Abstract
Description
図1は、本実施の形態に係る基地局システムの外部構成例及び設置例を示す外観斜視図である。図2は、本実施の形態に係る基地局システムの内部構成例および接続関係を示すブロック図である。
実施の形態1では、通信ケーブル接続端子13とは別の電源ケーブル接続端子14を介して、基地局装置1が外部電源から給電を受ける具体例を示した。しかしながら、基地局装置1は、無線伝送装置2と同様に、データ転送装置3から通信ケーブル41を用いて供給される電力によって動作してもよい。この電力供給は、例えば、PoE(Power over Ethernet)により行えばよい。より具体的に述べると、図3に示すように、データ転送装置3の電源機器36は、通信ケーブル42に直流電圧(e.g. -48V)を供給する。そして、基地局装置1の電源機器16は、通信ケーブル41を用いて供給される直流電圧(e.g. -48V)を受電し、電子機器11に動作電力を供給する。このような構成によれば、基地局装置1への電力配線工事が不要となるため、配線工事の作業量を削減でき、装置1~3を含む基地局システムの設置がいっそう容易になる。
実施の形態1及び2では、通信と電力供給のために通信ケーブル41及び42(e.g. STP(Shielded Twisted Pair)ケーブル)が共用される例について示した。しかしながら、通信と電力供給のために共用されるのは電源ケーブルであってもよい。つまり、無線伝送装置2への電力供給のためにデータ転送装置3と無線伝送装置2を接続する電源ケーブルが、データ転送装置3と無線伝送装置2の間の通信のために共用されてもよい。
