1. A network system comprising at least two base stations for establishing wireless connection to wireless terminals, the base stations being connected via at least one cable with each other, wherein:
- when one of the base stations, or an interfered base station detects interference with another one of the base stations, or source base station, the interfered base station informs the source base station of the occurrence of the interference via the cable; and
the source base station controls its power to send radio waves in response to the information.

Abstract
Base stations for establishing wireless connection with wireless terminals are connected with each other via cables. When one of the base stations detects interference with another one of the base stations, the interfered station informs the source station of the occurrence of the interference via the cables. In response to the information, the source station lowers power to send radio waves in order to avoid the interference. If the interference disappears, then the source station recovers the power.

9. A base station comprising a wireless interface circuit for establishing wireless connection with a wireless terminal and wired interface circuit for establishing wired connection with another base station, comprising the circuits for:
-
detecting interference with a first base station;
generating interference information for informing the first base station of occurrence of interference to send the interference information to the first base station via the wired interface circuit;
detecting interference information which is generated by a second base station and is received via the wired interface circuit; and
controlling power to send radio waves in response to the interference information generated by the second base station. - View Dependent Claims (10, 11, 12)
