Vortex waves: possible applications for radio communications?
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.
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.
TV signals on ultra-wideband optical fibre networks
Optical fibres are now increasingly popular in telecommunications, due to their extremely high bandwidth, their very low attenuation, their complete immunity to electromagnetic interference and their reduced diameter and weight.
For these reasons, they are playing an increasing role in trasporting TV content, both for in-building TV signal distribution within the multi-service optical infrastructure, which is mandated in all new buildings (Italian Law 164, 2014) and for TV consumption via broadband networks, which will benefit from ongoing investments in FTTH (Fiber to The Home) architectures, where the fibre is terminated at each building. In Italy, network operators are launching massive optical fiber investment plans over the next five years, not only to cover the most densely populated areas (A and B) but also for less profitable areas (C and D).
Satellite transmissions beyond S2X
The DVB is currently starting a Commercial Study Mission casting DVB’s Vision for Satellite Broadcasting, looking at the near- and long term, and going beyond classic geostationary satellite constellations, anticipating a successful bringing into use of future low earth orbiting payloads.
Rai-CRIT will participate in these activities, according to its leaderschip role and active participation in the DVB technical module dedicated to satellite transmissions, aiming at evaluating opportunities, times and methods for new standardisation activities.
Application of the WiB concept to DVB-T2
WiB (Wideband Reuse-1 Broadcasting) is a new system concept for DTT where potentially all frequencies within the Ultra High Frequency (UHF) band are used on all transmitter sites (i.e. reuse-1).
