ま え が き一般社団法人電波産業会は、無線機器製造者、電気通信事業者及び利用者等の参加を得て、各種の電波利用システムに関する無線設備の標準的な仕様等の基本的な技術条件を「標準規格」として策定している。
標準規格は、周波数の有効利用及び他の利用者との混信の回避を図る目的から定められる国の技術基準と、併せて無線設備の適正品質、互換性の確保等、無線機器製造者、電気通信事業者及び利
用者等の利便を図る目的から策定される民間の任意基準をとりまとめて策定される民間の規格である。
本標準規格は、「800MHz 帯デジタル MCA システムの無線区間インタフェース」について策定されたもので、策定段階における公正性及び透明性を確保するため、内外無差別に広く無線機器製造
者、電気通信事業者及び利用者等の利害関係者の参加を得た当会の規格会議の総意により策定されたものである。
本標準規格で規定されている範囲は、通信を行うために必要な最小限の規格を定めたものであるが、本標準規格の実際の利用にあたっては、800MHz 帯デジタル MCA システムを構築する者が、本標準規格を逸脱することなく独自に定めることが可能な規定及び規格値等を併せて利用することが必要である。
本標準規格が、無線機器製造者、電気通信事業者及び利用者等に積極的に活用されることを希望する。
