Possible Causes of Network Connection Issues in a Building Equipped with Light Sensors

A building is equipped with light sensors that turn off the fluorescent lights when natural light is above a certain brightness.

Users report experiencing network connection issues only during certain hours.

The west side of the building experiences connectivity issues in the morning hours and the east side near the end of the day.

At night the connectivity issues affect the entire building.

Which of the following could be the cause of the connectivity issues?

A.

Light sensors are interfering with the network

B.

EMI from the lights is interfering with the network cables

C.

Network wiring is run perpendicular to electrical conduit

D.

Temperature changes are causing attenuation in copper cabling.

C.

The given scenario suggests that the building is equipped with light sensors that turn off the fluorescent lights when the natural light is above a certain brightness. Users report experiencing network connectivity issues only during certain hours, with the west side of the building experiencing connectivity issues in the morning hours and the east side near the end of the day. At night, the connectivity issues affect the entire building.

Based on this information, the most likely cause of the connectivity issues is the network wiring running perpendicular to the electrical conduit (Option C). This is because electrical conduit and electrical wiring can cause electromagnetic interference (EMI) with network cables, leading to degraded network performance or connectivity issues. Running network wiring perpendicular to electrical conduit can increase the likelihood of EMI.

Option A, which suggests that light sensors are interfering with the network, is unlikely to be the cause of the connectivity issues. While it is possible for poorly designed light sensors to cause EMI, this is rare and not typically associated with the type of connectivity issues described in the scenario.

Option B, which suggests that EMI from the lights is interfering with the network cables, is also possible. However, the fact that the connectivity issues are time-dependent and affect different parts of the building at different times suggests that EMI from the lights is unlikely to be the sole cause of the issues.

Option D, which suggests that temperature changes are causing attenuation in copper cabling, is also possible. However, this is less likely than Option C, given the specific time-dependent and location-dependent nature of the connectivity issues.

In summary, based on the information provided, the most likely cause of the connectivity issues is the network wiring running perpendicular to the electrical conduit.
