FTTP installation

[charles]

my former neighbour put it quite well: "I have 3 teenage children"

Another issue is online games. It takes longer to transfer a given packet over a slower speed link. Gamers like snappy responses to their input in order not to die online ;-)

One of my neighbours only has internet on her mobile phone.

Her husband and her have 5 children.

games ?.

They are the people who should have to pay a big premium.

ZZZZzzzzzzzzzzzzzzzzzzzz

So She doesn't care much for the planet then ?

[charles]

The chairman (female) of a society I'm involved with has just (two days ago) had child no 5, in just over 5 years, The message of facebook is "family now complete". SWMBO's comment: just wait until she has 5 teenagers!

[Scott]

Could be the same issue :-)

[Andrew]

And .... they are bunking off school to attend protest rallies complaining about deforestation, global warming, slow internet, expensive car insurance, 'lost' (uncool) smart phones, ...

one obvious use case is Cloud storage

Previously one would use a NAS on their homer network.

Now you can buy storage from MS OneDrive or from Googledrive or from Amazon EC2

so a fast fibre connection means that the cloud storage is juts as fast if not faster than a home NAS plus you can access your stuff from anywhere in the world.

Another use case is VPN'ing back to home from a mobile phone over 4g and soon 5g instead of using a public wifi network. Fibre tends to be symmetric whereas for ADSL/VDSL/Cable the DL speed is higher that teh UL speed.

Another use case is several members of the family all streaming UHD content simultaneously......

Well I don't think Openreach allow any Tom, Dick or Harry access to their ducts/chambers etc but I guess you could DIY or contract out any works that didn't involve access to OPenreach's infrastructure, say the trench from the nearest chamber to your property so all they have to do is drop their duct into it.

[jrwalliker]

The kind of fibre service that BT are offering is unfortunately not at all symmetric. The uplink is time division multiplexed in the same sort of way that cable services operate.

I dont think so.

No on uses TDM these days - its all packet switched

[Andy Burns]

He's right ...

Everyone is sharing a single fibre at the exchange-end, one downstream wavelength gives 2.48 Mbps, a different wavelength gives 1.24 Mbps upstream, closer to the premises it gets passively optically split for up to 32 sub-fibres to the premises.

All downstream packets arrive at all premises and the ONT filters out everyone's but yours, there are timeslots that you get to transmit on the upstream wavelength to fit your traffic around everyone else's.

Packet switched over 21CN once it gets back to the exchange.

G.984 if you're bored ...

[Andy Burns]

Oops, Gbps.

[Dave Liquorice]

downstream

Or even up to 64 but that starts to limit the range to less than 10 km on a subs fibre. B-)

else's.

Wavelength for the up/down combined streams. Time for individual connections within those streams.

Are we also being sold a pup again with "1 Gbps capable" connections? If the down stream is limited to 2.48 G bps and all 32 customers are trying to fill their pipe surely all they'll get is 2.48/32 ~ 78 Mbps throughput even if individual packets are signalled at 2.48 Gbps.

well the fibre rollout (FTTP) that is happening in my road has a top tier package which is 900 MB/s *both* ways.....

I currently have VM cable which is 200 MBit/s down and 20 MB/s up...

Needless to say, I will be switching as its also cheaper than VM!

[Robin]

ISTM BT are no different from VM in promising (maximum) /speed/ rather than absence of /contention/ - though ISTR BT were looking to upgrade the down from 2.5 to 10 using newer kit on newer installations.

Still a matter of business products if you want freedom from contention?

[The Natural Philosopher]

Contention is meaningless except in a packet switched context. If it IS time division or frequency division multiplexed, there *is* no contention. The guaranteed subscriber time/frequency slots exist whether full of data, or empty.

No matter which technology is used, the 'last mile' is not contended.. It's the backhaul that is.

[Mathew Newton]

We've got a 60 Mbps FTTC connection and according to the router we downloaded 621 GB last month! Whilst we stream all our TV, and download quite a few films (and F1 races), I must admit I didn't think it was going to be that high.

[John Rumm]

Well according to my stats:

"During the time period 1st August 2020 to 12th August 2020 your bandwidth use was:

238.25 GB Download 8.2 GB Upload

The figures above cover 11 days."

The quantity of data will be influenced by the speed though.

Slightly different issue. Much depends on what you do... Here it would be quite common to have three video streams running at once, and since the link is capable that would aauto adjust to three high def streams.

If you are a content producer, then having "only" 30Mbps upload speed could actually be quite limiting. Same can apply for things like online backup or cloud storage.
