10. Connectivity

11. ADVANTAGES
Highest throughput
DISADVANTAGES
Spectrum utilization,
power requirementsWifi
Bluetooth beacons Low application throughput
Bluetooth
LPWA
Cellular
No power requirement
Low 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
Near range

12. LPWA
Connectivity designed specifically for IoT

13. 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

14. Unlicensed Spectrum
EC-
-m
Licensed Spectrum
LPWA: Technologies

15. Cellular-IoT
Licensed Spectrum for IoT

16. 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

17. Cellular IoT (CIoT)
connectivity we WILL have

19. NB-IoT
a bit intro

20. 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

Obviously, I’m not a telco guy
Won’t Go details ON NB-IoT infra

33. What about the Programming?

34. 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

35. (Video) The moment of truth:
1st ever connecting to NB-IoT network, using AT command
Watch it on YouTube: https://youtu.be/LhK7WU6FpPI

36. NB-IoT
in Indonesia

37. Disclaimer
I’m bound to an NDA :P
MANY THINGS I CAN tell you in person

38. 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

39. 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 frequency
range (mhz)
1 1920 – 1980 2110 – 2170
2 1850 – 1910 1930 – 1990

18 815 – 830 860 – 875
19 830 – 845 875 – 890
20 832 – 862 791 – 821
26 814 – 849 859 – 894
28 703 – 748 758 – 803
66 1710 – 1780 2110 – 2200
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

40. Choose SARA-N200*
*Not final. Official band is not agreed yet

41. 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.

need one of this
*You can’t buy it easily, though.
Need to be recommended by a specific vendor

49. NB-IoT is NOT a
hype!
It’s real, and Indonesia is taking part
