connectiontype 7 means Cellular Network - 5G
A fifth-generation cellular connection. It comes from the AdCOM list and is not in OpenRTB 2.5's table.
When to send it
Send 7 when the device is on a 5G network. The value does not exist in the OpenRTB 2.5 document, which ended at 4G; it comes from the AdCOM list that OpenRTB 2.6 references, so a bidder built on the 2.5 table may not recognize it.
Buyers treat 7 like 6 for most creative decisions, and some use it as a weak signal for newer handsets. Bidders that validate against the 2.5 table can reject 7 as out of range, which is worth checking with partners before a seller starts sending it. It is confused with 6 for the reason described there: some devices on 5G report the 4G anchor link instead.
