Claim Text:
1. A smart metering system, comprising: a band search sensor which is installed in a predefined area and configured to scan a digital public broadcast channel band; a band management server configured to manage area-specific broadcast channel status information based on a scanning result obtained by the band search sensor and to search a white space band that is an idle channel band of a corresponding area based on the broadcast channel status information to allocate the white space band as a smart metering data transmission channel; and a base station configured to allocate the smart metering data transmission channel from the band management server and to form a wireless communication channel between a smart meter and a grid central server via the allocated smart metering data transmission channel, wherein the idle channel band is a band that is not allocated to a broadcast provider in the corresponding area, wherein the band management server is further configured to determine whether the digital public broadcast channel overlaps with the allocated smart metering data transmission channel, and wherein the base station is further configured to reallocate the smart metering data transmission channel when the allocated smart metering data transmission channel is determined as overlapping with the digital public broadcast channel.
