However, these high-performance routers still use the traditional architecture of "wired power supply + Ethernet backhaul": the router must be placed near the information box or weak current cabinet and connected to the optical modem through the pre-buried Cat5e / Cat6 cables in the wall; when providing gigabit coverage in multiple rooms, additional network cables still need to be laid to each panel AP or Mesh node, and the construction requires drilling walls, running conduits, and drilling RJ45 connectors, which is difficult and costly to modify in already renovated houses.
