Question

How noise can affect wireless network and what is general approaches to resolve it?

Answer 1

A wireless Network / signal consists of the Main signal to be transmitted and the external disturbances that affect the quality of transmission of Signal is called Noise.

#Effect of Noise on Wireless Networks:

● Ambiguity in Message signal - the sender and the Recipient might not understand each other properly due to disturbing Noises.

● weakening of signal - signal might Damp out due to dominating Disturbances.

● Hinderance to Signal - the important Data signal may even get blocked due to Noise Domination leading to incomplete transmission of the signal.

# Basic Approach to Remove Noise Effect:

● Proximity - we should maintain a proper Distance between the network for higher efficiency.

● Interference - Different wireless Device work on same frequency band hence they create interference. Thus, such Devices must operate at different frequencies for proper working of the wireless network.

● Faraday Cage - It is an external Device which can be used to remove the external noise. Thus, proper transmission of signal is maintained by the device.
