    Hi Folks,

    I currently live in an apartment block and I'm curious to know what sort of limitations these "Network adapters over the electricity lines" have, i.e. if I plugged one into my apartment, and another into the apartment above me, could I create a network ?

    OR

    In the hallway of the block I live in, theres a power socket, in the next block over, is a power socket - could I technically plug one of these Mains network adapters on either end and create a Network between the buildings ?

    cheers

    My 2 cents on the matter

    You'd need power modems (eg FSK power modems) and isolation transformers to start with. (not sure if they are in-build into the device you mention - however assuming they are#)

    I did it a few years ago between two PC's over power lines between different rooms, problems such as
    changing impedence levels on the power lines - eg someone plugs in a device and it effects the meduim of transmission

    The baud rates arent all that good anyhow! it would be far more effective and cheaper to use wireless or bluetooth

    As far as I know they only work over the same electrical circuit. It's hard to know whether two sockets are on the same circuit or not.

    Google homplug and check out a few manufacturers websites. They defo can be better than wireless. May or may not work tho! Think they're rated for 200Mbps now. 802.11g (normal wireless) is 54Mbps, and the upcoming wireless standard (802.11n) is slightly faster at 300Mbps

    It's my understanding that with these devices, you must be on the same circuit, as RCDs & MCBs interfere with the transmission distance... however, I think it was GE that were doin an RCD to allow data transfer through it...

    Whatever about getting to another circuit in your own house, I woulnt say you could communicate from building to builing...or from your circuit, through the ESB Meter and back through the Landlord ESB meter to the landlord socket...

    Wireless might be a much better solution for you
