Wiring installation is an effective way and important key for a good network transmission. 
No matter how good the equipment or how high the network bandwidth is. It’s like having a supercar that can’t perform its capability in narrow lanes, so we often call wiring like road paving. 
High frequency is like a sports car track, so the selection of materials must be certified by a third party, and must be implemented according to standards.The wiring layouts must be correct to meet the bandwidth and speed requirements.
