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) 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 Technology that encompasses more requirements is desired for CE 9

Wired vs. Wireless Communication Wired Communication Wireless Communication 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) Wireless communication technology is better suited for many M2M applications 11
Wireless PAN/LAN vs. WAN M2M with PAN/LAN M2M with WAN 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.gism bands, 868MHz, 910MHz, 2.5GHz Topologies Star and mesh Star Licensed e.g.700mhz, 900MHz, 1.7GHz, 1.8GHz, 2.6GHz etc. Main standards ZigBee,WiFi,Bluetooth, ZWave, KNX-RF GPRS/ GSM, UMTS, LTE, WiMAX, CDMA, EV-DO Power consumption and cost are the key drawbacks of WAN technology for M2M 13

M2M related Standardisation Bodies Aspect Service Access and Core Network Gateway PAN/LAN Standardization Bodies ETSI, TIA, IETF(CoRE) 3GPP, 3GPP2, TISPAN, DSL forum, WiMAX forum ETSI, IETF(6LoWPAN) 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 LTE and its low cost enhancements is expected to be the key enabler for M2M 15
