 Billions of M2M devices by 2020 (Ericsson-2011)
 ICT: 3% - 6% Carbon Emission globally and growth
rate of 16% - 20% (Ashok et al, 2013)
 ICT: 25% - 60% power consumption in buildings
(Richard et al)
 Global warming

9. The Band and Range Relationship of Sub 1GHz

10. Conclusion
The Sub 1GHz spectra provide sufficient access,
cheap, and energy efficient communications
medium that can be harness for M2M
communications. The marriage of the sub 1GHz
cellular and other short range standards is
needed to be able to accommodate all the
M2M devices and applications.
