PLC banned in Finland – many complaints

Session held on PLC in the Finnish Telecommunication Administration Center (Telehallintokeskus, THK) on May 16 th , 2001.

The Finnish Minister of Transport and Telecommunication, Mr. Olli-Pekka Heinonen, had answered to the question of a Member of Parliament regarding the introduction of PLC in Finland: For the present, because of the technical problems encountered, introduction of PLC technology is not possible.

THK had invited current and possible future users of radio frequencies for a session to discuss the introduction of Power Line Communication PLC.

Participating bodies of this session:
• Telehallintokeskus, THK (Finnish Telecommunication Administration Center)
• Jyväskylän Energia OY (Regional energy network operator)
• Sähköenergialiitto r.y. SENER (Association of electrical energy network operators)
• Pääesikunta (Headquarters of Finnish Defence Forces)
• Ilmailulaitos (Finnish Aviation Administration)
• Digita OY (Broadcasting transmitters operator, operating the transmitters of the Finnish Broadcasting Company YLE)
• Suomen Radioamatööriliitto SRAL r.y. (Finnish Amateur Radio League)

The energy suppliers expressed their interest in using the frequencies for data traffic. They also expressed that with modern equipment, in their opinion the radiation by PLC on their networks would not be above natural noise.

The representative of the Finnish Defence Forces deems usage of the same frequencies in the air and in power cables without interference impossible.

The representative of the Finnish Aviation Administration expects safety risks if PLC were taken in use.

The representative of the Broadcasting transmitters operator Digita OY expressed that the limits in the German standard NB-30 are too low for the operators of PLC and too high for the current legal users of the frequencies.

He assumed that usage of PLC would totally stop home reception of analogue and digital broadcasting transmissions on the HF bands in the normal home.

The President of the Finnish Amateur Radio League deems PLC a threat to all users of radio frequencies, and said that the published results of tests had showed that PLC presents harmful interference to radio frequencies.

He expressed that technology can develop further but that the laws of physics do not change.

The common opinion of all the participants of the session was: PLC technology can only be taken in use, when it has been thoroughly proven that PLC does not present harmful interference to HF radio traffic and especially to safety relevant HF radio traffic.
 
The EU says YES to Powerline

I am not familar with the Finnish power distribution system but it may well be different to the UK's. There is again no evidence of Interference just assumptions. The information quoted is also very old and presumably referes to Generation 1 equipment which did have problems and did not comply with the EU EMC directive.
The 2nd Generation equipment has had no interference problems at all. The Third Generation due out later this year will offer further improvements although the generation 2 is already compliant.

I challange you to come up with a single documented report of Interfernce being caused by Second Generation Powerline equipment.

You will not because you know there are no issues.
 
I could be wrong here, but isn't it only being tested in rural Scotland at the moment in the UK ? Interference may only be a problem in more built-up areas.

PLC - safety risks - Finnish Aviation Administration

Finland – “The representative of the Finnish Aviation Administration expects safety risks if PLC were taken in use.”

Actually the Finish electrical system is almost identical to the U.K. and the same conclusions apply.

The RSGB report on Crieff in Scotland clearly shows that the current U.K. implementation of PLC is seriously flawed and has interference problems;

PLC -

I don`t see what the problem is. The Manchester trial had troubles, but that was _ages_ ago with early equipment (in the 90s if I remember correctly - update: 1998 to be exact).

The current trials - far from being shut down - have indicated there should be a further roll out.

If there are major problems the roll out will be stopped. Why are you so wound up about it ?:shrug:
 
5 trial areas currently, Crieff & Campbell town in Scotland both small towns another very small pilot trial in Maidenhead. Two large trials just started one in Stonehaven in Scotland population about 10,000 and looking to have 400 triallest, the other trial is Winchester, population anout 110,000 looking to have 1000
triallests.

The last two are major large scale trials the outcome of this will decide the Rollout strategy

There are many other trial in Europe & commercial deployment. Germany has a number of commercial deployments of it.

If it is 7000 Rural users it is 6999 more than our friends at BT can manage, Power to Powerline if they can do better and that would not take much effort.
 
Re: PLC - safety risks - Finnish Aviation Administration

Safety risks, you must be joking, there is zero chance of that.

You better give up using anything mains powered its far too risky for you.

PLC just say no said:
