Introduction

• As we transition from traditional Grid to Smart
  Grid and on to Smart Microgrids, our dependence
  on high performance and reliable wireless
  communication increases.
• Connectivity and Coexistence can not be taken for
  granted.
• We must re-examine the assumptions upon which
  both government policy and industry practice are
  based.
• The variety of scenarios encountered in SG and
  SMG propagation environments
• Increases the risk of under/over design
• Risks the proper functionality of the network
• Increases the risk of unexpected or unwarranted
  expenses
• Our goal is to reduce the risk of poor design by
  developing models that capture our knowledge and
  understanding of propagation impairments in a
  form useful in simulation and design.

Selected Project Highlight SRSP 301.7 Revision

• Are technical requirements for terminal station
  fixed P2MP radio systems used for the management
  of the electricity supply in Canada too
  restrictive?
• Minimum gain of 12 dBi, maximum 3dB beam width of
  30o
• Key considerations
• NLOS multipath propagation environment
• Relatively low capacity systems
• Omnidirectional or Directional terminal antennas?
• Impacts of Using Omni for P2MP deployments
• Co-channel Interference, Coverage, ASE
• Second best server redundancy
• Cost of installation and maintenance
• More details in our poster

Selected Project Highlight Link Budget Problem
on Relay Nodes - Shadow Fading Characterization

• Shadow fading on Relay Nodes at 1.8GHz Macrocell
  environment Demonstration that shadow fading at
  pole-top relay nodes is worse than previously
  realized and must be accounted for in design.
• Effect on network coverage.
• Shadow fading at higher frequencies for advanced
  networks.

Selected Project Highlight Characterizing
Coexistence Between Radios at Relay Nodes

• The objective is to devise and execute a test
  methodology to recognize the source of
  interference and a new method to investigate
  potential coexistence issues between the
  collocated 915 MHz SMI, 1.9 GHz 3G and 1.8 GHz
  WiMAX transceivers.
• Applicable to both SmartGrid and Smart Microgrid
  networks
