NetworkInformation: downlink property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Note: This feature is available in Web Workers.
The downlink read-only property of the
NetworkInformation interface returns the effective bandwidth estimate in
megabits per second, rounded to the nearest multiple of 25 kilobits per seconds. This
value is based on recently observed application layer throughput across recently active
connections, excluding connections made to a private address space. In the absence of
recent bandwidth measurement data, the attribute value is determined by the properties
of the underlying connection technology.
Value
A number.
