2. Signal-to-noise ratio - Wikipedia

   en.wikipedia.org/wiki/Signal-to-noise_ratio

   In the above formula, P is measured in units of power, such as watts (W) or milliwatts (mW), and the signal-to-noise ratio is a pure number. However, when the signal and noise are measured in volts (V) or amperes (A), which are measures of amplitude, [note 1] they must first be squared to obtain a quantity proportional to power, as shown below:

3. Wireless site survey - Wikipedia

   en.wikipedia.org/wiki/Wireless_site_survey

   There are three main types of wireless site surveys: passive, active, and predictive. [5] During a passive survey, a site survey application passively listens to WLAN traffic to detect active access points, measure signal strength and noise level. However, the wireless adapter being used for a survey is not associated to any WLANs.

4. NetSpot - Wikipedia

   en.wikipedia.org/wiki/NetSpot

   NetSpot provides all professional wireless site survey features for Wi-Fi and maps coverage of a living area, office space, buildings, etc. [3] It provides visual data to help analyze radio signal leaks, discover noise sources, map channel use, optimize access point locations. Also, the application can perform Wi-Fi network planning: the data ...

5. Eb/N0 - Wikipedia

   en.wikipedia.org/wiki/Eb/N0

   is the carrier-to-noise ratio or signal-to-noise ratio, B is the channel bandwidth in hertz, and f s {\displaystyle f_{s}} is the symbol rate in baud or symbols per second.

6. dBm - Wikipedia

   en.wikipedia.org/wiki/DBm

   Minimal received signal power of wireless network (802.11 variants) −111 dBm: 0.008 pW = 8 fW: Thermal noise floor for commercial GPS single-channel signal bandwidth (2 MHz) −127.5 dBm: 0.178 fW = 178 aW: Typical received signal power from a GPS satellite: −174 dBm: 0.004 aW = 4 zW: Thermal noise floor for 1 Hz bandwidth at room ...

7. Sensitivity (electronics) - Wikipedia

   en.wikipedia.org/wiki/Sensitivity_(electronics)

   This is an example of a case where sensivity is defined as the minimum input signal required to produce a specified output signal having a specified signal-to-noise ratio. [2] This definition has the advantage that the sensitivity is closely related to the detection limit of a sensor if the minimum detectable SNR o is specified ( SNR ).

8. Noise (electronics) - Wikipedia

   en.wikipedia.org/wiki/Noise_(electronics)

   The noise is a summation of unwanted or disturbing energy from natural and sometimes man-made sources. Noise is, however, typically distinguished from interference, [a] for example in the signal-to-noise ratio (SNR), signal-to-interference ratio (SIR) and signal-to-noise plus interference ratio (SNIR) measures.

9. Received signal strength indicator - Wikipedia

   en.wikipedia.org/wiki/Received_signal_strength...

   Cellular signal strength of -74dBm (or 66 asu) displayed on a smartphone.Also shown: signal bars of two cellular networks, and signal bars of a Wi-Fi network. In telecommunications, received signal strength indicator or received signal strength indication [1] (RSSI) is a measurement of the power present in a received radio signal.
