LTE for meters & sensors ? › Are LTE devices simple? – high requirements on M2M device › Are LTE devices well reachable? – MTC devices may have unfavorable attenuation (basements, metal enclosures) – stationary MTC devices affected in particular › Does LTE enable M2M devices to operate on battery for multiple years? – not really referring to LTE Release 8 with regard to the defined M2M requirements Commercial in confidence | 2014-01-23 | Page 13

Addressing Limitations COST COVERAGE Reducing cost by up to 80%, eg by Options for low-rate MTC devices – repetition with energy accumulation – one receive antenna – power/PSD boosting – data rates limited to 1 Mb/s – relaxed performance requirements – using 1.4 MHz BW only – simplification/elimination of physical control channel functionality or Further enhancements design of new channels/signals – half-duplex FDD – reduced RF bandwidth Commercial in confidence | 2014-01-23 | Page 14
