摘要
Methods and systems for providing accurate time-keeping on battery-powered communication devices used in AMI systems, mesh networks, and multi-channel radio networks. One embodiment allows the use of low power (and low cost) crystals in battery-powered endpoints by periodically correcting the poor timing of these crystals using communications with a nearby, non-battery-powered device. Such communications allow the battery-powered devices to align their timing with that of their non-battery neighbors, among other things.
