A network administrator notices that some newly installed Ethernet cabling is carrying corrupt and distorted data signals. The new cabling was installed in the ceiling close to fluorescent lights and electrical equipment
Two factors may interfere with the copper cabling and result in signal distortion and data corruption are :
EMI
RFI
Explanation:
- EMI (electromagnetic interference) is the disruption of operation of an electronic device when it is in the vicinity of an electromagnetic field (EM field) in the radio frequency (RF) spectrum that is caused by another electronic device.
- During EMC testing, radiated emissions measurements are made using a spectrum analyzer and or an EMI receiver and a suitable measuring antenna.
- EMI (Electromagnetic Interference) is also called RFI (Radio Frequency Interference).
- Conducted RFI is unwanted high frequencies that ride on the AC wave form. Radiated RFI is emitted through the air. There are many pieces of equipment that can generate RFI, variable frequency drives included.
- The internal circuits of personal computers generate EM fields in the RF range.
Yes you must update or do something first but then you can
