connectiontype 3 means Cellular Network - Unknown Generation

When to send it

Send 3 when the device is on a cellular network but the generation is not known. Mobile web requests often land here, because a browser tells a server little about the radio, and some app platforms restrict access to network details.

Buyers treat 3 as generic mobile data, and those that adjust creative weight by network speed assume a middle case. Prefer 4 to 7 when the platform reports the generation, but do not guess: a request that says 6 for a phone that is really on 3G invites a creative that buffers. It is also the safest value when the generation changes during a session.

Example

{
  "device": {
    "connectiontype": 3
