ADVANTAGES
Highest throughput
DISADVANTAGES
Spectrum utilization, power requirementsWifi
Bluetooth beacons Low application throughputBluetooth
LPWA
Cellular
No power requirementLow cost
Global coverage, application profile standards
Higher reliability for mission critical applications
CAT 1 and CAT 0 LTE for low cost, and ultimately NB-IoT high range data transfer
Power requirements, coverage “black spots”
Low data throughput
Less reliability for mission critical and real-time applications
Satellite
Breadth of coverage even in areas with limited infrastructure e.g. at sea or in developing countries
Price and interference due to weather conditions

Connectivity Option
LPWA Connectivity designed specifically for IoT
What is LPWA
Low Power, Wide Area Networks
Low data throughput = High sensitivity = Long range
(Relatively) low cost
Multiple Access = One-to-Many Architecture
Using licensed or unlicensed spectrum
Unlicensed Spectrum

Licensed Spectrum
LPWA: Technologies
Cellular-IoT Licensed Spectrum for IoT
Cellular IoT (CIoT) connectivity we NOW have
Fast, efficient Up to 10 Mbps for 4G LTE
Ubiquitous coverage
Reliable & secure
Not designed for IoT in mind
High power consumption
Relatively expensive: modules, data plan
Provisioning, manageability
Advantages Considerations
Cellular IoT (CIoT) connectivity we WILL have
EC-GSM-IoT LTE-M / eMTC NB-IoT
Low data throughput
Low power
Low device & deployment cost

NB-IoT a bit intro
What is NB-IoT
3GPP-standardised technology - Release 13
180 kHz RF frontend; Chipset cheaper than Cat M1, cheaper module
Can be deployed in: existing LTE bands, in guard bands, re-farmed spectrum, or standalone
Other details: Uplink: 250 kbit/s half-duplex (multi-tone), 20 kbit/s (single-tone)
Downlink: 250 kbit/s
Latency: 1.6s-10s
Device Transmit Power: 23 dBm
Coverage: 164 dB

What about the Programming?
NB-IoT: Software
Most NB-IoT modules:
Accessible via AT command
Support UDP/IP transport layer
Support Constrained Application Protocol (CoAP) application layer
No support for USSD, CSD, SMS, TCP/IP, HTTP, fax or voice
(Video) The moment of truth: 1st ever connecting to NB-IoT network, using AT command

NB-IoT in Indonesia
Disclaimer
I’m bound to an NDA :P MANY THINGS I CAN tell you in person
1 telco is doing heavy trial
1 big area is covered
~300ha, hidden in a plain sight
that I know…
NB-IoT: in Indonesia
1 use case is in heavy trial
For now, more coverage will be provided on use case basis
nb-iot frequency bands
22
Terminal Integration & Validation, Deutsche Telekom AG
The same frequency bands as in LTE
are used for NB-IoT, with a subset
defined in Release 13.
Most frequencies are in the lower
range of the existing LTE bands,
reflecting that for MTC, poor coverage
conditions is a concern.
band number uplink frequency range (mhz)
downlink frequencyrange (mhz)

NB-IoT: Frequency Bands
Currently, Indonesia uses Band 8* There’s suggestion to use Band 3, as all Indonesia telcos already support 1800MHz —> to be explored
*Not final. Official band is not agreed yet
Choose SARA-N200**Not final. Official band is not agreed yet
NB-IoT: SIM Card
Similar to other cellular connectivities, we need a SIM card to use NB-IoT
Any SIM card will do, but need to be “whitelisted” in telco-side
eSIM is still not supported yet in Indonesia. Not (really) technical reason.

NB-IoT is NOT a hype!It’s real, and Indonesia is taking part
Interested in adopting NB-IoT?
