NarrowBand IOT

NB-IOT, a new narrowband radio technology to address the requirements of the

Internet of Things (IoT).

The new technology will provide improved indoor coverage, support of massive

number of low throughput devices, low delay sensitivity, ultra-low device cost,

low device power consumption and optimized network architecture.

The technology can be deployed “in-band”, utilizing resource blocks within a

normal LTE carrier, or in the unused resource blocks within a LTE carrier’s

guard-band, or “standalone” for deployments in dedicated spectrum.

NB-IOT advantages like wide area coverage, fast upgrade of existing network,

low-power consumption guaranteeing 10 year battery life, high coupling, low

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

security, unified business platform management.

NarrowBand IOT

NB-IOT perfectly matches LPWA market requirements, enabling operators to enter

this new field. Many mobile operators have set up dedicated IoT/M2M business

units in order to serve the growing number of market requirement.

There are several inherent characteristics of the NB-IOT technology that makes it

the best for LPWA deployment.

Performance point of view, NB-IOT guarantees 20+dB coverage, ~1000x

connections, ~10 years using only 200 KHz bandwidth

NB-IoT: the advantages of being part of 3GPP

1. Use of the LTE ecosystem, leading to fast development, economies of

scale, and global roaming

2. Can be deployed as a simple addition of new software to existing LTE

infrastructure

3. A management framework exists, enabling large-scale deployments

4. Framework includes state-of-the-art security

5. Future feature growth for MBB and NB-IoT use cases

NarrowBand IOT specification

NarrowBand IOT specification

Low device cost/complexity : <$5 per module

Extended coverage : 164 dB MCL, 20 dB better compared to GPRS

Long battery life : >10 years

Capacity : 40 devices/house ~55k devices per cell

Uplink report latency : <10 seconds

** low-end “Massive MTC” scenario

IoT system architecture

• Architecture is based on evolved Packet Core (EPC) used by LTE

• Cellular IoT User Equipment (CIoT UE) is the mobile terminal

• NB-IoT Authentication and core network signaling security as in normal LTE

• evolved UMTS Terrestrial Radio Access Network (E-UTRAN) handles the radio

communications between the UE and the EPC

IoT Road MAP and network architecture

NB-IoT NETWORK DEPLOYMENT

M2M access technology contained in 200 kHz with 3 deployments modes:

1. Stand-alone operation

2. Operation in LTE “guard band’

3. Operation within wider LTE carrier

(aka inband)

•Standalone deployment is mainly utilizes new bandwidth

• where as guard band deployment is done using the bandwidth reserved in the guard band of the

existing LTE network,

•In Band on the other hand makes use of the same resource block in the LTE carrier of the existing LTE

network

In summary, Standalone and Guard band deployment options tend to offer the best performance in terms

of improved indoor coverage, FDMA (GMSK) also offers about 20% power consumption saving and lower

cost.

NB-IoT Categories

NB-IoT NETWORK DEPLOYMENT classified under four use cases

categories.

Categories use cases

1 IOT Appliance Smart home application are deployed on short

range technologies like Z-Wave, Zigbee with home

gateway

2 Personal, Wearables , Smart bicycle , Kids monitoring , Pet

Tracking

3 Public Smart garbage bin ,Smart meter, Street light,

Alarms & Event Detectors

4 Industry. Asset tracking ,Logistics tracking ,Alarms & Event

Detectors

use cases can be different per operator, country and region or per addressed market.
