RADICELLI-GARCIA, Ciro Diego  e  CARDONA-MARCET, Narcis. Configurable parameters of physical and MAC layer of a new DTT standard wireless return channel to provide Internet connectivity in rural areas of Latin America.

This paper proposes the elaboration of a guide to configure the parameters of a physical and MAC layer of a new second-generation digital terrestrial television (TDT) with a wireless return channel called DVB-RCT2, particularly on the physical layer; (i) transmission modes, (ii) the burst structures (BS1, BS2, BS3), and (iii) the medium access schemes (MAS) for different FFT sizes; and as for the MAC layer (i) the access modes by considering an internet band of 6 MHz. To obtain the information, the conditions of the RCT2 channel have been emulated in a broadcasting laboratory, where the transport stream (TS) has been generated to get different values on the operation from both the physical layer and MAC which are represented in different charts that demonstrate the DVB-RCT2 capacity over its predecessor DVB-RCT which makes this proposal an interesting alternative to provide internet access to rural areas.
