People have been calculating bandwidth on their own successfully for a long time, I’ll look at the code and see what my be different here.

At the risk of taking this far off track, maybe this would be a good lunch time discussion. Bandwidth is necessary, but not sufficient, for fully understanding underlying network characteristics.

Blake,

Please look at requestBandwidthUpdate() coming up in Android M as an API of exposing available capacity on the radio downlink.

No Operator would share that kind of information from their base station. That is a non-starter. The base stations are busy with what they usually do best - delivering as many bits as possible to the UEs attached to it.

Vijay

I’ve had discussions with carriers that would contradict that statement.
