  1. Wireless Networks and Services 10 Years Down the Road Ross Murch Professor, Electronic and Computer Engineering Director, Centre for Wireless Information Technology

  2. Internet Voice Video WiFi Email SMS Mobile TV Today- 2009 Yesterday- 1999 Billions of wireless devices Millions of wireless devices Wireless Revolution

  3. Medical applications Distributed Environmental & Bio Sensing Next generation phones Various Info/Media Security New Mobile Devices Smart RFID People to People People to machines Machines to Machines Tomorrow- 2019 Trillions of Wireless devices Wireless Everywhere

  4. Interference Limited Spectrum Trillions of Wireless Devices Seamless Access Power Consumption System on Chip Design Challenges

  5. What is Next for Wireless Communications? • In broadband access WiMAX and LTE promise extremely high peak rates • However this is just for one user in one cell • What happens when we have Trillions of users • Wireless aggregated capacity will need to increase enormously • How can this challenge be met?

  6. Increasing Capacity • What can we do? Increase Power Cooperative systems Increase Bandwidth Cognitive Radio More Channels MIMO

  7. MIMO- Large M • Capacity linear in the number of antennas • Makes sense to make N as large as possible • Instead of 2 antennas lets use many- 36 or even 100 • Chi Yuk Chiu and , RD. Murch, 24-Port and 36-Port Antenna Cubes suitable for MIMO Wireless Communications, IEEE Transactions Antennas and Propagation, Vol 56, No 4, pp1170-1176, April 2008

  8. Deployment Scenario WRAN Base Station Wireless MIC TV Transmitter WRAN Base Station WRAN Repeater Typical ~33km Max. 100km Wireless MIC : WRAN Base Station : CPE Cognitive Radio- IEEE 802.22 (WRAN)

  9. Cooperation Cooperative Networks • Cooperation between nodes • multi-user encoding and decoding • relays may exchange information with each other in order to coordinate transmission and reduce interference [GastparVetterli02]

  10. What is Next for Wireless Communications? Mobile Computing Embedded Wireless Devices Ubiquitous Computing and Access Multifunction devices and services Agents and Assistants Pervasive Communications

  12. Pervasive Communications • Trillions of mobile wireless devices • Devices ubiquitously embedded in the world • actuators, sensors, memory, processing, speakers, microphones, cameras, displays • Intelligent software agents deployed • To mine data, act on that data, observe trends, and adapt to their environment • Easy configuration and maintenance • The Internet will become essentially a pervasive global system • What the internet has done for computers, pervasive communications will do for wireless

  13. Easy Configuration and Maintenance • Intelligent software agents could be deployed across the network whose function it will be to • Mine data • Act on that data • Observe trends • Carry out tasks dynamically • Adapt to their environment

  14. Pushing the Wireless Revolution • Revolution in short range wireless communications • WLAN, WiFi, IEEE 802.11a/b/g/n • Rates up to 54Mbps • IEEE 802.11n using MIMO • Approx 250Mbps • Zigbee • Bluetooth • UltraWideBand • 3.1-10.6GHz band • IEEE 802.15.3a • 480Mbps within 1-10m • RFID • Passive • UHF- 900MHz

  15. Application Presentation Application Session Presentation Session Transport Transport Network Data Link Network Physical Data Link Physical Convergence • Divergence of Physical layers and Applications

  16. More Breakthroughs Needed… • Aggregate Wireless Capacity Evolution • Fundamentally limited using conventional techniques • Cost and Energy • Cognitive Radio • Cooperative Systems • MIMO • Efficient protocols • Adaptation • Pervasive Communications Revolution • Automatic configuration- self configuring • Dynamic processing, prediction and actions- agents • Energy conservation • Miniaturization

  17. Medical applications Distributed Environmental & Bio Sensing Next generation phones Various Info/Media Security New Mobile Devices Smart RFID People to People People to machines Machines to Machines Tomorrow Trillions of Wireless devices Wireless Everywhere
