/*
|
|
* A part of the work of GeckoNetworkManager is to give an estimation of the
|
|
* download speed of the current connection. For known to be fast connection, we
|
|
* simply use a predefined value (we don't care about being precise). For mobile
|
|
* connections, we sort them in groups (generations) and estimate the average
|
|
* real life download speed of that specific generation. This value comes from
|
|
* researches (eg. Wikipedia articles) or is simply an arbitrary estimation.
|
|
* Precision isn't important, we mostly need an order of magnitude.
|
|
*
|
|
* Each group is composed with networks represented by the constant from
