I want to broaden my home network from downstairs (2 stories up) to the attic. Problem is that there is not a wiring pipe running from downstairs to the attic. I thought about networking through the power net, which seems to be working alright since there are several companies making and selling it. The speed of that is 85mbps, against the regular 10/100Mb/s capable router and switch. Now, I want to place a webserver, hosting my personal website, in the attic as well. Besides the webserver there will only be installed a separate network for testing purposes, consisting of 1 server and 2 workstations (which will run several instances of virtualpc each). The separate network will functioning entirely on its own, so there is nothing to worry about on that. Still though, I'm a bit worried on the speed of 'powerlan'. 85Mbps against 100Mb/s is quite a difference. Calculations remind me that 85mbps is nearly 10Mb/s... The connection with my ISP is 20Mb/s, which rules out most doubts I have. One last thing I really need some heads up about, is this: 1. Do more devices on the electrical network actually cause more noise on the 'powerlan'? 2. If the 'powerlan' is only 10Mb/s, that's obviously splitted through the entire attic network, will it be noticable? The server upstairs will be connected to the internet as well, providing the workstations with a web connection as well. 3. Is 10Mb/s (from up- to downstairs) enough for the webserver to function properly? Below is a diagram of what it will look like if the idea passes.
