What type of wires or cables should my electrician use?

We’d suggest you consider using CAT 6 cables – they’re really top-notch! These cables are built to handle frequencies of up to 250 MHz, supporting speeds as fast as 10Gbps, meaning they process more data in one go.

CAT 5e cables are also good to go. They can handle frequencies of up to 100 MHz and up to 1Gbps speeds.
