Billions of devices

Ericsson: 50 billion devices by 2020
eCall: 14 million cars per year
Energy: 10bn sockets in North America
Nike+ shoe
Smart meters, grids, cities, dykes
Multiple communication modules per
device? e.g. for a car?

2G/3G/4G and WPAN for M2M
• Not one clear winner
• WPAN best for in and around the home
– How to connect to a gateway to internet?
• 2G/3G/4G best for dispersed applications
– Near global coverage
– SIM based zero configuration authentication
• Policy implications in use of 2G/3G/4G
Impact on business models
• The consumer is not the user
• A company or government is M2M user
– Controls parameters for millions of devices
– Needs to contract connectivity for device
• Change from one user, one phone to one
one user, million phones.
• M2M user have different requirements
– Businesses are responding to some
Business requirements
Business requirements difficult to fulfil:
– Switch mobile networks without SIM swap
• Logistics of switching 10,000 SIMs is a nightmare
– National roaming to avoid dark spots and
failure
– Negotiate roaming with local operators
• Gives small operators a chance of M2M contract
– Seamless access to home gateways
– Guarantees on life time of network (30 years)
A SIMple piece of plastic?
• SIM-card locks M2M-user to network
• If M2M users could be MVNO with own
SIM-cards, they could roam and switch
• Only public service providers have access
to IMSI-numbers for SIM-cards
• One option is to liberalise market and give
private networks access to IMSI-numbers
– See Logica for Dutch Ministry of Economic
Affairs – Flexibel gebruik MNC’s
How?
• Get IMSI from regulator
• Outsource platform and HLR (like telco’s)
• Contract telcos in each country
– It’s easiest if you need only one country
– Great opportunity for intermediairies
• Contract with broadband networks for
access to wifi?
– New, but standards exist
Precedents
• Everyone can get a block of IP-addresses
and Autonomous System Number
– Allows Googles and Amazons to appear
– AS42848 is European Commission
• Dutch Ministry of Defense has own IMSI’s
• UK and NL allow private organisations to
use GSM in unlicensed DECT-guard band
Technical solution not enough
• Over the Air update of SIM with new IMSI
and crypto keys
• Work on industry standard started this
year under pressure of Apple
• Control lies with telco for all parameters
• Doesn’t solve all business problems

Other policy problems with M2M
•
•
•
•
Numbering (enough phone numbers?)
Privacy (think TomTom)
Sharing public/private sector information
Frequency policy (M2M will lock in
frequencies for 30 years?)
Conclusion
• M2M changes the market, with a new user
emerging: The million device user
• This user is currently locked in and can’t
directly get access to numbers
• One option may be liberalising the market.
• M2M user will probably use own SIM with
own IMSI with OTA possibility
– In case of case of acquisition or selling of part
of business, SIMs can be updated
