Any News on Powerline Broadband?

Paladin

I know its been talked about a lot but has anything significant happened since this: http://www.theregister.co.uk/2003/08/19/ireland_to_trial_broadband_over/

Im assuming you mean Brendan Kehoe from Irishwan? Wasn't him that wrote it. I work in telecoms research and I dont remember if it was an open invite or not to be honest but I can check. Didnt post his name because I havent asked him if he wants me to or not. Waht I will say is he is more then qualified to comment.

I notice you havent given any opnion?

BigEejit

My opinion is that the sooner its rolled out the better and hope the lawmakers dont get taken in by the alarmist propaganda being peddled by "the enthusiasts"

[edit] apologies to bkehoe for mistaking the propaganda above as being his [/edit]

Rew

LOL id be intrested to the author versus you as a head to head.

Im curious what makes you qualified to call it "alarmist propaganda being peddled by the enthusiasts"?? (Obviously I havent given his qualifactions but lets assume they are very good)

bkehoe

I most certainly didnt write that. BPL will be great when/if they get the technology to work properly. The technology which causes massive interference on the HF bands is unacceptable, and shouldnt be let out into the open market. That report on bpl was one of the best I've seen in one piece, and is very clear of the destructive effects BPL has. There are various primary users of the hf bands - something like bpl is not permitted to interfere with primary users. Some day I hope to make use of the HF bands, and I just hope that the powers that be see sense and there's still a usable band there by that time.

There would be a head to head alright ... commonly referred to as a nutting .... :P

You want to know why I look forward to it? its an alternative to the other copper pair coming into everyones house. Dont give me the guff about wireless all over the country, we all know that that will never happen in the extremities and there will be wireless dead spots anywhere there are hills or obstacles. The other reason is that any time I see a special interest group screeching and roaring about the bad things that could happen because of something that is to their detriment when it is for the greater good I'd like to stick my oar in for the silent majority...

iwb

Opinions are like arses, everyone has one. Here's mine.
As a technology, it has been coming for years and still isn't here. I can't profess to know much about it at all except what I have read.
While there may be a way for it to coexist with existing radio frequency users, there are other considerations.
First of all, it doesn't cross transformers, so in Ireland, how many premises will it serve per transformer? I think it is going to be a significant extra cost for it to cross the transformer.
Second, you are working now with HT on the primary side which absolutely means ESB involvement. (probably means that anyway, at any voltage). That means buy in form them. I haven't seen any indication that they are willing to do it. In fact, both ESB and Bord Gais have shown hesitation in getting into retailing broadband at all.
Finally, on the technology side, I think the maximum bandwidth currently available is less than 30Mbps. Yeah, sure that might be great for rural areas but does it have a maximum range? How costly is it to repeat it and cross more transformers? What about maintenance?
Overall, it will probably never become very popular. Why did Nortel quit the market a while back? I read about it in 1998 as the next big thing while working at Nortel. They really hyped it up internally.

So are water pipes. Let's campaign for broadband over water lines. What's that you say? It won't work? Bloody naysayers.

BPL isn't a rural solution. It won't work in Ireland. This has been discussed to death. Move on.

The coverage map for the last tranche of wireless licenses does not cover the extremities .... for instance a rural town like Caherciveen in Co. Kerry is not covered by it iirc and with just less than the trigger level for DSL could make use of BPL.

As mentioned above, there are rural towns that are not likely to get their exchange DSL enabled, and are unlikely to get wireless either but this would work quite well with enough of a population density to have plenty of subscribers per transformer.

You don't need to use licenced spectrum to provide Wireless Broadband - indeed, in rural areas interference on the 2.4GHz spectrum is probably a lot less trouble than it is in a built up area. (Not to mention that BPL equipment, because it's a timy market, is far more expensive than DSL equipment. Therefor any vuable "trigger" for BPL would be far higher than it would be for DSL).

(and yes I know a government sponsored scheme for satellite broadband is available in Caherciveen .... but its satellite, nuff said)

Just think about that for a minute - if they have to use satellite to get data into Caherciveen in the first place, then what good would BPL do you? What the hell would it distribute to the last mile?

