What type of wires or cables should my electrician use?

CAT 6 is considered a superior network. Having said that, to date, both CAT 5e and CAT 6 are supported. CAT 6 cables are designed for operating frequencies of up to 250 MHz, offering speeds of up to 10Gbps in comparison to the 100 MHz and 1Gbps speeds with CAT 5e. This means that a CAT 6 cable can process more data at the same time.
