Description
以下、本発明の実施例について図面を用いて詳細に説明する。図1は、本発明に係る無線端末制御方法の実施例を説明するための説明図である。本実施例では、地域10を網羅する無線ネットワークを構築するにあたり、複数の無線LANの各基地局となるAP11〜19を図1に示すように配置する。AP11〜19は、有線LANにより相互に通信可能に接続されている。AP11〜19を基地局とする各無線LANは、その物理層の通信として、スペクトラム直接拡散方式(DSSS)を用いる従来知られたIEEE802.11bが適用されている。
11〜19 基地局(AP)
11A〜19A 通信エリア
101〜124 無線端末(CL)
Claims (2)
- スペクトラム直接拡散方式を用いた複数の無線LANが設けられたエリアにおいて各無線LANの基地局が自局に接続する無線端末を制御する方法であって、
各無線LANの基地局が、他局の通信チャネルと当該他局に対する自局の受信レベルとを収集し、該収集した受信レベルに基づき自局の通信エリアに重複する通信エリアを持つ他局の有無を検査し、該検査により複数の他局が検出されたとき当該他局の中から相互の通信チャネル間隔が所定値未満である各他局を検出し、当該各他局に電波干渉に関する通知を行い、
前記電波干渉に関する通知を受けた各基地局が、自局に接続する複数の無線端末に対し送信電力の低減を指示することを特徴とする無線端末制御方法。 - 前記各基地局が前記各無線端末に送信電力の低減を指示するとき、当該各基地局は、予め設定した特定の送信電力のレベルを各無線端末に通知することを特徴とする請求項1記載の無線端末制御方法。
