additionally to the Expense, in some situations (for example in a burning house) where the radio reception gets bad an analog radio degrades better: the signal gets noisy but you can propably still understand what's said, and you can ask for repeats and piece together something out of a few retransmissions.
With digital radio on the other hand, a bad signal results in lost chunks. There the transmission is clear until it gets choppy and that's a lot harder to make anything out of.
- heavenlyblue 7y agoBTW, does anyone know why aren't there codecs that would increase the speaking latency but spread out the information over a wider range of the signal, so that the lost chunks could simply be reconstructed from last and the next chunks received?
- Grollicus 7y agoThat's just another ECC and things like raptor codes to exist, which could achieve analog-ish characteristics in digital transmissions. I suspect this kind of encoding works badly with encryption, as decryption needs a perfect preimage otherwise the decrypted message will simply be garbage. Also, even a slightly increased delay makes for very awkward conversations.
