Machine-to-Machine Communications
Machine-to-Machine (M2M) communications refer to the exchange of data between devices:
· With minimal human intervention,
· Controlling and monitoring applications.

M2M – Some Related terms
Machine-Type Communications (MTC) • Communication where at least one element is a Machine.• Working terminology used by 3GPP.• Regarded M2M carried over cellular networks.
Internet of Things (IoT)• Includes connection and access to the broader Internet.• First coined in 1999 by K. Ashton to describe a “world of
seamless connected devices that would save us time and money”.
Cellular IoT (CIoT)• Wireless networks operating in licensed spectrum.• Developed for IoT purposes.

Connectivity Networks
6From “M2M in Smart Grids & Smart Cities Technologies, Standards, and Applications”, Mischa Dohler and Jesús Alonso-Zárate
Wired – cabling between devices and gateways:- Pros: reliable, high data rates, secure, little delays.- Cons: expensive, not scalable, no mobility.
Wireless Capillary – shared shor t-range network:- Pros: cheap, scalable, low power.- Cons: low data rates, interference, lack of ubiquitous coverage.
Wireless Cellular – dedicated cellular link:- Pros: excellent coverage, mobility, roaming, secure.- Cons: expensive operation and maintenance, energy efficient.

Applicability
From connectivity to service -oriented
10
MTC is about connected devices to serve specific purposes.• Combination of products and services.Focus should be on the experience and value co-creation.• Rather than the development of products.• The focus is on “what problems can you solve”.
Connected products … or services?

Transportation
12
• Smart Parking.• Car sharing.• Pay-as-you-drive Insurance.• Automatic maintenance scheduling.• Self-driving vehicles.
Health & Wellbeing
13
• Real-time symptoms report.• Report for medicine intake.• Remote patient monitoring.
Smart Cities
14
• Smart bin collection.• Dynamic traffic lighting.• Building Automation.• Smart lights.• Utility metering.
Industrial Automation
15
• Smart Grids.• Manufacturing automation.• Telemetry.• Industry 4.0.
M2M Characteristics
• Huge amount of devices• Need for Interoperability• Autonomous operation • Mainly uplink data to repor t sensed information• Small data transmissions, on/off or readings from meters• Duty cycling to repor t information• For many applications, mobility is not a major concern• Heterogeneity in terms of information priority• Energy efficiency and network lifetime
16
M2M and the Forecasts
17
• M2M is not about high traffic, but high number of devices transmitting small payloads.• M2M dimensioning limited by signaling rather than capacity.

Technical Challenges
18
Specific Requirements
• Reduce mobility signaling.• Time controlled transmissions.• Small data transmissions.• Interoperability.• Priority Alarm Handling.
There is a need to
• Provide connectivity to large number of devices
• Prevent traffic peaks: congestion control.
• Energy-efficient mechanism for autonomous devices.
• Provide charging mechanisms suitable for M2M.
Business Challenges
19
Existing solutions are typically dedicated to single applications.Business model focused on provider-customer model.Interoperability between M2M products vendors and networks.Difficulties to analyse value.
20
Cases• Phone Keys• Remote Monitoring• Facility Management• Connected cars
21
• Digital key using mobile phones.• Access authorization and time registration.• Homecare authorities can prove service delivery.• Relatives can monitor who enters the home.
• Big values:– Reducing complexity in keys management – Providing accurate reporting times

#1 Homecare - Access Control and Time Reporting
ShowstoppersMNO in charge of the application management phased out the service, claiming:• Small market• Lack of suitable phones• Complex product for the sales force• Long sales cycles in the public sector
22Source: Jan I Markendahl “Mobile Network Operators and Cooperation :A Tele-Economic Study of Infrastructure sharing and Mobile Payment Services”. 2011 KTH PhD dissertation.
Change:Service was not cancelled, delivered without active participation of MNOs, the municipality took care of the connectivity provisioning.
#2 Remote monitoring - in Västerås
23
• Caretakers need assistance several times per day• Some visits can be replaced by video conversation
– Check medication intake.– Reminders.– First contact in case of alarms.
• Big values:– 300 e-home care customers.– 2 M€ annual cost saving.– Immediate response.

InitialSetbacks
24
• Less than 30% of people of age above 70 had Internet. • For the ISPs, the service was for :
– A small, price sensitive market segment.– Customers that require a lot of customer care.
• Customers mistrusted the ISP installation.
New Thinking• Customers do not pay for broadband.
• Installation done by homecare staff.
• The town IT service department:
– Buys broadband connectivity capacity.
– Acts as service provider.
– Is responsible for the technical solution.

#3 Facility Management - Halmstad town
25
• Parallel applications are present
• Provided with vertical solutions:
• Network deployment and operation.
• Connectivity.
• Billing.
• Customer relationship.
• Our services should be provided by our infrastructure.
• Providers want to control the customer interface.
26
The proposed solution was a horizontal and shared infrastructure.This common infrastructure is operated by a neutral actor.
#4 Connected Cars
Two cases: • Tesla Motors and the Tesla Model S. • Ericsson’s “Connected Vehicle Cloud” used by Volvo.
• New value added services:• Either by themselves.• Or through third-par ty actors.
• Gather valuable data on the operation of the car,• The drivers gain access to new services.• Single delivery channel for third-par ty actors.
27
28
• Main partner is Ericsson, and the M2M Service Enablement Platform.• Horizontal platform for applications and developers. • Connectivity becomes a challenge.
• Initial phase via the user’s smartphone (roaming fees).
CustomerCustomer
• Main partners are operators (TeliaSonera/AT&T).• Silo approach restricts the applications by third-party actors.• Solves the connectivity problem
• Ensures seamless service while roaming.
M2M services are often par t of a complex value constellation. Consumer not directly involved with communication provider
