Remote meter reading communication terminal and remote meter reading communication system

摘要

In the present invention, a pattern storage unit stores, in advance, a signal generation pattern, which is defined by the Radio Act, for communications carried out in a frequency band used by a transmitting and receiving unit. The signal generation pattern: is a legal pattern that defines the time length of a permission period during which the transmission of radio signals is permitted, and of a prohibition period during which the transmission of radio signals is prohibited; and is configured by alternately repeating between the permission period and the prohibition period. An interference wave determination unit determines that an interference wave received by the transmitting and receiving unit is due to communication based on the Radio Act when the generation pattern of the interference wave matches the legal pattern, and determines that the interference wave received by the transmitting and receiving unit is not due to communication based on the Radio Act when the generation pattern of the interference wave does not match the legal pattern.