WTF are you wittering on about ... I was talking about a well known technology that has been seen working and you start about water pipes .....

Except that it hasn't been seen working on a commercial basis - it's been trialled a number of times, and every single time, it's been dumped as just not feasible. (As far as I know - are there any commercial deployments of BPL anywhere?)

As mentioned above, there are rural towns that are not likely to get their exchange DSL enabled, and are unlikely to get wireless either but this would work quite well with enough of a population density to have plenty of subscribers per transformer.

"Unlikely to get wireless"? If they aren't likely to get wireless, it must be because nobody thinks it's worth their while providing it - what makes you think that the ESB would be a better choice, given that wireless gear is far cheaper than BPL, and has a longer reach?

iwb

This is the closest to a commercial implementation that I am aware of. It is still a trial but has been for quite some time. The caveat is 'The eventual launch of this service will, however, depend on the technology meeting regulations set out by the Radio Communications Agency and European Commission.'

Powerline is a holy grail like Nuclear Fusion, it will be fabulous when it works but realistic only if it works without intefering with radio spectrum.

This has proved in experiments over the past 10 years to be an impossible hurdle to surmount without spending a fortune. Arguably it could possibly be cheaper to wrap lines in fibre instead out to the home than to isolate PL tech in order that it not interfere with the RF bands long used by experimenters (40Mhz ish IIRC ) . That will simply not happen in our lifetime.

We are really left with Wireless and ONLY Wireless as a feasible economic technology to deliver BB outside Urban areas.

Those who have long been Wireless Experimenters have the right to usage of the airwaves ...... a long established right of way ........ and probably won the argument about it before the trial in Tuam went live.

It will erupt again but in the absence of a huge qualitative leap in filtering and interference suppression (100x better) it is a dead duck in this country ...... IMO

I speak as a holy grailer who has seen the light

Just think about that for a minute - if they have to use satellite to get data into Caherciveen in the first place, then what good would BPL do you? What the hell would it distribute to the last mile?

There is fibre laid to (not through) smaller towns all over ... and anyway, microwave is a viable data transmission medium that is currently in use all over the country.

See above ... there are towns with large populations up and down the country that dont have WISPs ..... and wrapping a fibre around some of their overhead wires is a hell of a lot cheaper than putting it in a hole in the ground....

It is cheaper by a factor of 5-10 to wrap fibre rather than bury it, especiallly on the west coast where you get that granite schtuff lying around.

Wireless is cheaper by a factor of 5 to 10 than fibre wrapping ........and looks likely to get cheaper again .

Given an effective range of 300m, the population density would need to be pretty high before the costs spiral out of control. Wireless can cover kilometres at extremely low cost.

Right .... and that purely circumstantial evidence proved what?

A hell of a lot more than your vague reference to "technology that has been seen working."

The funny thing is, you're not even being consistent:

microwave is a viable data transmission medium that is currently in use all over the country.

So, which is it? Can wireless cover the country or not?

You really aren't very good at putting 2 and 2 together and getting 4 are you?

The reason that there aren't WISPs in every little town and village is because not many people are convinced that there's a viable market worth serving. Is that hard to understand? And if there aren't enough people interested to make Wireless commercially viable, there sure as hell won't be enough to make BPL commercially viable. Or did you expect someone else to subsidise it for you?

Of course, the situation is slowly changing - the companies that are beginning to show up to deliver Wireless broadband outside the cities (lastmile, digiweb, KCS, to name 3 off the top off my head) are making steady progress, building up their experience, and their coverage. But they still need to know that there is an audience for their service before they will invest in an area. The Group Data Schemes have also demonstrated that Wireless delivery of Broadband can and does work in rural areas - and at an affordable price (but you won't get a GDS unless the end users put their money where their mouths are _before_ they get the service, which makes the success of Knockmore all the more encouraging!)

There is fibre laid to (not through) smaller towns all over ... and anyway, microwave is a viable data transmission medium that is currently in use all over the country.

