A telecom ruminant is digesting the possibility that a 3Kb/sec duplex voice stream is not exactly a demanding broadband application.
That’s because bandwidth is not throughput. Throughput is what users value (by definition!). Throughput is “end user valued stuff”. Throughput of a “chatty” application depends as much on latency as peak transmission capacity. Which is why geostationary satellite is permanently shafted as a means of delivering top-tier connectivity, unless Einstein is planning a second coming. Useless for gaming, hopeless for voice. It’s why FLASH OFDM will constrict the market for CDMA technologies: time to obtain and release transmission channels is small.
