Consumer devices IoT devices
Distributed deployments
in rural areas create
additional demand
in areas with less
infrastructure.
Devices connect on a
best-effort basis.
Consumers accept
the limitations.
Devices use more
data less frequently.
Mission critical IoT
applications require
real-time feedback
greater demand for
more robust systems
with lower latency.
IoT devices generate
traffic with different
patterns.
Often small, regular
data use (e.g. a network ping).
Devices are generally
located in populated
areas (cities, towns etc.)
Most cell towers are
located in these areas.

When we think of the IoT,
we often think of the more
consumer focused smart
home applications,
connected fridges,
alarm systems etc.
But many IoT applications
are located much further
afield.

Multi-IMSI:
Multiple independent
core networks on the
same SIM
Open connectivity
is the answer,
the connectivity
needs to enable
remote control
and back-up
Cellular applications
should avoid
dependency
on any one
connectivity
provider
Open application on
the SIM to swap
between core
networks automatically
if connection is lost
Avoids dependency
on one network
infrastructure and
provides a “No Single
Point of Failure” solution
Platform to enable

profile
New IMSIs can be
added OTA to respond
to changing market
conditions (pricing,
roaming agreements...)
Future proofs
connectivity as the
profile of the SIM can
be adapted remotely
Remote
device
requirements
Remote and roaming devices
are difficult to troubleshoot or
maintain.
They must be designed to allow
remote updates to avoid costly
truck rolls and downtime.
Allow interaction with different
types of cellular connectivity via
the SIM card (multi-network,
multi-IMSI)
Devices should include
an STK (SIM Application
Toolkit) and ability to use
multi-IMSI SIMs and receive
OTA messages for remote
configuration
The printed
circuit board
design should
be compatible
with 3G and
4G modems
even if the
current
requirement
is only for a
2G modem.
The modem should be compatible
with with different connectivity
options. For example, non-steered
multi-network SIMs are key
to avoiding coverage
blackspots. To keep connectivity costs
to a minimum,
session lengths must be
optimized to allow for data
billing increments.
Must accept the
correct AT
commands
OTA to ensure
that SIMs can
be updated
when market
conditions
change.
Since devices cannot be easily
accessed and re-configured,
they should avoid dependency
on any one network.
The connectivity should
be remotely controlled
and access to multiple
independent operators
is paramount.

MNOs MVNOs
Due to the roaming
agreements they
have in place, tend to
steer data to specific
networks, which may
not be beneficial in
terms of coverage.
Do not generally have
the knowledge of
individual sectors to
allow them to make
recommendations
in terms of hardware,
firmware or software
development.
Cannot guarantee
uptime 100% of the time,
network outages can
and do happen, which
can be disastrous for
mission critical
IoT applications
Are independent, so they
can make agreements
with individual networks
around the world
Can layer networks on top
of one another to provide
redundancy and back-up
in case of technical or
commercial issues
Have a greater
understanding of
the vertical sectors
in which many of
these applications work
and the way devices,
firmware, software
need to be configured
Many MVNOs are now
adding their own virtual
infrastructure, software
and platforms on top of
the network connectivity,
providing more control and
future proofing e.g. virtual HLR,
multi-IMSI applications on
the SIM, OTA platform
for remote control
Which connectivity partner can provide
the best options for future-proofing?
Have their own
infrastructure,
but in terms of
the IoT this can
be restrictive
since this has
been developed
initially to service
consumer demands
The IoT is everywhere...

Connectivity Options
Cellular connectivity offers
many advantages for remote,
roaming and mission critical applications
1- Global nature of cellular infrastructure
2- Defined standards for 2G, 3G, 4G
3- Multi-Network and roaming capability
4- Rapid throughput of data for real
time applications
5- Future 3GPP standards (Cat 1,
Cat M, NB-IoT) will offer optimized,
lower cost connectivity for IoT
Networks are not
currently designed
to support the
growth in traffic
forecasted for
the IoT
Networks have traditionally been designed to manage
mobile traffic from consumer devices. IoT devices put
very different demands on the network
