Broadband light years ahead?

[#1]

Many years ago I was shown a demo of using lighting to transmit data around homes & offices, hearing no more I assumed it didn't have commercial potential.

Now there's talk of using lighting to provide superfast broadband.

Not convinced by this to be honest, it appears to be quite directional and who wants to sit in their lounge with all the lights on just so they can get a signal. Not to mention the excessive screen glare caused by them. In a working environment yes, but even then it would mean the lights needed to be on even in the middle of summer which isn't very environmentally friendly.

Maybe it`s a "slow news day"... and the BBC wish to bring some "light" releif to the mundane stories of the day

Back to the present : I’m watching CityFibre laying Gigafast cables outside our house. So far only Vodafone are supplying the services but the pricing looks very good....

they discovered the fat bergs cut the cables amongst other hazards to them in the sewers 

indeed laying the wires should be a simple case of pulling them trough existing ducts regardless and the real problems to expanding the fibre network are generally political obfuscation attempting to prevent a single unified provider from deploying the network operations frame to everyone... in some regards I can understand this sicne you dont really want one company to have and advantage over all the others ignoring the importance of compatibility and interconnectivity boosts that would occur for everyone
