Not necessarily, but if the improvements that lead to 12Gbps includes refinement over signal processing, such that certain previously-garbled signal are being successfully decoded now, this will allow for better real-life speeds and latency. Obviously, this will not equate to 12Gbps but serving a thousand people with guaranteed speeds of 12Mbps and practically receiving (assuming not everyone is downloading) 100Mbps with minimal latency and packet loss would be great improvements. This is also the thing with Wi-Fi, you would unlikely to get ~6Gbps unless you're the sole user, but the improvements allow for faster and lower-latency real-life speeds.
