5. Examples of OFDM applications

OFDM is used in most wireless transmissions: WiFi wireless local area networks (or more precisely IEEE 802.11a and IEEE 802.11g), LTE and WiMax cellular networks, digital terrestrial television (DVB-T, DVB-T2), but also for ADSL wire transmission. In the field of cellular radio networks, while there was considerable debate in the 1990s about the respective advantages of TDMA (used for GSM) and CDMA (used for the American IS-95 system and then for UMTS), OFDM is now considered the best transmission technique, and the subject is no longer debated.

In the table 1 , we present some possible settings for WiFi, WiMAX, LTE and DVB-T2 systems. WiFi wireless networks (IEEE 802.11g standard) were one of the first systems...
