Mitigation techniques of the interference generated in TV distribution installations by 4G/5G signals in the 700 and 800 MHz bands
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.
Assessment of the interference generated by the LTE signal on the head-end amplifiers of the TV reception systems
The presence of 800 MHz LTE signals within the UHF band traditionally used to distribute television signals may in some cases cause interference problems.
Analysis of the interference generated by TV White Spaces on TV reception systems
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.
Long term perspectives of DTT Convergence towards 5G: Applications of 3GPP Rel-14 to Italian scenarios
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.
The TV programme list is enriched with new channels received via the Internet
The future DVB-I standard aims to deliver TV programmes over the Internet, so that they can be received and displayed by a variety of connected receivers (TVs, PCs, tablets, smartphones) with the same ease of use as today’s traditional TV programmes received from an antenna.
The new DVB-I services will be discovered by means of an installation procedure functionally equivalent to a frequency scan, and included in a channel list having a Logical Channel Numbering (LCN) harmonised with broadcast services.
