SMART METERING

Added value for businesses and customers through NB-IoT

Cost reduction: no manual meter reading required anymore

Exact daily measurements

No cost for hardware and maintenance of own local networks

Why Inventing a New IoT Technology?

NB-IoT in a Nutshell The “DNA” of NB-IoT

6

Proven LTE-based security mechanisms

High security

Direct connectivity of the sensor. (No installation and maintenance of local networks/gateways required)

Plug & Play

+20 dB link budget (compared to GSM)

Deep indoor penetration

Worldwide 3GPP industry standard on operator-managed networks in licensed spectrum

Worldwide standard

1) Assuming equivalent of 2 AA batteries and typical traffic pattern 2) Dependent on network utilization and signal strength

Bidirectional, infrequent transmission of low data volumes. Data rates 600 b/s – 250 kbit/s 2)

Low data volume

Up to 100x more devices per cell (compared to GSM)

Billions of devices

Radio module <$5 (industry target), lower total cost of ownership

Low cost

Up to 10 years of battery-powered operation 1)

Low energy consumption

Offering both standardized network and service layers: Added value for an operator

oneM2M standard will be widely adopted in IoT devices and IoT platforms

R&D project to connect IoT devices and IoT platforms of different vendors to the Cloud of Things ensuring interoperability.

oneM2M capable adapter, applicable also to, e.g., Smart Home or Industry 4.0.

Conclusion

12 25/10/2017

NB-IoT meets the LPWA (Low Power Wide Area) market requirements, e.g. low-power consumption guaranteeing 10-year battery life,

low cost terminal, plug and play, high reliability and high carrier-class network security.

Short time-to-market of new services is possible.

Added value for operators: offering both standardized network layer and standardized service layer.
