 // EffectiveConnectionType is the connection type whose typical performance is
 // most similar to the measured performance of the network in use. In many
 // cases, the "effective" connection type and the actual type of connection in
 // use are the same, but often a network connection performs significantly
 // differently, usually worse, from its expected capabilities.
 // EffectiveConnectionType of a network is independent of if the current
 // connection is metered or not. For example, an unmetered slow connection may
 // have EFFECTIVE_CONNECTION_TYPE_SLOW_2G as its effective connection type.
