Re: [Marnew] RFC 6077

Certainly I think that info pertaining to the cell (or cell cluster) as a whole is best managed at the RRC, the dedicated radio resource controller within 3GPP networks. As Cameron says that aspect is too dynamic and ephemeral to effectively share. But there may be cases where the Android API can provide a coarse hint that is useful,  would be worth testing that.

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.
