Version 6.04 (002)


LTE Advanced is a mobile communication standard and a major enhancement of the Long Term Evolution (LTE) standard. It was formally submitted as a candidate 4G system to ITU-T in late 2009 as meeting the requirements of the IMT-Advanced standard, and was standardized by the 3rd Generation Partnership Project (3GPP) in March 2011 as 3GPP Release 10.

The DVB-T2/LTE-A+ trial

Tower Overlay over LTE-Advanced+

Rai CRIT, in cooperation with RaiWay, launched in 2015 an experimental trial in Aosta Valley where two data streams share the same UHF channel in time-division: one conveys conventional HDTV programs targeting domestic DVB-T2 receiver, and a second one conveys a flow intended for 4G LTE-A+ devices such as smart-phones and tablets.

This brief note describes the context in which we operated, introduces the concept of Tower Overlay over LTE-A + (TOoL +) and shows the results of the trial carried out in the Aosta Valley.

Experimentation of the coexistence of Radio Link services and LTE in the 3.6-3.7 GHz band

The growing demand for transmission capacity for mobile access has led in recent years public administrations to consider new ways of spectrum management, which include sharing between different services and operators. At the invitation of the Italian Ministry of Economic Development we have participated and contributed to a field experiment aimed at assessing the problems of interference eventually suffered by Fixed Services (Radio Links for TV contribution / distribution) by LTE services in the 3.6-3.7 GHz band.
