Which measure can help control RFI effects on wireless networks?
- Ensure the humidity and temperature levels are set as low as possible.
- Ensure the number of wireless NICs exceeds the number of wireless phones.
- Ensure the wireless network is on a different frequency than the offending source.
- Ensure each wireless NIC is configured to operate at different frequencies from all other wireless NICs.
A wireless network (IEEE 802.11) can be affected by radio frequency interference because it shares the same radio frequency range with other devices, such as cordless phones.
