Final answer:
D. Spectrum analyzer The most suitable tool for troubleshooting high jitter and variable latency on a wireless network is a spectrum analyzer, as it can identify sources of interference.
Step-by-step explanation:
To address the issue of high amounts of jitter and variable latency in a wireless network due to possible interference, the most appropriate tool for the technician to use is a spectrum analyzer. This device allows technicians to visualize wireless signals and the distribution of frequency bands in the environment. It can help identify and locate sources of interference, such as other networks or non-802.11 devices.
A spectrum analyzer displays the strength of the signals within different frequency bands, making it possible to detect overlapping channels, which could cause interference and result in jitter on the network.
To troubleshoot the issue of high jitter on the wireless network, the technician should use a Spectrum analyzer. A Spectrum analyzer is a tool used to analyze the frequency spectrum of signals and identify any interference or non-802.11 devices that may be causing the issue.
By using the Spectrum analyzer, the technician can determine if there are any other networks or devices operating on similar frequencies as the wireless network and take appropriate actions to mitigate the interference.
