Networking:

A data network sounds rather complicated but is in fact is just a load of wires around the house to allow phones and broadband to be accessed in each room in the house.

A lot of "smart wiring" companies feel this is sufficient to be cutting edge and include the tv distribution system on this network. This is The CAT5 cabling that everybody claims is all you'll need.

It is very frustrating the amount of times we have met with a builder who claims "I don't need you guys sure I've CAT5 everywhere". The myth and confusion of Smart wiring continues.
