This new band can have enough channel bandwidth for high quality sound and hight quality of service. The encoding/decoding start to finish should employ open standards uncontrolled by special interests. The public is not going to have this Ibiquity crap shoved down their throat.. The currently employed digital radio old technology RF modulation scheme should not be used. It does not work well for vehicles in motion. The new band might also consider using several lower power transmitters instead one high powered transmitter for a station. This together with low audio compression rates will reduce receiver DSP workload helping to make portables a reality. Using stable open standards will remove the reluctance of semiconductor manufactures committing to making chips that operate on the new band. Another aspect of the new radios is that they should be software upgradable by the consumer like most computer appliances. Larger radios and units in car dashboards should have screens for traffic conditions, weather, album covers and the like. This new service could be a mix of free commercial sponsored and subscription services catering to what an individual wants. http://tech.yahoo.com/news/nm/20081010/tc_nm/us_fcc_airwaves_1 The VHF Low TV band would work OK. 54-72, 76-88 Megahertzes. *Too noisy for digital TV, may work OK for DAB.- Hide quoted text - - Show quoted text - |
