Utility Wireless Applications• Support the management of power delivery system– Monitoring, protection and control1.8 GHzAirlink2
Utility Wireless Application Needs• Utilities need ubiquitous overage over their infrastructure areas.– Power generation plants and substations are not always in areas with high population.– Distribution grids don’t always follow main traffic routes.– Wireless provides cost effective coverage, complimentary to wireline.• Reliability is non-negotiable.– Regardless of the environment, society expects utilities to work.– Infrastructure management needs the ability to monitor, control and forecast the usage.– The communications network needs to be stable and predictable.• Security– Must be able to trust the network.– No network disruption.• Integration and support of the existing infrastructure.– Utilities have a variety of different and legacy technologies which continue to be reliable.– Upgrades and changes have to be evolutionary not revolutionary• Support of smart metering.– Enable more efficient use of energy resources.• Mainly fixed and nomadic modes of operation.• The majority of the information is from the distribution, so UL biased.• Corrective action needs to be fast to minimise any shutdown.– Low latency.– Systems need to work when cutoff from the main network.3
