I assume that the TV is connected through the modem to the Internet just like everything else or does the ONT have to go behind the TV because it requires direct connection to the TV now or in some future technology that has yet to be seen in NZ?

I therefore presume that I can run CAT5 from the modem to the TV through the house. Even if the TV requires a direct connection to the ONT I suspect that CAT5 can be run from the TV to the ONT.

Have I got this right?

The plan is to put the ONT close to the server and run a CAT5 cable to a spot behind the TV and connect a multi-port switch so that the Panasonic DVR and TV can both connect to the Internet.

There is no technical reason why the ONT should be behind the TV. Mine's in the garage and no problems whatsoever.

The ONT can go anywhere - however in many homes the TV is the entertainment hub of the home and often central so makes a very obvious and logical location to install it.

UFB was designed and engineered so it could support RF over fibre but it's unlikely we'll ever see this in NZ.

I want to have my ONT situated in the rear of my lounge where I have my routers, telephone ATA and main computer, etc.

Hopefully the scoping tech will agree to the ONT location.

This is so I can run my important stuff off one UPS. If I put my ONT in my garage I would require a 2nd UPS.

My TV is at the other end of my lounge and hooked up by 5GHz WiFi.

I don't care if my TV stops on a power outage.

Cheers

Sadly so much was pinned in rfog that impacted on ufb installs, particularly in MDU's yet it's likely never to make the light of day.

Chrous are already doing trials https://company.chorus.co.nz/chorus-trial-live-4k-broadcasting-service-over-fibre . No idea if other LFCs are planning to do this.

Sorry that is not rfog, which is what much of the install constraints were set about, the above link refers to ip streaming based services, uni or multicast.

If I can get 4k or 8k over my fiber worth high definition audio I dont really care which protocol is used !

During the recent India Australia test cover on sky, fox was advertising 4k cricket coverage.

The other half was won over to 1080 ten years ago by the Tour de France coverage. Hoping for similar with 4k tour de France...

Agreed. The history is that it was expected that many tvs will have a set top box connected which require Ethernet connectivity but is unlikely to have wifi connectivity. So it needs cable between the ONT and STB.

If the ONT was installed in another part of the house then someone would have to pay to run the cable between the ONT and the RGW/STB. To avoid having the house owner pay for this cable, it was promoted that the ONT should be by the t.v. And therefore the cost of “getting to the t.v.” became part of the costs that were bourne by the LFC or Chorus and was part of the free install to home owners even if it was not the optimal solution for the LFC or Chorus.

As sbiddle says, the t.v. Is usually near the middle of the house so the wifi would reach the most used areas and most computers etc. would connect via wifi so didn’t need to plug into the ONT/RGW.

If you have a house that has cat 5 cabling in it, I would definitely put the ONT in the home distributor or wherever is the central point for the wiring and use Ethernet cabling to get to the tv/STB.

wifi uses CSMA for multi user access so a tv streaming will drastically slow down other devices with collision collapse.

This means its best to always hard wire a tv or settop box using ethernet cable.

If something is in a fixed location it should always be hardwired, not wireless.

The irony of this is it's one of the first things you'll learn and be told if you attend any good wireless training courses.

I plan to eventually hook up my TV with copper ethernet back to my router.

I would guess that collisions are most likely on 2.4GHz WiFi.

Exceptions may be:

- Multi channel 5GHz WiFi (maybe with slower speed to users)

- Dedicated multi channel 5Ghz WiFi to TV.

Not 2.4 on 5Ghz for sure

If you get any device transferring data on the same AP/SSID than the tv then there will be collisions, its how wifi serves multiple devices at the same time.

I dont think you can do multiple channels from the same AP, and I doubt many tvs will be supporting MU-MIMO AC wifi.
