Data rate

Alternatives for M2M Communications

Wired: Cable, xDSL, optical •  High reliability •  High rate •  Small delay •  Not cost effective •  Lack of scalability •  Lack of mobility

Wireless capillary: WLAN, Zigbee, IEEE 802.15.4x •  Less expensive •  Generally scalable •  Low power •  Weak security •  Interference •  Lack of universal infrastructure

Cellular: 2G, 3G, 4G, 5G •  Ubiquitous coverage •  Mobility •  Roaming •  Security

4G Extensions for M2M

LTE-Release 11 •  Overload control

•  Use Extended Access Barring in overload

LTE-Release 12 •  New lower device category:

Cat-0 •  Complexity reduction •  Elementary power savings

LTE-Release 13 •  LTE MTC: Further reduced

category •  New, simpler device •  Significant power savings •  Enhanced coverage

Global M2M Mobile Devices

q  2G currently preferred q  Lower device cost q  Greater geographic coverage q  Longer battery lifetime than 3G

and 4G q  Low data rate

q  Low Power Wide Area

(LPWA) q  High coverage q  Very low cost connectivity q  Very low data rate q  Long battery life q  Neul, Sigfox, OnRamp

Coverage and cost of LTE MTC not enough
