Radio frequency interference (rfi) is simply either man-made or natural sources that interact with radio waves. A natural source - is the crackle you hear from your radio when there's a lightning storm between you and the transmitter. A man-made source - could be something like hearing a taxi-cab radio over a 'normal' radio program.

Which wireless standard is least prone to radio interference?
802.11a as it only operates on 5gz, a frequency that is generally unused by other devices.
Why does your radio whistle when you step on the gas...the whistle gets louder the more gas I give?
The alternator or coil needs suppressing. Electrical devices make radio frequency interference. Go to an I.C.E shop for best suppressor.
Interference between two radio signals to improve radio images?
Interferometry
Why is FM undesirable in the standard AM broadcast band?
The carrier frequency will cause interference with any AM station on or near that frequency.
Does XM radio have static interference?
XM radio does not have static interference. It's a digital signal, so you'll either get a crystal-clear sound or none at all.
What cable is NOT subject to electromagnetic interference or radio frequency interference?
Fiber-Optic
What are reasons for electrical interference on car radios?
Electrical interference in a car radio is the same as electrical interference on any radio. Radio interference is literally the sound of the air. When a radio signal is broadcast, the frequency that was previously only occupied by air is overpowered and drowned out, thus you hear the broadcast frequency clearly. When the broadcast frequency is weak (i.e. you are too far away or something is blocking the signal), the frequency cannot completely overpower the air and thus you hear some of both.
Is fiber optic immune to electromagnetic interference and radio frequency interference?
Yes. It is immune to EMF (electromagnetic interference) and does not create its own EMI. Also, it is immune to RFI, or radio frequency interference. This is because fiber optic carries signals as light waves instead of electrical impulses.
What is a RF Lead?
What is sometimes called a Radio Frequency lead is a shielded cable used beween pieces of equipement to reduce the effects of radio frequency interference.
What is a snap choke core?
It is a ferrite core over coax cable, AC or audio cord. It prevents electro-magnetic interference (EMI) and cuts down on radio-frequency interference (RFI).Prevents electric magnetic interference (EMI) and cut down on radio frequency interference (RFI)Simply snap it over any coax cable, AC or audio cordRoSH compliant
What can you do when everyday at lunchtime wireless users complain of lack of connectivity?
reduce the radio frequency interference around the WAP
What cable is not subject to EMI electromagnetic interference and RFI Radio frequency interference?
-- galvanized steel cable -- dyed silk cable -- fiber-optic cable
Which wireless standard is least prone to radio interference?
802.11a as it only operates on 5gz, a frequency that is generally unused by other devices.
Lowest frequency at which destructive interference is observed?
Constructive and destructive interference can occur at any frequency. Superposition of waves is not dependent on a specific frequency.
Define the frequency reuse?
Frequency reuse is the process of using the same radio frequencies on radio transmitter sites within a geographic area that are separated by sufficient distance to cause minimal interference with each other. Frequency reuse allows for a dramatic increase in the number of customers that can be served (capacity) within a geographic area on a limited amount of radio spectrum (limited number of radio channels).
How can you say interference in a sentence?
There was interference with the radio signal.
How does concrete interfere with wireless communication?
Concrete interferes with wireless communication by weakening the signal of the radio frequency. Concrete's ability to weaken or completely stop radio frequencies from travelling through it are what causes the interference.
