Cable networks for television signals, sound Signals and interactive services - Part 2-3: LTE (4G) Interference Mitigation Filters

This Technical Specification provides requirements to passive filters intended to reduce RF interference from LTE Base Stations (LTE-BS) and LTE User Equipment (LTE-UE) to receiving equipment and cable distribution systems of broadcast DVB-T and DVB-T2 signals in the VHF and UHF bands. While primarily intended to be used with VHF/UHF DVB-T and DVB-T2 receivers and signal distribution systems, filters can also be useful for mitigation of interference to VHF FM or DAB radio.

Kabelska omrežja za televizijske signale, zvokovne signale in interaktivne storitve - 2-3. del: Filter LTE (4G) za preprečevanje motenj

Ta tehnična specifikacija določa zahteve za pasivne filtre za zmanjšanje RF-motenj pri sprejemni opremi in kabelskih razdelilnih sistemih za radiodifuzijo signalov DVB-T in DVB-T2 v pasovih VHF in UHF, ki jih povzročajo bazne postaje LTE (LTE-BS) in uporabniška oprema LTE (LTE-UE). Medtem ko se filtri uporabljajo predvsem s sprejemniki VHF/UHF DVB-T in DVB-T2 ter sistemi za razdelitev signalov, so lahko uporabni tudi za preprečevanju motenj pri radijskih signalih VHF FM ali DAB.

Introduction
Standards and deliverables of EN 60728 series and EN 50083 series deal with cable networks including
equipment and associated methods of measurement for headend reception, processing and distribution of
television and sound signals and for processing, interfacing and transmitting all kinds of data signals for
interactive services using all applicable transmission media. These signals are typically transmitted in
networks by frequency-multiplexing techniques.
This includes for instance:
a) regional and local broadband cable networks;
b) extended satellite and terrestrial television distribution systems;
c) individual satellite and terrestrial television receiving systems;
and all kinds of equipment, systems and installations used in such cable networks, distribution and receiving
systems.
The extent of this standardization work is from the antennas and/or special signal source inputs to the
headend or other interface points to the network up to the terminal input of the customer premises
equipment.
The standardization work will consider coexistence with users of the RF spectrum in wired and wireless
transmission systems.
The standardization of any user terminals (i.e. tuners, receivers, decoders, multimedia terminals etc.) as well
as of any coaxial, balanced and optical cables and accessories thereof is excluded.

4.1 General
To comply with this specification a filter shall pass a range of frequencies (the pass-band) which includes a
number of VHF and UHF TV channels and shall attenuate a range of LTE frequencies (the stop-band). In all
cases the stop-band lies above the pass-band.
