It is applicable to cable networks intended for television signals, sound signals and interactive services operating between about 5 MHz and 3 000 MHz. The frequency range is extended to 6 000 MHz for home distribution techniques that replace wired cords with a wireless two way communication inside a room (or a small number of adjacent rooms) that uses the 5 GHz to 6 GHz frequency band. This second edition cancels and replaces the first edition published in 2009, and constitutes a technical revision. It includes the following technical: update of performance requirements in Clause 7 to include those for DVB-T2 signals. This publication is to be read in conjunction with IEC 60728-1:2007.
