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
