3.1.2 Timers

In the Proximity Detection operation, the host and the device exchange UDP messages in an attempt to determine the latency between them. If the latency is more than 7 milliseconds, the device is considered too far away from the host, causing this operation to fail. See [MS-DRMND] sections 2.2.1.3, 3.1.1.4, 3.2.5.2, and 3.3.5.2 for more details.
