The Era of “Internet of Things”• M2M is known as machine-to-machine/man/mobile
Communication involves one or more entities that do not necessarily need human interaction Human unaware communications
• From 6 billion people to 50 billion machines

M2M- The Future of Communications• Incubation phase
A few small M2M Apps in the existing network
• Take-off phaseWith more M2M device/traffic, there is a need to update/ optimize the network for M2M applications.
• Explosion phase M2M device/traffic becomes far beyond that of H2HThe network should be designed for M2M

Messages from Huawei Management• From CEO – Mr. Ren, Zhengfei
We foresee broad market development opportunities in mobile and home broadband networks, fixed mobile convergence, business operation support systems and smart devices.
• From Chairman of the Board – Ms. Sun, YafangNew businesses, represented by the "Internet of Things", mobile broadband, cloud computing and home networks, will lead us into an exciting new decade.
As telecom markets become saturated, the telecom industry will evolve from connecting people to connecting machines.

M2M Opportunities over CDMA
• Never take “One-Size Fits All” approach for M2M Apps.• Choose the right applications and right model that CDMA
(WAN) presents an edge over other accesses.• Adopt Tiered Network Architecture for M2M
Leverage the features of different access in lower tier• CDMA (WAN) Advantages:
Matured and worldwide deployed networks (ready to use)Full mobility, roaming, flexible data-rate, reliable RAN Network management and security mechanism availableFull global standard support
3GPP2, TIA, IETF, OMA, ITU and others
• Need High-Value-Added Applications to kick-off M2M.

• CDMA is a clear winner for Mobility required M2M Apps
• CDMA can work with other Access Technologies through Tiered Network Structure for Efficiency and Cost-Effectiveness

M2M Challenges over CDMA
• Cost of the CDMA ModulesChipset cost is higher than chipsets for other accesses.In short-term, may be justified by high-value-added applications.
• Network Efficiency due to the use of M2M DevicesIs the user behavior of M2M devices really much different than smartphone users?
• Operators: Data-pipe vs. Walled Garden• Need Large Scale Value-Added M2M Services
Silos of Small M2M Applications• Regulatory, Liability, Personal Concerns (Privacy)
Page 12
Standard efforts to solve efficiency and application interworking, regulatory and publicity issues - For example, through 3GPP2, TIA TR50.1, CDG
HUAWEI TECHNOLOGIES CO., LTD.
Time for Action
• Too many talks, Too much worry, Too few actions• Network Congestion will be an issue for M2M only if the
usage builds up• Network Efficiency issues can be addressed through
standardization efforts from the CDMA community• Cost-Effectiveness on CDMA M2M devices depends on the
volume• M2M Applications can be integrated through standardization• Operators can be great M2M Service Providers
Credibility, Service Management Experience, Marketing, Distribution Channels, Field Deployment and Services, Financial Supports, Government and Industrial Relations
• Paradigm shift from H2H to M2M takes time.
