devices

Battery Life:

GPS tracking consumes most of the energy

  • Trade-off between tracking precision and battery life
  • Concurrent GPS / GALILEO operation bears additional power penalty
  • Tracking information pushed to cloud in bursts

Time to Market:

  • Different wireless integrations slow down regulatory compliance testing
  • Certified off-the-shelf modules vs internal development (modules increase unit cost)
  • Verification makes up most of the engineering time

 

OPTIC METER READER

June module

Product description:

  • Automatic readout of analog rotary counter meters
  • Camera picture processed with OCR
  • Gives digital life to analog meters
  • Easy installation by anyone

Communication:

  • Communication needs to work through five concrete floors
  • High sensitivity LoRa technology selected
  •            Trade-off between sensitivity / bit-rate and power consumption
  •            Device position not known, need for antenna which works in all directions
  •            Duty-cycle restriction based on regulatory standards

Security:

  • Encrypted LoRa RF communication
  • Wi-Fi security
  • TLS secure session with the could
  • Unique ID and truly random passwords
  • Proof to ”Man-in-the-Middle” attacks

Battery Life:

  • RF transfer consumes significant amount of energy
  •           Dynamic TX power output based on RSSI
  •           Dynamic LoRa parameters based on RSSI
  • Critical to achieve minimum sleep consumption
  •            Turn off power to circuits not used

THE FUTURE OF IOT CONNECTIVITY – LOW ENERGY WIRELESS NETWORKS
