Hey, A friend of mine is currently building a house and we are going to put networking cable in his walls (CAT5). I was woundering if the cable got much interfierance from power cables in the wall/frame. If so how do we avoid this he is insulating and so far we have put the power on one side and the networking on the other.Is This enough? Thanxs in advance Slorg

Yes, you can get interference from the electrical wiring which is why, as much as possible, you want to prevent running the network cables parallel to the electrical wiring. If you must run them parallel to each other, try to keep the cables at least 12 inches apart. If you want added protection, you can run the network cable through conduit for the sections that are running parallel to the electrical wiring. Your friend may want to look into running bundled cable instead of the single cat5. Bundled cable (also called structured) is several types of cables bundled together and comes in several configurations. One common configuration includes 1 fiber, 1 RJ6 coax, and 2 cat5e cables. This will provide him versatility and expandability with only a small increase in material cost.
