| Example Access Delay Measurement Data | Unknown | Example measurement results from the Mission Critical Voice (MCV) Quality of Experience (QoE) access delay measurement system. Access delay and mouth-to-ear latency combine to describe end-to-end access time. In particular access delay describes the minimum amount of time a transmitting user must wait between pressing PTT on a device and starting to speak to ensure that the start of their message is not lost. | Open resource |

| accessTime Repository | Unknown | The purpose of this software is to measure the access delay of a push-to-talk network. Access time generally describes time associated with the initialization and assignment of channels upon user request to speak and has been identified as a key component of quality of experience (QoE) in communications. NIST?s PSCR division developed a method to measure and quantify the access time of any push to talk (PTT) communication system. | Open resource |
