AT&T was broken up in 1982. Call quality is quite a bit better since then.
In the country, we had a party line up to that point. Same location today is still rural but has digital telephony, high speed Internet, and multiple cellular providers.
- kick 7y agoBasically everyone agrees that both latency and audio quality has decreased, and that can be measured (without sophistication) simply by checking radio & television call-ins over the past fifty years. It was slightly reduced with the introduction of wideband audio (not the latency problem, though), but has mostly gotten worse over time. This is a great answer on Quora from a few years back to a question on why call audio hadn't improved, where the author explains that it hadn't just not improved, it had actually declined over time: https://www.quora.com/Why-has-the-audio-quality-of-phone-calls-not-improved-over-time-like-visual-media-has/answer/Dave-Haynie https://www.quora.com/Why-has-the-audio-quality-of-phone-cal... There was also a great IEEE Spectrum post from a bit before the takeover of VoLTE and wideband audio as to why the decline had happened (and was probably going to accelerate as providers moved to switch from the PSTN to VoIP internally): https://spectrum.ieee.org/telecom/wireless/why-mobile-voice-quality-still-stinksand-how-to-fix-it https://spectrum.ieee.org/telecom/wireless/why-mobile-voice-...
