[TG] [TG11] Miracast with the Axiom Pro

[Tom - Raymarine - Moderator]

Hi George,

I asked on our global internal tech-support message system for other people's experiences on Miracast and dongles and the response I got was that people weren't reporting problems with the MS device. We don't have any recommendations for alternatives, in theory anything properly (Miracast) certified should be good.

Thanks, those screenshots are interesting.

In 101815, the signal level is very strong, and it might be that the brief dip wasn't long enough to cause a buffer under-run on the wireless display streaming, or perhaps the wireless display direct connection didn't experience such a dip (we can't tell from the information available through a phone app like this what the cause of the dip in signal level was.) I would expect there to be a bit of buffering on the Miracast signal so that brief interruptions or drops in bandwidth could be tolerated.

Re. 104733, the signal level in the latter part of the graph looks pretty low to me. Based on my own informal trials here, I think we need around -60dBm for a solid Miracast signal.

Re. 101305, I would certainly expect that a drop in Miracast Wifi signal level this long would cause loss of picture at the TV (if the video buffer were enough to cover outages this long, the picture lag would be intolerable), and the fact that the video picture was lost at the same time as you saw the loss of signal on the phone suggests to me that the cause is either:

• Something external - noise - that affects both Wifi links together (MFD-dongle and MFD-phone)
• Something at the MFD, such as an internal issue or dip in power supply, that brings down all Wifi simultaneously
  

What I would be focussing on is looking for a pattern in the Wifi signal losses on the phone app, to see whether they relate to something else going on on the boat.

Regards,
Tom
