The company has commercialized some of these innovations to create xMax®, a private fixed and mobile wireless broadband system that delivers voice, video and data services for residential, business and government users. xMax currently operates in the unlicensed 900 MHz ISM band, although it has been designed to be programmed for operation in any licensed or unlicensed frequency from approximately 300 MHz to 3 GHz.〔(【引用サイトリンク】title=Response to Notice of Inquiry Before the Federal Communications Commission )〕 The xMax system is designed to allow mobile operators to utilize free, unlicensed 902-928 MHz spectrum, which is available in most of the Americas. Unlicensed spectrum is an affordable alternative to licensed spectrum – such as what broadcasters use to transmit their signals. Any company or consumer can use unlicensed spectrum simply by following well-known rules. ==See also== * cognitive radio * software defined radio * dynamic spectrum access * radio frequency * radio spectrum * mobile VoIP 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「XG Technology」の詳細全文を読む スポンサード リンク
