Data point
Low Voltage · Also: RJ45 point, Network point, LAN point
In short
A wall outlet for wired network cable — still useful despite Wi‑Fi.
Notes
Data points (RJ45) give a hardwired network connection for mesh nodes, desktops, TVs, or work desks.
Run them while walls are open. Adding Cat6 later through finished carpentry is a pain.
