Description
配線式通信は少なくとも2本の別個の導電体の使用を要する。該配線は、イーサーネットIEEE802ネットワーク(Ethernet(登録商標) IEEE802 networks)で使用される、カテゴリー5の種類の様な構造化された配線の設置の様に、該家庭内データ通信用に設置され、専用化された新配線である。しかしながら、家庭内での新配線構造体の設置は労働集約的で、複雑で、高価である。代わりに、特定の目的用に前に設置された現在の家庭配線は元のサービスが実質的に影響され又は劣化させられず、データ通信用に使用出来る。現在の配線は電話配線(telephone wiring)、電力ライン配線(power line wiring)そしてケーブルテーブイ配線(cable TV wiring)を含む。これらは下記の様に再検討される。
家庭内の電話サービスは通常2本又は4本の線(wires)を使い、電話セットが接続される電話出口を経由してアクセスされる。
該家庭内で、普通50又は60Hzの周波数である電力の配電用に使用される配線上でデータを伝送することが可能である。該電力へのアクセスは該家庭中に分布する電力出口(power outlet)を経由して利用可能である。この様な配線は2線(相用及び中性点用)又は3線(相用、中性点用、及び接地用)から成る。
家庭内でテレビジョン信号の配布用に使用される配線上でデータを伝送することも可能である。この様な配線は通常同軸ケーブル(coaxial cable)である。
家庭内のデータネットワーク化用の無配線式解決は導電媒体無しで伝播する波動を使う。普通3つの主な技術が使用される。
米国特許第4,509,211号及び欧州特許EP第0798923号は共に該赤外線リンクの動作範囲を拡張するために電話(又は他の)配線(wireline)ネットワークを経由し赤外線制御ユニットを使用してテーブイ(TV)セット又はブイシーアール(VCR)の遠隔制御を可能にする同じニーヅに取り組んでいる。すなわち、両室内の適当なトランシーバーの使用により異なる室内のテーブイ又はブイシーアールを制御するように該赤外線リンクの範囲が拡張され得る。換言すれば、これらの両参考文献では原理的考慮は該制御ユニットであり、該配線ネットワークは単に該制御ユニットへの付属物(adjunct)又は延長(extension)である。
本発明は、無線式ユニット(wireless unit)への付属物でなく、寧ろ、そこでは無線式ユニットは該ネットワークが有線と無線の両データ通信(wireline and wireless data communication)を可能にするよう拡張されるような該ネットワークの必要不可欠部品である、様な完全集積化データネットワークを提供するニーヅに関する。この様な集積化ネットワークでは有線か又は無線か何れかの接続を使用して該ネットワークを通して同じデータが搬送されることが出来なければならない。これは、両方の場合、無線で運ばれるよう受け入れられるデータのみが該アイアール(IR)又はアールエフ(RF)制御データである、米国特許第4、509、211号及び欧州特許EP第0798923号での場合でない。該アイアール又はアールエフ制御データは該ネットワークの配線式ポート内へ直接運ばれ得ず、実際、そうする何等のモチベーションも無いが、それはそれが本来無線式であるからである。しかし、例えモチベーションの欠如を離れても、該アイアール又はアールエフ制御データは普通該ネットワークを通して運ばれるそれとは異なる種類のデータである。
米国特許第4、509、211号も欧州特許EP第0798923号も共に、該ネットワークの1点で無線で運ばれたデータは該ネットワークのもう1つの点で配線接続を介して受信され得るように、同じデータが(必要があればプロトコル変換後)該ネットワークを通して運ばれることを可能にしない。寧ろ、テーブイセット又はブイシーアールの遠隔制御用に意図されたアイアール又はアールエフ制御データは共に該ネットワーク内に供給されそしてアーアール又はアールエフ信号として該ネットワークから外へ供給されねばならず、それはさもないと該制御データは該遠隔のテーブイセット又はブイシーアールを制御出来ないからである。
かくして、この様なデータユニットが家庭又は他の建物内でネットワーク化出来て、一方可動性と使用の容易さを提供する様な、データユニット間の家庭内でのデータネットワーク化を実施する手段の、広く認識されたニーヅがあり、それを持つことは非常に有利である。
特に、互換性を有するよう配線によるか又は無線でか何れかで同一データの伝播をサポートするネットワークを提供することは望ましい。更に、この様なネットワークと共に使用するためのトランシーバーは追加的部品の外部接続の必要無しに該トランシーバーを経由して直接該ネットワークへ配線式か無線か何れかの接続を可能にすべきである。
該少なくとも1つの配線式セグメントは、該建物内の少なくとも1本の導電ラインを備えており、前記導電ラインは少なくとも2本の導体を有しデータ通信信号を伝送するよう動作しており、
