The technician has measured two characteristics using simple command-line tools that verify the problem. Based on the symptoms reported by the users, the two characteristics that the technician has most likely measured are latency and packet loss.
Latency refers to the amount of time it takes for data to travel from one point to another. In the context of VoIP, latency can cause delays in conversations, resulting in choppy and sometimes unintelligible audio. The technician may have used a command-line tool such as ping to measure the latency of the network.
Packet loss refers to the loss of data packets during transmission. This can be caused by a number of factors, such as network congestion, network errors, or interference. In the context of VoIP, packet loss can cause audio to drop out or sound distorted. The technician may have used a command-line tool such as traceroute or pathping to measure packet loss on the network.
Reflection, interference, signal-to-noise ratio, and attenuation are all characteristics that can affect wireless networks, but they may not necessarily be the cause of the problem in this scenario. Reflection occurs when wireless signals bounce off surfaces and interfere with each other, leading to signal degradation. Interference can be caused by other wireless devices or by sources of electromagnetic radiation, such as microwaves or fluorescent lights. Signal-to-noise ratio measures the strength of the signal compared to background noise, while attenuation refers to the weakening of the signal over distance. These characteristics could be measured using tools such as spectrum analyzers or signal strength meters, but they may not necessarily be the cause of the VoIP problem in this scenario.
