Generally, aggregation is governed by BTS and it is BTS who ultimately decides whether to enable it, and if so, at what speeds. Unfortunately, this is how it works. Generally, there must be some signal for the mast to activate the aggregations, i.e. to download data. On the other hand, as it will happen in every case, when and at what speeds aggregation will turn on and at what moment - it has no influence on it.
With full aggregation, the aggregation speed may be the maximum sum of the speeds of the individual bands.
