RE: [backstage] Is this BBC Homeplug product legal?
Router upstairs in back bedroom. Freesat set top box downstairs in living room. Master phone socket at the bottom of the stairs. Homeplug's far easier in such a scenario - which is the scenario in my house. Freesat are a joint venture, 50% owned by the BBC and 50% owned by ITV plc, so it's not really Auntie's brand. They have taken the decision to inform the public that there are different ways to connect their set top box using the various available methods - ethernet, Homeplug and wireless bridge. All are legal and valid at this time.

The RF noise generated by these technologies is quite bad, it's in a band where noise can propogate worldwide via the ionosphere. It can prevent receivers locking to, or demodulating a signal. http://downloads.bbc.co.uk/rd/pubs/whp/whp-pdf-files/WHP116.pdf Also, it's very easy to demodulate the Ethernet traffic radiated from your house wiring from one of these systems - it's not very secure!

Wasn't encryption an option on Homeplug 1.0? I thought it came with either a default password or the option to switch it on.

RE: [backstage] Is this BBC Homeplug product legal?
Usually one wire, singular. With HomePlug I can have ethernet wherever there is a power point, and I do move them around now and then. Can I cast my vote for a 20m CAT5 cable under the carpet, up the stairs, to a discreetly placed gigabit switch on the landing / in the study? You still only use one power socket, way better throughput and far less annoying to our radio ham friends =) and everyone likes ducting CAT5, right? Those flat CAT5 cables look like they could do the trick nicely, but I'm more a fan of the 'just wind it around the banister' method ;) turn your network infrastructure into additional decoration! - Sent via the backstage.bbc.co.uk discussion group.
