Transcript of Communication Technologies for IoT

The Past
Communication technologies for
analysts predicting 20 billion devices by 2020
Internet of Things
by Anum Sheraz
Small IoT market dominated by
PAN (bluetooth, Xbee, etc)
WLAN (Wifi)
Low power & short range

fulfills users requirements
most of them with PAN/WLAN technologies
Why ?
Low cost
Low Power
Low Coverage
Why not Cellular Networks ?
Good coverage

with Dead zones!
High Power !
High Cost !
The Present
6.5 billion things are connected to the internet
Sounds allot ?
That's <
of all things that could be connected.
Why ?
too remote (
too inaccessible (
dead zones
or high in quantity (
cost and power
IoT application needs
The three C's



device and service cost
device life time
device coverage
Low Power Wide Area network
Protocol specifically designed for IoT applications
Long range
Low power
Low cost (relatively)
How ?
Wide spread network
higher coverage - Transmit small amount of data @ low rates
less processing power and less memory
Low current - can live long on batteries
Thus, low cost
LPWA Market leaders
v. low Bandwidth
low power
works on SigFox network
relatively more Bandwidth
more power
works on Semtec chip devices
The Future
4G (LTE)
High speed
internet for
Internet for Things
LPWA technologies comparison
Coverage parameters
I.e. A Machine:
2W, send data @ 10Mbps and covers 1000m
More coverage ?
2W, send data @ 8Mbps, coverage = 1300m
Less coverage ?
1.5W, send data @ 10Mbps, coverage = 700m
improve coverage:
1.5W, send data @ 8Mbps will now cover 800m
power = coverage
datarate = 1/coverage

power = 1/datarate
Standarised on June 2016 (successful trail on September 2016 by Vodafone & Huawei)
Claimed as best technology for LPWA network
Licenced Spectrum - relaible and secure
Well managed & secure Bandwidth
Uses existing networks infrastructure

Open standard
Industry Support - vendors investing

simply upgrading software without affecting
existing physical infrastructure
Commercial launch of NB-IoT in 2017
NB-IoT - 200Kbps
(25000 words/sec)
enough for IoT applications
Case study from the 3GPP
comparison for power and coverage
Past the +12dB coverage point, none of the methods can provide 10 years
Cannot get excellent coverage with low power (
Law of physics
coverage is gained by lowering the data rate

3GPP has specified three flavors of LPWA technologies
NB-IoT Market Potential
NB-IoT motivated analyst firms to create revenue forecast for 9 potential industries;
expected to uplift revenue of 334 million USD/year
NB-IoT Use-Cases
LPWA technologies comparison
Hardware developments
u-blox announces world's first
NB-IoT module
currently not available for sale
Sim for M2M - MFF
Emerging scenarios & challenges
Subscription Management Ecosystem for M2M sim
Light OS for M2M
More connected devices
IP4 not enough
up-gradation of existing connected devices to
Change operator over-the-air, after production
GSMA Remote SIM Provisioning
(for M2M)
Long term security solutions
Huawei LiteOS
enough length of secret key ?
Gus Vos - Chief Engineer @ Sierra Wireless
Joel Young - CTO @ Digi International
HUAWEI - NB-IoT white paper
Vodafone - NB-IoT
