The linkLatencyEstimate subsystem provides the client with APIs, to get link latency
        estimations for uplink and downlink. These APIs are part of smart data link.

Application vendors can configure and query the link latency estimation report and/or
            subscribe for report events. The report interval can be set with setReportingCriteria .
