The activation in the UHF band of 4G/5G Base Stations can have in some areas an impact on TV reception, especially in case of community antenna installations. The adoption of proper interference mitigation techniques, such as the insertion of specifically designed filters at the head-end of the distribution network, allows to mimimise the effects in most situations.

The presence of 800 MHz LTE signals within the UHF band traditionally used to distribute television signals may in some cases cause interference problems.

The so-called “White Spaces” of the television band (TV White Spaces) represent free spectrum portions (locally and / or temporarily unused by users assigned to those frequencies) that can be used by secondary applications requiring reduced power, provided they do not generate interference with primary users.

In recent years, the research community have shown interest in the study of some “non-conventional” properties of electromagnetic radiation in order to evaluate its possible application in the field of applied sciences.

3GPP has defined in Release 14 the new eMBMS system, whose characteristics are well aligned to the technical requirements coming from the broadcast sector for TV services.
