It would actually be interesting to find out the percentages of people who predominantly listen to radio on:
FM DAB Internet Freesat Freeview LW, MW and SW. I suspect the latter will be in single figures..... My in-laws live in a stone farmhouse where (a) WiFi does not travel well and (b) has thick stone walls and wood beams so it is challenging to wire the house up with ethernet..... and (c) it is actually cheaper to use the mains networking than wiring up. So mains networking allows their smart TV in the lounge to connect to the fibre router in the office upstairs. The distance between the two is less than 10m but just one stone wall blocks the WiFi completely. This is despite living in the countryside and there are no other WiFi networks from neighbours as there aren't any neighbours! |

Not in stone, no, but if you have a raised floor and drylined walls well its not impossible... If the walls are plastered onto the stone, well you need to chip out channels and re plaster The ex wanted the TV moved: I lifted the laminate and used an angle grinder to cut a channel in the screed and buried the coax in that. I will need to run more cat 5 here soon to replace the mains power link: that will mean ripping off a few square feet of plasterboard, a very long drill and replace, skim and paint.

So all this guff from the router makers about fractal aerial design to
improve penetration of walls is rubbish, then they try to sell you a mesh system instead. They all forget the one major problem with wifi, that being the return signal from the devices, and how they have no control over that at all. I'm not saying that there is not an obvious use case for using the mains, I'm just saying that its a very very bad idea due to what it does for interference levels. What you need is some kind of system like a leaky feeder which you can wrap around the outside of your house. Brian -- ----- -- This newsgroup posting comes to you directly from...

Not just a case of drilling a solid stone wall.
It also means moving the furniture in upstairs office, lifting the carpet, pulling up floorboards.... Ditto in the master bedroom which is above the room with the smart TV in. Also lift carpet and floorboards in landing. The office is above the kitchen which is the room next door to the smart TV. In a property this old, there is no dry lining so it's all thistle browning and bonding plaster. All the beams are solid oak. Too much labour involved to put in 10m of ethernet cable. Even running ethernet outside is not viable as there is a 10m rum from smart TV to the outside wall and it would have to be weather rated ethernet cable. So I can see why a 40 quid set of mains ethernet wall warts are cheaper and quicker than both the labour and materials involved in doing the cable run. |

P.s. the kitchen floor and the floormof the smart TV room are tiled so have no carpet or laminate or floorboards to put back down either!

When they bought the farmhouse in the 1970s, all the old plaster was falling off.
So it was stripped a d replastered. |

I think we are making ourselves a serious problem. You are in effect making
a huge chunk of the radio spectrum unusable. Mains cabling was never designed to be used like this and huge powers are used due to the losses in the system and interference caused by other devices plugged in. If you want a cable then run it round outside the building then? Most of the interference from the plug adaptors is from about 4mhz up to about 32mhz, they have filters fro the ham radio bands but not for the international short wave bands. The eternal ticking and screeches even about 200 yds away is ridiculous. The other problem is the switch mode power supply. In the old days they were analogue with large heavy transformers but did not create interference. More usually these days there is a very crude rectifier directly on the mains running a high frequency oscillator of dubious purity and a tiny transformer and the other side is then controlled and used to drive your gear. It is far more efficient and if designed without saturating the ferrite transformer and with proper suppression components need not be an issue but it is because they makers pair down the design to such an extent it is just a jammer. Worst ones are often laptop chargers and some led lamps from China. Then there is ADSL once again forcing very high data rates along unscreened twin wire connections originally designed to only carry voice frequencies. These produce an alternating whining noise and a hash over the whole lf bands. When they are underground its not so bad of course.

To Brian,
In all fairness, I would not like my Freeview or Freesat to be affected in the same way as on LW, MW or SW. As a born profoundly deaf person, I rely on the subtitles and pictures working just like you rely on radio working as it's our link to the outside world. So I don't use power line networking at my house and just have the minimum of WiFi so that's just tablets or smartphones. Everything else is all ethernet wired, even the music systems, all smart TVs, all printers and scanners, all network storage etc. The loft looks like a data centre server room as a result, with over 64 co-ax cables and over 64 ethernet cables coming in |
