Overview
IEC 60728-1-1:2014 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies requirements for RF cabling in two-way home networks. This standard applies to networks distributing television signals, sound signals, and interactive services within the home environment. It covers wired and wireless transmission paths operating primarily between 5 MHz and 3,000 MHz, with extensions up to 6,000 MHz for wireless communication replacing wired cords.
The 2014 edition is a technical revision of the 2010 version, incorporating updated performance requirements to support modern digital broadcast technologies, including DVB-T2 signals. This standard should be used alongside IEC 60728-1:2007 for comprehensive understanding and implementation.
