M2M and Consumer Electronics

• M2M communication is important to Sony as a consumer electronics

manufacturer

– We expect that all of our consumer electronic products could potentially

incorporate some sort of M2M communication technology in the near future

• The current study in 3GPP on creating a lower cost version of LTE would • The current study in 3GPP on creating a lower cost version of LTE would

enable the entire M2M CE eco-system be built upon a single wireless

communication technology

Varying Requirements for M2M CE Communication

• Different M2M CE applications have different requirements

• For wide deployment and success, M2M CE communication requires one single

communications technology that can satisfy a wide range of requirements

– Not desirable to have multiple communications technologies that only satisfy

parts of the requirements, can not pile on extensive number of wireless techs

• Key Requirements for M2M CE Communication; Ubiquitous Connectivity, Cost, Ease

of Use, Longevity, Security

• Is there a single communication technology that can encompass all of the varying

M2M CE Requirements??

• Two main types for commercial wireless communication: PAN/LAN and WAN

• Wireless PAN/LAN technologies for M2M can cause;

– Coverage Holes : no control over which PAN/LAN deployed at consumer’s location

– Difficult Setup : not easy for some consumers to set up own PAN/LAN networks

– Security Risk : networks set up by consumers may not be secure

• LTE is now being rolled out (LTE-A later, also) and is expected to dominate in

future, providing longevity similar to CE devices

• Current LTE will satisfy the requirements of high-end CE devices (e.g. LCD TVs) but

may be an over spec for others (e.g. portable audio player and other M2M

applications)

• To fill in this gap, an initiative to provide a low cost version of LTE is underway in

3GPP

How to Achieve Low Cost LTE

• 3GPP has studied the cost of each component in an LTE modem and

evaluated methods to reduce them

• Identified approaches

– Reduction of Bandwidth

• Less computational effort

– Hardware simplification

Up to 59% Cost Reduction of LTE Modem was identified by utilizing above techniquesUp to 59% Cost Reduction of LTE Modem was identified by utilizing above techniques

– Hardware simplification

• Just one receive hardware chain

• No simultaneous transmit and receive

– Reduction of Transmit Power

• Fewer hardware stages and/or cheaper hardware

– Reduction of Peak Rate

• Less computational effort and cheaper hardware


Reduced Bandwidth

Coverage Enhancement Low Cost LTE

• Coverage requirement may be more stringent

for M2M CE than conventional H2H

communication

– Some M2M CE can not be moved easily

– e.g. need to connect to TV in a basement

• 3GPP will investigate ways to enhance low • 3GPP will investigate ways to enhance low

cost LTE so that it can provide required

coverage for M2M Devices

• Potential methods may be;

– Repetition

– Increased transmission power/antenna

– Stronger coding

– More nodes

– etc.

• Creating low cost LTE together with current full spec LTE could allow

ubiquitous WAN communication architecture suitable for a wide range of

CE devices

– Low cost LTE devices and full spec LTE devices can coexist within the same

network

• This would give confidence to CE manufacturers to implement M2M LTE
