This article reviews the features and architecture of the DTT technology with wireless return channel called DVB-RCT2 versus 4G LTE cellular technology, and compares them in terms of bandwith, modulation schemes, speed used in downlink (DL) and uplink (UL), Guar Interval used, access methodology, carriers used, IP content transmission, forward error correction, among others, with the aim of verifying which of these two technologies could be the most appropriate to provide Internet connectivity in rural areas of Latin America.