該少なくとも1つの無線式セグメントは無配線式媒体(non−wired media)上でデータを通信するよう動作しているが、
該アダプターモジュールが
配線式セグメントへの配線式接続用の配線式トランシーバーと、
無線式セグメントへの無線式結合用無線式トランシーバーと、そして
互換性を有するよう配線によるか又は無線でか何れかで同一データの伝播を可能にするよう該配線式と無線式のセグメント間でデータを適合(conforming)させるために配線式トランシーバーと該無線式トランシーバーとの間に配置されたプロトコルアダプターとを有していることを特徴とする。
本発明のもう1つの側面に依れば、この様なローカルエリアネットワーク内で少なくとも1つの配線式セグメントと少なくとも1つの無配線式セグメントの間をブリッジするためのアダプターモジュールが提供される。該アダプターモジュールは、
少なくとも1つの無配線媒体上でデータ通信信号を伝送するために動作する少なくとも1つの無線式トランシーバーを具備しているが、該アダプターモジュールが、
建物内の少なくとも1本の導電ライン上でデータ通信信号を伝送するために動作する少なくとも1つの配線式トランシーバーとを具備しており、前記導電ラインは少なくとも2本の導体を有しており、そして該アダプターモジュールが又
互換性を有するよう配線によるか又は無線でか何れかで同一データの伝播を可能にするよう該配線式と無線式のセグメント間でデータを適合させるために該配線式トランシーバーと該無線式トランシーバーとの間に配置されたプロトコルアダプターを具備することを特徴とする。
この様なアダプターモジュールは出口内に全部が又は部分的に集積化されてもよい。
本発明のなお更に進んだ側面に依れば、データ通信信号を伝送するローカルエリアネットワークであり、該ローカルエリアネットワークが配線式セグメントと無線式セグメントとを有する、該ローカルエリアネットワークをサポートするよう建物内の現在の配線をアップグレードするための方法が提供されるが、該方法は、
配線式トランシーバーを経由して出口を該配線式セグメントに接続する過程と、そして
該配線式トランシーバーと無線式トランシーバーとの間に接続された出口内のアダプターモジュールを経由して該配線式セグメントと該無線式セグメントとの間をブリッジする過程とを具備しているが、該方法が
該出口内に必要不可欠部品として該配線式トランシーバーを提供する過程と、そして
互換性を有するよう配線によるか又は無線でか何れかで同一データの伝播を可能にするよう該配線式と無線式のセグメント間で、該アダプターモジュール内で、データを適合させる過程とを具備することを特徴とする。
1.他の形式の電磁的伝送により達成される無配線式通信。電磁的スペクトラムの種々の部分の電磁波が通信用に使用出来る。例えば、低周波電磁放射は搬送波(carrier)無しに短い距離に亘りオーデイオ周波数信号を伝送するた使用出来る。無線周波伝送はこの一般的電磁的伝送の特殊ケースである。前に注意した様に、光も又電磁的放射の特殊ケースであるが、光の特性は該電磁的スペクトラムの他の使用可能な部分での電磁的伝送のそれらと特異に異なるので、ここでは別に取り扱われる。
の様な、他の種類の無配線通信にも等しく適用できる。
本発明も又上記説明のネットワークをサポートするために現在の導電ラインをアプグレードするためのキットを考慮している。図8は出口132と出口134と設置取扱説明書136を含むこの様なキットの実施例を図解している。出口132は配線式セグメントへ接続するための接続部144と、建物壁内に設置するためのフランジ146の様な設置点(mounting points)とを有する。又出口132はケーブル経由で外部デバイスへ接続するためのジャック138とジャック140、そして無配線式セグメント経由で外部データユニットへ接続するための変換器142を有する。出口132内には、前に説明され、図5で図解された、本発明のモジュールがある。1実施例では、変換器142は無線周波トランシーバーである。もう1つの実施例では、変換器142は組み合わされた発光ダイオードとフオトセル(photocell)受信器である。なおもう1つの実施例では、変換器142は組み合わされたスピーカーとマイクロフオンである。同様に、1実施例では、ジャック138は電話ジャックである。もう1つの実施例では、ジャック138は電力ソケットである。なおもう1つの実施例では、ジャック138はケーブルテレビジョンジャックである。1実施例では、ジャック140はデータジャック(data jack)である。図8に図解される該キットの実施例は2つの出口、出口132と出口134を有し、それらは実質的に同一に図解されている。しかしながら、もう1つの実施例では、該キットは出口132だけを有する。なおもう1つの実施例では、出口134は変換器を含まない。又異なる実施例では、他の変型品もあり得る。
