多信道多点分发服务(英語:Multichannel Multipoint Distribution Service,缩写MMDS),旧称宽带无线电服务(Broadband Radio Service,缩写BRS),也称无线电缆(Wireless Cable),是一个无线电信技术,用于通用目的的寬頻网络,或作为有线电视节目接收的替代方案。
BRS频带使用2.5GHz至2.7GHz的微波频率。以BRS接收电视和数据信号是通过屋顶的微波天线完成。该天线连接到下变频器或收发器以接收和发送微波信号和转换它们到频率兼容的标准TV调谐器(英语:TV tuner)(非常类似卫星天线,其中的信号被转换为与标准电视同轴电缆更兼容的频率),部分天线使用集成的下变频器(英语:Digital down converter)或收发器。然后可以使用标准的电缆机顶盒或电视集成的数字调谐器解码数字电视频道。互联网数据可以用连接到同一天线和收发器的标准的DOCSIS电缆调制解调器接收。
在爱尔兰,自1990年起[6],UPC Ireland(英语:UPC Ireland)(以前为Chorus(英语:Chorus Communications)和NTL Ireland(英语:NTL Ireland))为几乎全国提供MMDS TV服务。最初分配的频带是2500–2690 MHz(属于“2.6GHz频带”),包括22–23的8 MHz模拟信道,数字电视被限制为2524–2668 MHz,由18个8 MHz数字信道组成。共使用两个数字电视标准:DVB-T/MPEG-2 in the old Chorus franchise area and DVB-C/MPEG-2 in the old NTL franchise area. The existing licences were to expire 18 April 2014 but Comreg, the Irish communications regulator, extended the licences for a further 2 years to 18 April 2016 at which date they expired together with all associated spectrum rights of use. The 2.6 GHz band spectrum will be auctioned off so that when the existing MMDS licences expire new rights of use can issue on a service and technology neutral basis (by means of new licences). As a result, holders of the new rights of use may choose to provide any service capable of being delivered using 2.6 GHz spectrum. For instance, they could distribute television programming content, subject to complying with the relevant technical conditions and with any necessary broadcasting content authorisations, or they could adopt some other use.[7]
在冰岛,自2006年11月以来,Vodafone Iceland(英语:Vodafone Iceland)运行Digital Ísland (Digital Iceland) - 用于365 (media corporation)(英语:365 (media corporation))的广播系统(以前由365 Broadcast Media运营)。Digital Ísland提供使用DVB-T技术及几个模拟信道的数字MMDS电视服务。MMDS频率范围 extends from 2500–2684 MHz for a total of 23 8 MHz channels, of which 21 are considered usable for broadcasting in Iceland. 模拟MMDS广播始于1993年,在2004年转向数字。
