Implementation Challanges
Wireless Communication
Security
Battery life
Time to market
Let’s look at two examples…
Bike Integration Module
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
Bike Integration Module
COMMUNICATION
Several wireless technologies integrated into
a small module (GSM, GPS, BLE, ANT, NFC)
Antenna design challenge due to small size
Isolation between different antennas
Bluetooth/ANT concurrent operation
challenging
Bike Integration Module
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
Bike Integration Module
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
Bike Integration Module
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
Optical meter reader
Product description
Automatic readout of analogue rotary
counter meters
Camera picture processed with OCR
Gives digital life to analog meters
Easy installation by anyone
Optical meter reader
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
Optical meter reader
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
Optical meter reader
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
Future of IoT
Low Energy Wireless Networks
LoRa – Long Range radio
ISM Band
LoRa WAN – Low Power Wide Area Network
Sigfox
ISM Band
Properitary low engery wireless network
Narrow-Band IoT
Licensed spectrum (Quality of Service)
Large area coverage, low cost, long battery life
