When to send it

Send 1 when the device is on a wired network. Desktop computers on a LAN, set top boxes, and smart TVs plugged into a router by cable all qualify. OpenRTB 2.0 to 2.5 labeled it Ethernet; the AdCOM label adds wired connection, which makes clear that any cabled link counts.

Buyers read 1 as stable, high-bandwidth access that can carry high bit rate video, and as a sign of a fixed location rather than a phone on the move. It is often confused with 2, because operating systems and SDKs do not always expose which local link is in use. When an app cannot tell wired from wireless, leaving the field out is better than guessing.
