Return Channel
Brazilian broadcasters defend the use of the current analog TV VHF band for the "return channel", the channel that allows digital TV sets to send data to broadcasters as part of an interactive TV service. That 700 MHz band enables the return channel using WiMAX technology, which would be another option to be added to the regular ones (ADSL Internet, Cable Internet, GSM EDGE, GSM 3G, WiFi or dial).
That idea was to be presented to the Brazilian Government in the WiMAX Forum in June 2009, in the hope of creating an international standard for the return channel.