That's exactly my point! The "South West Broadband Initiative" is using Satellite to deliver data into Cahirciveen, and it is then distributed using a WLAN in the town. In other owrds, they're using Wireless for the bit that BPL would deliver, the last mile, and have decided to get their backhaul via Satellite. Even if they used BPL instead, they'd still have to get their backhaul from somewhere, and BPL wouldn't make any difference to that.

Didnt I read somewhere (possibly here) that there is a business doing it in Germany

God only knows what you read. It's not going to provide much support for your argument if you can't find the reference yourself, though, is it?

See above ... there are towns with large populations up and down the country that dont have WISPs

And how many of them have BPL?

The FAQ still says
"Do you have any future rollout plans for other customers in your area?
We are in advanced stages of our trials on a technical level and early stages on a commercial level. The results of the pilots in Stonehaven, Crieff and Winchester will shape our future rollout plans. The Stonehaven trial started in July of last year, so that sort of puts the Scottish-Hydro site in the same league as NTL "Get broadband from us!!!" (if you live in a few selected areas....)

OK ...enough of the anecdotal "BPL is really expensive" ... show me a price list (/me waits for the zealots to find the most expensive BPL cost possible compared to the cheapest wireless cost)

A hell of a lot more than your vague reference to "technology that has been seen working."

Right, noise floor increases (alarmingly so according to some interested parties) and this is immediately pinned on something that said interested parties believe to be a threat to their spectrum ...hmmmm bit of a coincidence that...
You compare this to trials that do actually what they were designed to do ..i.e. provide broadband to customers and call the technology vague ..... I dont follow you there

The funny thing is, you're not even being consistent: So, which is it? Can wireless cover the country or not?

I was referring to the point to point wireless links put in place by Eircom .... when eircom removed the multiple phone lines linking exchanges all over the country they sometimes put in microwave links (called microwave, but I think they use a much higher frequency) for a lot of the links between exchanges and got an external company to reclaim the copper hanging off the poles.

I think its all about cost, DSL ISP's companies are eating the cost of connecting customers but WISP's arent ... if the ESB took over the costs of installation they would be a serious contender for most people who want broadband. How many people would avail of broadband per 1000 is not something easily found out and varies from area to area, what makes sense in Leitrim may not be true for Wexford ... broadband in every primary school will be a big driver for broadband uptake I think, more potential customers may get the WISPs to get the finger out, but I'm not holding my breath...

That's exactly my point! The "South West Broadband Initiative" is using Satellite to deliver data into Cahirciveen, and it is then distributed using a WLAN in the town.

Indeed, WLAN to distribute the satellite feed is a good plan and easy to implement ... but if the ESB were going to offer bpl they would wrap some fibre around their cables and bring bandwidth to where it could be distributed ... I really dont envisage any company using bpl to redistribute a crappy satellite connection

God only knows what you read. It's not going to provide much support for your argument if you can't find the reference yourself, though, is it?

couldnt be arsed spending ages trying to find it ....but it was definitely mentioned in a post on boards.ie .... just because I dont link to it does not mean it doesnt exist

And jebus, would people stop with the wireless will sort out everything .... it is _A_ possible way of getting decent low latency bandwidth into peoples homes ...


Right ...I'm off to bed .... just cant wait for some more good vibes in this thread ... makes me feel all warm inside.

There's a good one! Someone calls himself "BigEejit", lives up to his own name, and then gets all huffy when people try to explain things in very simple terms because he's repeated demonstrated that he doesn't have a terribly firm grasp of the bleedin' obvious.

Right here on boards.

And do you claim to understand the ESB's business plans, and what they think is viable and what isnt? ... enough conjecture please, ESB may or may not extend their trial and if they find that there is good uptake and more importantly, if they find there is lots of money in it they will push for it with the government.

Hey, if you want a moratorium on any discussion of BPL until the ESB make their mind up, then go ahead and shut up, nobody is stopping you. Or do you want every one else to stop, while you continue with your fact free ramblings?

OK, its not viable for BPL and it is for wireless, not the only one with 2+2 problems ..... why are there places where the arguably more expensive DSL is implemented and its well subscribed and wireless isnt available at all?

