Yes. I have also used a single wireless unit (half the pair) as a Wireless Access Point by plugging an Ethernet cable between the router and the Ethernet socket.

Re: Homeplug/powerline ethernet

Hi all,

 

Resurrecting this thread.

 

I have a summerhouse about 50 metres down the garden. The Wifi barely makes it and if it does, the signal will drop completely.

 

So considering a powerline.

 

Now the powerline would connect to the modem, through two consumer units to the Summerhouse. So I guess to would definitely not work? If I could connect a wireless extender to a Powerline with a socket output beginning of the feed to the Summerhouse  with output at the end of feed to summerhouse before going into the small consumer unit, would this work or complete overkill? And what are my alternatives?

 

Bit worried reading the thread about RF emissions as well although maybe only exposed for three hours a week.

Re: Homeplug/powerline ethernet

Powerline might work - but why does a summerhouse need a separate consumer unit?

The outdoor cable should be a substantial piece of armoured, underground cable - totally different from house wiring...

So it would be trial and error.

If you have access to a suitable route, Gigabit ethernet cable (up to 100m) could be used... :smiley:

Ethernet cable is shielded, so you won't get killed off by any intense wi-fi rays.

It never ceases to amaze me that people worry about unsubstantiated scare stories about emissions from mains cables etc. but without a second thought are happy holding a mobile phone etc. to their ear.

Re: Homeplug/powerline ethernet

Yes. Sorry. Should have opened with the statement "Forgive the stupid question but........"

 

The feedback I have had would suggest that a Powerline would be problematic (not considering emissions) as it would be going through two RCD's.

 

So concluding a CAT 5.e or CAT 6 hard wired option and simply connecting up through a open window to a LAN output as and when required.

Re: Homeplug/powerline ethernet

It was a general observation, not intended to have a  go at you so sorry if it caused offence.

The Ethernet cable is a far better solution, especially considering the two RCDs in the circuit. It's also cheaper.

If you are prepared to do a bit of DIY and terminate the ends of the Ethernet cable then it's not a big deal to install the Ethernet cable permanently. Long masonry drills are available from the likes of Screwfix quite cheaply. Depending on the cable you use you only need a 5/6mm one. I have installed Ethernet around my house and have cables running through cavity walls with no problems. I have terminated these in fixed wall outlets on the inside and it makes a professional job of it.

Leaving an unterminated plug outside when you shut the window is bad news unless there is somewhere clean and dry to store it.

Re: Homeplug/powerline ethernet

A hard-wired ethernet cable should be permanently connected and installed so that there is no strain on the end-connections.

Get cable suitable for outdoor use - UV resistant etc.

Scoff all you like at the though of EM Radiation however last year I was a victim of it in a bad way: This is what the side of my face looked like for a number of months:

 

screenshot-989

 

The cause? A 1.5hr whatsapp video call on 4G. From that point on i noticed the side of my face burning substantially with an ice pack eventually being needed that evening. It became so bad that I was unable to go out in sunlight, near light bulbs and was barely able to use a computer - or a mobile phone because LIGHT.... yes LIGHT would trigger a flare up.

 

Before you dismiss it (as i know some of you will) I was referred by my GP (also a sleptic) to the local dermatologist. I explained it and the first thing she said was "that's the radiation". A biopsy was taken and sent to the hospital lab. The histology report came back saying that I had developed a hypersensitivity after they had exposed the cells to light in the lab and confirmed repeated reactions.

It's not so bad now but i still find myself starting to itch if i'm around too much light and yes, if i use wifi or 4G for too long I also find myself starting to itch too.

I need a new signature... i'm bored of the old one!

Re: Homeplug/powerline ethernet

Interesting 7up.

Yes, the radiation from a mobile is similar to that from a microwave oven, but at a much, much lower power - 1.5w versus the 800w of a microwave oven.

The actual power output of the phone, is very dependent on the distance to the nearest cell. The cell likewise uses a similar power to the phone, varying it dependent on distance to the phone. Such radiation follows the inverse square law - the level you will be subjected to, is 1/4 for every doubling of distance between you and the transmitter/phone/mast. 

What causes me considerable amusement is parents complaining about cell masts on schools and near their homes, due to radiation from the cell masts. Yet the very same parents allow their kids to make free use of mobile phones - completely failing to grasp that the more masts there are, the less the radiation their kids will be subjected to next to their brains as they use the phones.

Re: Homeplug/powerline ethernet

So a phone is transmitting at maximum power if it is getting a poor mobile signal - perhaps because the nearest mast is a long way away?

Re: Homeplug/powerline ethernet

Yes, the more distant the cell, the more power is needed by both ends of the link to sustain the connection. So your battery will use more of its charge in the process.

@7up 

I am very sorry that you have developed this condition. If you read my post you are in fact confirming my point. It is my argument that rf radiation from cabling is far less intense than you will experience from using a mobile phone.

I’m not interested in scare stories, I would like to see proper test results.

Re: Homeplug/powerline ethernet

Powerline signalling uses very different frequencies, less power and unlike a phone, you don't put the cable next to your brain. The biggest problem with Powerline signalling is the HF radio interference generated, particularly for those who attempt to use HF frequencies at low powers.
