• ITU reports that there were 5,373 million global mobile subscriptions in 2010

– this equates to 78% of the total world wide population

• 50 billion machines to be connected by year 2020

– this equates more than 7 times the global population

• Mobile operators around the globe desire a share in this vast M2M (Machine-to-

Machine) market

– Just seeking higher data rates will not create new revenue

Varying Requirements for M2M Applications• Different M2M applications have different set of requirements

• Consumer electronics require a single communication technology that can

satisfy a wide range of requirements

– Not desirable to have multiple technologies that only satisfy parts of the requirements

• Key Requirements for M2M applications;

– Mobility : Supporting higher mobility can also connect applications that are

stationary (e.g. mobile link for tablets can also connect stationary LCD TVs) stationary (e.g. mobile link for tablets can also connect stationary LCD TVs)

– Power : Lower power consumption can also work for applications that are mains

powered (e.g. low power link for headphones can also connect Home Theater Systems)

– Data Rate : Supporting high data rates can also connect applications that only

require low rates (e.g. high speed link for media server can also connect eReaders)

– Security : Supporting high security is beneficial for any application

– Cost : Lower cost is always better than higher cost

– Easy Use : Easy set up and usage is beneficial for any applications (Out of the box)

– Longevity : CEs can be kept by a consumer for more than 10 years

• Two basic types for communication: Wired and Wireless

• Mobility

– Some M2M applications inherently rely on wireless e.g. navigation, tablets etc.

• Ease of Deployment

– Wired installation difficult when wired infrastructure at consumer is variable

– Diversity of wired standards

• Robustness

– Wireless less prone to single points of failure (e.g. power outages)

• 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

PAN: Personal Area Network, LAN: Local Area Network, WAN: Wide Area Network

12

Characteristics of PAN/LAN vs. WAN

Characteristic PAN/LAN WAN

Data rates ZigBee : up to 250kbps

WiFi : 1Mbps - 600Mbps

GPRS: 10s of kbps

3G : 1Mbps - 14Mbps

LTE : 10Mbps - 300Mbps

Power Low power (~0dBm) Higher power (~24dBm)

Cost Less than $5 More than or approx. $10

Spectrum Unlicensed

e.g ISM bands, 868MHz, 910MHz,

2.5GHz

Licensed

e.g. 700MHz, 900MHz, 1.7GHz,

1.8GHz, 2.6GHz etc.

Topologies Star and mesh Star

Main standards ZigBee, WiFi, Bluetooth, ZWave,

KNX-RF

GPRS / GSM, UMTS, LTE,

WiMAX, CDMA, EV-DO

M2M related Standardisation Bodies

Aspect Standardization Bodies

Service ETSI, TIA, IETF (CoRE)

Access and Core Network 3GPP, 3GPP2, TISPAN, DSL forum, WiMAX forum

Gateway ETSI, IETF (6LoWPAN)

PAN/LAN ZigBee, WiFi, IETF (6LowPAN), KNX, ZWave , RFID

Smart Metering (vertical apps.) ISO, ANSI, CENELEC, IEC

• Various standards bodies working on M2M

– Some overlap, others focus on specific areas

– Market is expected to eventually decide

• From a CE manufacturer perspective, if a single unified approach covers a

wide range of application/requirements, the technology is preferred

• 3GPP has led the evolution of mobile telecommunication since its establishment in 1998

• Recently released LTE and LTE-A is now being rolled out and is expected to dominate the

mobile network in years to come, providing longevity similar to CE devices

• Current LTE will satisfy the requirements of highend CE device (e.g. LCD TVs) but may be

an over spec for others (e.g. portable audio player)

• To fill in this gap, an initiative to provide a low cost version of LTE has recently started

Possible Radio Approaches for Low Cost LTE

RF Chains / Antenna Ports

� Single antenna UE

� No receive diversity

� Affects sensitivity and coverage

� Removal of spatial processing

techniques

RAT Reduction

� Single LTE radio access technology

� Requires ubiquitous LTE adoption and

coverage

Half-Duplex Mode

� Already supported by 3GPP but not

widely implemented

� Remove duplexer

� Facilitates flexible band support

� Improves noise figure

Reduced Transmit Power

� Remove or simplify power amp stage

� Reduces power consumption

� Longer battery lifetime

� Coverage impact could be resolved using

additional network nodes

• Created low cost LTE together current full spec LTE would allow ubiquitous WAN

communication architecture suitable for a range of CE devices

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

network

• This would give confidence to CE manufacturers to implement this technology
