Interested to know why people are using satellite.

Is it your Exchange is deemed Unviable ?

BT have not set it a trigger level ?

You are to far away ?

TPON ?

Other ?
 
Need it for my business. I am running a local campaign to DSL-enable my exchange. BT has yet to review the exchange to set a trigger level so it's not unviable - 225 registrations so far.

Depending on the outcome there may be a lot of SM customers in my vicinity!

Supposedly BT review them ones 200 pre-registrations are reached but it seems to be a bit hit and miss. I would think BT will set some more triggers before christmas but who knows with them. They are not exactly consistant.

Apparently BT will review exchanges above 150 now as this is the lowest trigger level they set.

The process is slow and painful. But I've been delighted with satellite as I thought I was destined for 128 max with ISDN.

My exchange and ADSL Campaign has 177 pre-regs but no target. Deemed unviable despite a smaller exchange 2 miles away having a 150 target and only 80 pre-regs.

I'm hoping that we get a target about Xmas as WebBuddy alludes to.

I'm on Sat because I can't get anything else. My line is fine for 2MB ADSL and that's what I'll be having as soon as I can get it!

My "local" exhange is ADSL enabled, however I'm (apparantly) 10km from the damn thing. Irritatingly there is a closer exhange, but I'm not on that one and according to BT cannot be transferred to it either.

That's why I'm stuck with satellite (until Southern Electric get going with their broadband powerline system - and then I'm off)
 
10Km is dahm long even for voice. Have they put amplifiers on the line.

If you can find any cause to complain about the quality of voice cals such as too quiet etc have a go at BT they have to fix voice problems.

For me there's currently no other option, although I'm hoping Hydro Electric will bring the powerline doofer to my neck of the woods. There's very little chance of the exchange being ADSL enabled in the forseeable future so really like everyone else I'm here because there's no alternative. Satellite is definitely at the bottom of my list of ways I'd want to connect to the Internet.
 
Powerline is still a new technology. I am pretty certain that Powerline will happen, most if not all the problems have been resolved although no doubt the technology will continue to evolve and be improved further. The next step will be to drive costs down.

The intersting thing will be if they can as they say deliver the higher bandwidths if they can it gives them a strong comptitive edge over BT who can only deliver 512K to about 40% of their subscribers.

May not be much demand for over 512K but by the time Powerline hits the market big time there could be.

There are more and more companies getting into Powerline. Yes there will be some casulaties and some will drop out and I am sure one or two more technical challeges will be hit along the way but Powerline will happen its just now a matter of when.

I, to be honest, can't see power line broadband taking off in any big way. There's a major problem with it, which will soon come to light once amateur radio enthusiasts have it set up near their areas.

Have a look here for a rather large argument against power line broadband, and several reasons why it can't and won't reach rural customers:

I think there are a lot of exciting developments potentially ahead for satellite e.g., launch of cheaper two-way satellite services. Once players like BSkyB get involved and are able to offer combined broadband/TV packages and installation, then we may see broadband satellite really motoring. At present, satellite is not a true mass-market proposition, but it will be interesting to see how companies like Silvermead can address this.

It's clear that there is now significant satellite over-capacity. With more efficient video coding schemes around the corner (MEPG4 AVC) together with failure of smaller TV channels, satellite owners are going to be desparate to fill up their satellite with broadband services.

These claims do not actually corralate against the field trial results. Emissions are at an acceptable level and in some cases below those of ADSL. They are certainly far better the VDSL can currently achieve. Development of the technology is still ongoing so emc is not an issue. The EU & FCC have already provisionally approved Powerline.

I'm 7.2km from the exchange :(

We have cable though, trouble is it was layed by Eurobell, who were brought out by Telewest. The system is analogue aparently and Telewest havn't got the money to upgrade it allthough they do have to money to rebrand eurobell and send be a bell that says Telewest Broadband Eurobell every month :mad:

The cost of Satellite will always be high. Two Satellite is particularly difficult. Unless some low cost way is found to get Satellites into orbit costs will not fall.
There is no excess capacity of Satellite Bandwidth. Any bandwidth is easily resold.Considerable chunks are used for telecoms.

Satellite will never figure as a big player. Its a niche product with Broadband catering for people who cannot yet get Cable, ADSL, Wireless or Powerline.

Ask almost any Satellite user and if they could get any of the above they would ditch Satellite. Its a poor choice for Broadband, the problem at present is many people have no choice.

The Satellite Broadband market is small and shrinking a number of players have already dropped out. Most are in the market for the goverment handouts for SME Broadband.

I tend to err on the side of caution, at least for now. Even if interference issues are sorted out, they'll always remain much higher than xDSL related technologies because of the physics involved. Electrical wires aren't "balanced" in the same was as twisted copper pairs are, so there'll always be a leakage.

There's plently to corralate against field tests. I refer you to some instances where power line technology was deemed unviable:

Finland (due to poor performance & EMC issues to radio users )

Netherlands (not cost effective, Interference issues )

Japan bans PLT systems (interference to radio users)

Italy
All trials ceased, no further trials planned

Hungary
It is not anticipated that Power Line Technology will be introduced into West European Countries for some time.

Poland
No further trials are being held in Poland

In Germany the trials not going well, Siemens stop manufacturing PLT equipment, poor real world performance of the mainnet system. See updates at

Nearly all those reports are very old and based on the old Norweb Technology.

Your statement vis xDSL being better then Powerline is not correct. VDSL poses some very nasty emc issues. Whether they would in practice cause interference remains to be seen.

Japan has not banned Powerline & field trials there are ongoing.

Several major manufactures have recently moved into Powerline. Large scale trials are under way in the US, Australia, UK, Korea & Hongkong as well as most other EU countries.

Powerline has provisional EU & FCC approval.

Yes at this stage costs will be an issue, these will come down as Powerline moves to full scale rollout.

There are no documented cases of Powerline causing interference.

Have a look at these vids posted elsewhere in the thread:

http://216.167.96.120/BPL_Trial-web.mpg 24MB MPG

the second is

http://216.167.96.120/BPL_Trial-small.mpg 7.5Mb

VDSL may leak, but nowhere near as much as PLT over electrical cables. Twisted copper pairs will ALWAYS be fair less suceptible to leaking EMC. They're pairs, meaning signals tend to nullify each other cutting down on outward interference. Electrical cables aren't balenced, as they're effectively one big wire.

Darn it, I love debates like this. They're so healthy for boards like these. Someone else come on into the conversation!
