Everything WiFi Flashcards
The behavior of radio waves when they are transmitted from one point to another; into parts of the atmosphere.
Radio Wave Propagation
The attenuation across distances
Free Space Path Loss
When signal hits a smooth object and bounces off the surface.
Reflection
When a signal passes through an object and the signal is redirected.
Refraction
When an object take in the signal and retains some or all of it.
Absorption
When an object takes in the signal and retains some or all of it; reflects the signal in many different directions.
Scattering
When another signal is on a signal is on a similar bandwidth to your WiFi network, overpowering or corrupting the Wifi Signal.
Frequency Interference
When overlying access points use the same channel or channels with overlapping frequencies causing connectivity issues for clients.
Co-Channel Interfernce
When construction materials and contents of a home are reasons that a WiFi signal will not travel as far as it is rated.
Physical Interference
Is when two channels’ strength is such that they interfere with one another.
Adjacent Channel Interference
These three gateways integrate voice, internet access, wireless router, and primary modem functionality.
XB3, XB6, XF3
The 2.4 GHz has how many channels?
14 channels
Of the 14 channels in the 2.4 GHz network how many are non-overlapping?
3 non-overlapping channel; 1, 6, 11
The 5.0 GHz has how many channels?
23 channels
These standards were originally developed for Wireless Local Area Networks.
