  1. 1. Sub 1GHz M2M Communications Standardization: The Advancement in White Space Utilization for Enhancing the Energy Efficiency By Sylvester Ajah
  2. 2. Discussion Points  Introduction  M2M Applications  Why M2M Energy Efficiency  Energy Efficient Principles  M2M Standardization Networks  Potential Sub 1GHz M2M Networks Properties  The Band and Range Relationship of Sub 1GHz  Conclusion  Summary  References
  3. 3. Introduction • M2M – The independent communications between the electronic devices Mischa D. et al, 2010
  4. 4. Applications M2M Application s Building s Industrial Transportati on RetailSecurity IT / Networks Healthcar e
  5. 5. Why M2M Energy Efficiency  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

Sub 1GHz Networks Sub 1GHz Standard /Properties Weightless IEEE 802.22 IEEE 802.11af IEEE 802.11ah IEEE 802.15.4 Frequency (MHz) 470 – 790 54 – 862 470 - 790 755 - 928 868, 915 Maximum Range (KM) 10 30 1 0.075 Maximum Downlink Throughput (Mbps) 16 18 18.1 6 0.04 Uplink Throughput (Mbps) 0.5 0.384 - 0.14 - Structure Cellular Cellular White -Wi- Fi Wi-Fi - like Star, Mesh Bandwidths (MHz) 6, 7, 8 6, 7, 8 - 1 - 8 2 Proposed Application M2M Communications / internet of things Wireless broadband in rural and remote areas - Wireless sensor network Wireless Sensor Network
  9. 9. The Band and Range Relationship of Sub 1GHz
  10. 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.
