Glass-to-glass latencies are extremely dependent on what cameras and displays are used.
Common 4G link latencies are 15-30 ms. With fast cameras and displays we can get sub-50-ms glass-to-glass over 4G.
For sure something like this should easily get lower than 110 ms, if care is taken to use fast cameras and displays.
- bronco21016 5y agoWiFi links can easily achieve similar latency. The cameras, displays, and interfaces used are certainly a factor in the overall glass to glass latency. There are also issues of codecs and hardware accelerated decoding/encoding of video. Where “just use 4G” misses the point though is that this system is connectionless and the FEC that comes with that introduces some latency as well. This could probably be optimized somewhat as well. The trade off with this type of system though is that you don’t 100% lose video for a considerable amount of time if the link is broken. When a two-way radio link is broken there is considerable latency waiting for the connection to be reestablished.
