3 Smart Metering – Smart Grid Spectrum resource is a key aspect of Smart Metering / Smart Grid standards TG28 work covers Various ENs govern spectrum access rules for a range of frequencies from 9kHz to 246GHz Our interests are primarily in lower layer communications Of particular interest is sub-GHz spectrum for good propagation in Smart Metering / Smart Grid environments Lower layer communications requirements are common in both Smart Metering and Smart Grid Require good propagation and building penetration Require low cost & low power implementations Low-medium data rates (10s to 100s kbps)
