Re: How's the latency? The latency for G.fast in normal operating mode (what is being used for these trials) and no retransmissions due to impulse noise, is sub millisecond in each direction. However, when operating in discontinuous operation (likely for low power mode) that latency will be all over the place. We expect the latency and jitter requirements for carrying IEEE 1588 v2 over the top will be good enough for LTE-FDD and LTE-TDD, however for LTE-A we might need to use hardware assisted timing; using NTR support in G.fast.

Re: How's the latency? The biggest issue in latency can be in the modulation.  So, when you say low latency are we talking about milliseconds, microseconds?

Re: How's the latency? It is my understanding also that the latency required for virtual relaity applications can onmly be delivered over fiber or wireless connections in a bext-gen 5G world.

But over copper, even with G.fast? That will be a tough ask.

How's the latency? How's the latency on G.fast? Based on my research this week, latency rather than bandwidth is the key issue in the emerging category of VR applications.

Makes sense to kick the tyres For any telco that has street cabinets with vectoring tech, it makes sense to kick the tyres of G.fast.

To be engaged with 60 operators is a nice number -- what really counts is the number of those that get to the same stage as BT. And I do believe that number will grow rapidly as long as operators can accurately work out the business case vs FTTH/P and plan for the next 15 years...
