IntroductionIntroduction

In M2M communication, objects can talk to each other without human intervention

Today there is insufficient integration of real physical world with virtual world (computers, servers, etc)

Today Human translates physical world information in to digital world information to use computers

What is M2M? What is M2M?

M2M refers to technologies that allow both wireless and wired systems to communicate with other devices of the same type.

4 basic stages that are common to just about every M2M application

1) Collection of data

2) Transmission of selected data through a communication network

3) Assessment of the data

4) Response to the available information

Works? Works?

One can buy soft drinks, flowers, etc from vending machine in self service manner

Once the vending machine detects the item in out-of-stock, it sends message to order

management server through 3G/4G communication link which further send

information to vendorThe vendor re-stocks the vending machineVending machine stores daily sales data in internal database and sends information to

vendorVendor will know which product has been

sold and the total daily revenue

M2M Network/App DomainM2M Network/App DomainNetwork Service Capabilities

-Provide functions that are shared by different applications

-Expose functionalities through a set of open interfaces

-Use Core Network functionalities and simplify and optimize applications development and deployment whilst hiding network specificities to applications

-Examples include: data storage and aggregation, uni-cast and multi-cast message delivery, etc.

M2M Applications (Server)

Applications that run the service logic and use service capabilities accessible via open interfaces.

M2M Device DomainM2M Device Domain

* M2M Device

– A device that runs application(s) using M2M capabilities and network domain functions. An M2M Device is either connected straight to an Access Network or interfaced to M2M Gateways via an M2M Area Network.

*M2M Area Network -A M2M Area Network provides connectivity between M2M

Devices and M2M Gateways. Examples of M2M Area Networks include: Personal Area Network technologies such as IEEE 802.15, SRD, UWB, Zigbee, Bluetooth, etc or local networks such as PLC, M-BUS, Wireless M-BUS.

*M2M Gateways -Equipments using M2M Capabilities to ensure M2M Devices

interworking and interconnection to the Network and Application Domain. The M2M Gateway may also run M2M applications.

M2M Market CharacteristicsM2M Market Characteristics

Initial investment is difficult (e.g., license fees)

Complex supply chain: from chipset to network to mobile operators

Long-tail business

Low ARPU (<$10) compared to voice (<$30)

Lagging standards

ConclusionConclusion

- M2M related technologies are in place and the market has massive potential for growth

- Standardization is essential for long term development of the technology and for interoperability of networks and services

- Operators, integrators and vendors have expressed the need to standardize end to end M2M

- Regulation in Europe, USA and Asia is pushing for a standards based solution

- It is essential to have globally compatible standards
