Ok All Irish ISPs get stuck into this now!

Seeing as we dont and probably wont see FTTC or FTTH for decades
And LTE/Wimax etc are not the best solution how does this sound for our lovely little island to replaces our shabby copper strings? hmmm?

I didnt get a chance to view the vid but had a quick look at the text sounds promising! cant wait lol

Read about this a while back. Sounds pretty far fetched tbh. You'd need direct line of sight and it'd be fairly short range.

Not suitable in a wet country like Ireland!!

+1 on what Sponge_Bob said.

We'll have FTTC long before "Li-Fi".

I know Dorset college has it on 3 of its buildings in Dublin. When it rains or is foggy the throughput drops rapidly.

If only...........:)

Sounds absolutely fantastic and if implemented could revolutionise how we use the Internet.

FSO (free space optics) is not going to revolutionise broadband. Sort of good for point-to-point in dry climates. Worse than fixed wifi in most cases.

Why is LTE not the best solution?

This uses OFDM - as does LTE or 802.11n 74Mbit wifi

LTE willl be available worldwide in the nest 2-3 years. Will this?

No details on its range, applicablity, power usage, TTM IOT etc.

LTE is just 3G but better, less breathing all native IP. It's not economically feasible to deliver Broadband with it (too many base stations). Fibre would be cheaper and 100 faster.

Latest point to point fibre gear can deliver 100x 100gbit wavelengths per fibre ....that is 10 Terabits per fibre 10,000,000 Megabits.

Latest fibre PON standards can deliver 10gbit shared by perhaps 30 premises ( a measly 300mbit each) but over a run 30km long.

We should be looking at PON for residential areas, rural and urban and point to point fibre in denser areas and business zones. HFC cables , as deployed by UPC, is like a PON that uses copper some of the time. Eventually UPC will push fibre INTO the home not within 150-500m of it as they do now.

Wireless ( in an advanced economy...not Ireland) is really only for when you get caught short over a coffee or in the car ....except that in Ireland we are forced to rely on technology designed for those who are temporarily off fibre as you do on occasion. Wireless spectrum is scarce and they are not making any more of it. It is also useful 'in building'.

The less wireless snakeoil around here the better. You are only talking next years midband in most cases.

A poster on another forum is taking part in the BT trials in Southern England and gave this as his present connection speedtest ....

I think this link refers to the same trial ....

http://www.guardian.co.uk/technology/2011/may/25/bt-trial-4g-broadband-in-uk

A key element of the test is that it will be using the 800MHz frequency band, which should have substantially longer range than the higher frequencies on which mobile masts currently transmit. That in turn should improve reception over distance, meaning that mobile carriers will not have to extend their existing networks to create blanket 4G coverage when the radio spectrum is auctioned off by Ofcom next year.

It sure looks enticing to those of use on low speeds ...... :cool:

Looks like LTE affects digital tv,
