Wireless transmission synchronization using a power line signal

摘要

A gateway may be configured to synchronize transmissions of a plurality of faulted circuit indicators (FCIs). The gateway may determine a time delay from a zero crossing of a power line signal and obtain network information from the at least one FCI from the plurality of FCIs. The gateway may identify a proximate FCI that is closest to a gateway based on at least one link parameter, and assign the determined time delay to the proximate FCI. The gateway may receive confirmations that at least one FCI received the determined time delay, and has synchronized transmissions based on the determined time delay and the zero crossings of the power signal.

1. A method for synchronizing transmissions of a plurality of faulted circuit indicators (FCIs), comprising:
determining a time delay from a zero crossing of a power line signal; obtaining network information from at least one FCI from the plurality of FCIs; identifying a proximate FCI, which is closest to a gateway based on at least one link parameter; assigning the determined time delay to the proximate FCI; and receiving confirmations that at least one FCI received the determined time delay, and has synchronized transmissions based on the determined time delay and the zero crossings of the power signal.