DSL isn't expensive to implement!!!!! Eircom can hardly keep up with the demand in the areas that they have implemented it, so they have no need to accelerate their rollout program. And the companies that are rolling out Wireless are actually making faster progress than eircom did with DSL, but those that are servicing areas outside the cities are focussing their resources on the areas that they can properly support. They're not rolling out wirleless broadband out of some sort of mission to bring broadband to the masses, the're commercial enterprises, out to sell a service. They won't do themselves, or their paying customers any favours by over extending themselves.

Indeed, WLAN to distribute the satellite feed is a good plan and easy to implement ... but if the ESB were going to offer bpl they would wrap some fibre around their cables and bring bandwidth to where it could be distributed

'sfunny, I could have sworn that someone with a name very similiar to yours said something about "There is fibre laid to (not through) smaller towns all over " - there is no need for the ESB to bring any more fibre to these places, it's already there! If wrapping fibre would be cheaper than buying their backhaul from someone else, why aren't they wrapping fibre today, and selling that backhaul themselves? (Yes, I know about the figure-of-8 networks).

And jebus, would people stop with the wireless will sort out everything .... it is _A_ possible way of getting decent low latency bandwidth into peoples homes ...

Personally, I'd chose a wired link over a wireless link in most cases - but BPL is a dodo that doesn't have _any_ advantages over wireless in rural areas, and only makes sense in reasonably built up areas, where DSL is already likely to be an option.

Just cant help thinking how different this 'discussion' would be if 802.11b was a threat to the ham radio frequencys and bpl wasnt ....

FFS - did you bother to stop and think _WHY_ 802.11b isn't, and couldn't possibly be a threat to ham radio frequencies?

I agreed with you. Pay attention.

not too far from you... Tuam I believe

Woo, BPL works in an environment where (a) DSL would have worked just as well, and (b) WiFi could have achieved the same thing at a fraction of the cost and without making **** of the HF spectrum. Excuse me while I'm underwhelmed.

Maybe I overstated a little here, I remember a discussion here before and someone provided a link to a german company offering BPL on a larger scale than normally associated with "a trial."

OK ...enough of the anecdotal "BPL is really expensive" ... show me a price list (/me waits for the zealots to find the most expensive BPL cost possible compared to the cheapest wireless cost)

I think you're mistaking me for someone who gives a rat's ass what BPL costs: it won't work for the bulk of the geographical area of the country, so it's not interesting. BTW, I know exactly what it costs to provide wireless coverage to a rural community. I haven't seen any figures for BPL yet. I'm willing to bet my solution is cheaper though.

Right, noise floor increases (alarmingly so according to some interested parties) and this is immediately pinned on something that said interested parties believe to be a threat to their spectrum ...hmmmm bit of a coincidence that...

It's not a coincidence. BPL raises the noise floor. Everyone knows this. If you have evidence that it doesn't, please post it.

You compare this to trials that do actually what they were designed to do ..i.e. provide broadband to customers and call the technology vague ..... I dont follow you there

Actually, I called you vague. Pay attention, please.

I was referring to the point to point wireless links put in place by Eircom .... when eircom removed the multiple phone lines linking exchanges all over the country they sometimes put in microwave links (called microwave, but I think they use a much higher frequency) for a lot of the links between exchanges and got an external company to reclaim the copper hanging off the poles.

You can wave your arms until the cows come home, but you're just proving my point. Wireless provides a cheap way of getting bandwidth to where it's needed.

Just so we're clear, I'm with Ripwave: I'd rather a wired connection any day. But until some kind soul decides it's a worthwhile exercise pulling a fibre to my doorstep, I'll continue to explore the capabilities of wireless.

I'd like everyone to just take a step back for a moment. Breath in through the nose slowly, and out through the mouth. Repeat a few times. There now, don't you feel much more relaxed? Good.

There's no need for the aggresive tone from either 'side' here, so let's not have handbags at five paces unnecessarly.

That is all, carry on.

Theyre zealots, cant help themselves ..... oh the warm fuzzy feeling you get when being personally attacked by a bunch of ..... ....... ok, I wont classify them/him, taking Moriartys advice ... breathing deep ..
